Audio: Testing audio formats part 2

  • Feb 4, 2013

    I have the standard sound system and I'm noticing a minor glitch playing WMA files at multiples of 12 seconds (like 48 or 72 seconds) where the song stops playing for 1/20th or 1/10th of a second, then just keeps going like nothing happened. Is no one else noticing that? I am happy to say that after a week with the car (which came with 4.2 firmware) that's literally the biggest issue I've run into.

    Are you using WMA lossless? Or lossy WMA? If so what bitrate? I only tested a single WMA lossy file. I didn't notice, but was too busy grinning like mad. I havn't noticed the few times I used WMA Lossless files in my car. I don't have a big memory stick, so I have been using MP3s.
  • Feb 4, 2013

    It's lossy, 128kbps. I may try converting to .mp3s and see what happens.

    I tried playing some flac files and multi-channel flac files when I did my test drive on a car running 4.0. The standard flac files played fine (sounded better with Dolby off) but the multi-channel ones did not. My Denon receiver also doesn't handle the multi-channel FLAC files.

    I am pretty sure my WMA file that I played was very high bitrate 256 or above. I also did it way back in October. I just use mp3 for lossy stuff, and WMA for my lossless. I'll rip some more WMA lossy stuff and see if I can replicate what you are hearing.

    Am I missing it, is there some way to shuffle songs within an artist or genre off of a USB drive?

    The short answer is no. The work-around is that you can mess with the names and other tags to get a varied, not random, order.

    USB External Hard Drive Works

    I'm on 4.2. I can use my Toshiba 300GB USB External Hard Drive to store FLAC music files (44.1 Hz Stereo) and they play fine through the car system. The file system is FAT - maybe that is the secret as I see other people have had problems with NTFS. All I need is a Shuffle feature and I am in car music heaven. I wonder why it sounds rather muddy if I turn Doby surround on. Sounds perfect with Dolby off.

    FWIW, I've been re-ripping my entire CD collection to FLAC. To my ear, there is a dramatic step-up in sound quality with the Sound Studio using FLAC rather than MP3 256kps. Ripping ~1,000 discs is time-consuming....

    Hi fellow Robert,

    I'm glad the S supports FLAC. Would you mind sharing what size your average 4min song becomes once ripped? I'm thinking of also using FLAC, but I only have a 64GB USB key so I'd like to get an idea of how many songs I'll be fitting on there.

    Thanks!

    I find a four minute track takes about 24 MB when compressed using FLAC encoding. USB hard drives are considerably cheaper than USB flash drives for the same amount of storage. 1TB drive costs about $70. But it is possible you may need to reformat with FAT for Model S to read them. I am continuing to experiment with different drives and file systems.
  • Feb 24, 2013

    There is a glitch (or extra quiet-time) forced between tracks. I assume this is not what you are seeing? The glitch between tracks is not noticeable on most material, but a few CDs run the music from one track to the next without a break. This works fine playing the physical CD, or a media player on the PC, and on smartphones, but the Tesla audio always sticks an extra 300ms (or so) blank between the tracks that shouldn't exist.

    Notice that USB hard drives are very likely good old mechanical drives. I can imagine they don't like the forces when you go all lead foot on the car :)

    Yeah I'd rather stick to a flash drive. Smaller and less susceptible to environmental issues.

    I've been using a Toshiba USB 300GB Hard Drive for 3 years in my last 2 cars and have never had a problem as long as the car system supports them. I am pleased to find the Model S works fine with mine. Specific models are designed to be rugged and portable and I have not found them to be affected by acceleration. You might want to watch temperature extremes, but they are rated for -40 to +65C (smaller range while being used). They are about 10% of the price of the equivalent flash drive. You can get about 40,000 FLAC tracks on a 1TB USB hard drive. Flash drives are fine for MP3, but if you are going to use FLAC the storage size is a big constraint. 1TB of flash storage is probably going to cost around $800 while you can get an equivalent mechanical drive for less than $80.

    Hi interleaf,

    Out of curiosity, where do you keep your external HDD in your Tesla? The USB ports are in a place where there's no storage, so I'm wondering what your solution was...
  • Feb 25, 2013
    interleaf2
    I keep it in the center storage well attached to one of the USB slots. The USB cable is about 10 inches long.
  • Feb 25, 2013
    clea
    I think the question was about, at least for me it was, are you worried about its visibility in the center storage area making it a target for thieves doing a smash and grab? Or do you move it somewhere hidden when you park in a public place?
  • Feb 25, 2013
    zax123
    Yeah pretty much... the CCI would be great for this kinda thing, but it's really too expensive in my opinion. :(
  • Feb 25, 2013
    interleaf2
    A used 300GB hard drive is worth about $25 max, so not much of a thief magnet. I'd be more worried about a flash drive of similar size which would be more like $400 in value and I would keep that in my pocket. All my music is stored on my home computer, so I can easily recreate the disk if necessary. I've never had any concerns about it in the last 3 years. If I were in a really dodgy part of town I suppose I might take the drive with me, but I probably would not park a Model S there in the first place. For me having a large tray on the floor is actually more useful than the CCI. I keep lots of different things there. Log book, small change, pens, phone charger, etc. It's a perfect place for the hard drive to sit. Before the Model S was delivered I planned to buy the CCI when available, but not now I have actually got the car. The standard set up works great for me except for the cup holders being set in an awkward spot.

    I have confirmed that several portable USB hard drives formatted with FAT32 will work fine with the Model S music system. However those formatted with NTFS will definitely NOT work and I suspect strongly that exFAT will also NOT work.

    I now am using a new 1TB Buffalo Ministation Stealth 2.0 USB drive in the car which cost me $70 from Amazon and I calculate that it will hold about 40,000 average 4 minute tracks stored in FLAC format. The Tesla allows me to access by Artist, Genre, Song, Album or Folder. It looks up the album artwork and genre as it creates its directory. Obviously if you have a huge collection it is going to take some time to retrieve all this from the internet, so it's probably best to leave the drive attached when not in use.

    Being lossless, I find that FLAC compression needs about 7 times as much disc space compared with typical good quality MP3 files or other lossy compression formats. The typical 128GB flash drive is also going to cost about $70 but will only hold about 5,000 FLAC tracks. Above 128GB flash drives start to get very pricey (although this will no doubt change quickly as time progresses).

    So I reckon if I want to have 40,000 tracks at my disposal while driving I can either use MP3 format with a USB flash drive or FLAC with a USB hard drive. In both cases the storage medium is going to cost about $70. Of course if you use MP3 and a USB hard drive you could get about 280,000 tracks on a single 1TB disk drive. Since I paid extra to have the upgraded sound system in the car I thought I ought to avoid quality degradation due to lossy sampling and compression. Plus I don't have 280,000 songs.

    You could get a 2 TB hard drive but the cost would treble for double the capacity, so it seems like 1TB is the sweet spot. It seems like 64GB is the current sweet spot for flash drives.

    In a couple of years it should be possible to get 1TB flash drive for a reasonable price.

    Using FLAC, one CD requires anywhere from 150 MB to 440 MB. A "typical" CD seems to be about 250 MB. Led Zeppelin's Mothership disc 1 seems to be an extreme outlier at 440; other "big" discs are more in the mid 300's.

    I wonder if ext2, ext3, ext4 or other common Linux disk formats would work. It seems like they should since the consoles underlying OS is Linux, though I don't think you'd get much benefit from it (unless 2TB is not enough space for you)
  • Feb 26, 2013
    zax123
    So on my 64gig USB key we're talking about 250 albums. For now, that's plenty. :)

    Besides actually BUYING the physical media, is there someone online you can purchase lossless audio files? Does anyone know?
  • Feb 26, 2013
    ElSupreme
    I don't know of one. Amazon was advertising that they would offer that in the past. But like Robert.Boston I like the physical disc as an archival piece also.

    Back when I was actually using CDs in the car, I would actually dupe my real CD and use the burned one in the car. That way if I ever removed a disc I could ?(not that I always did) just throw in on the floor and not really worry about it.

    Last time I researched this we had almost no support for good quality legal downloads (i.e. not mp3) with a decent selection in Canada. However I found a site that lists a bunch of sites supporting cd quality flac here Music Download Sites (16/44 a list) | AudioStream and some of them are supported in canada (one is 7digital but not a great selection yet) but they also give a list of better quality here HD Music Download Sites (a list) | AudioStream. Remember though that you need to test whether it will allow you to purchase and download once you state that you are Canadian. For example, hdtracks still only supports downloads to US residents.
  • Feb 26, 2013

    Thanks for the info Clea. :)

    I hate to say the obvious here and maybe it's a forum no-no, but what's stopping us from using a proxy to download them? We're still paying our dues to the artist/label... That kinda thing is gray to me...

    I checked out the sites... definitely not as simple as iTunes or Amazon Music Store... yikes.
  • Feb 26, 2013
    clea
    I believe that they are obliged to check and if you use a proxy you will also have to use a payment method that comes from the same source (i.e. use a US credit card). Often it seems it is the labels themselves that have the region based restrictions on its downloads and this is especially true of the higher quality tracks but i am ignorant as to what is behind the logic of a label making hd audio available in one region and not the other.

    Ok gang - since you all know what you are all taking about - give me the "Readers Digest" version of how to do all this. Being quite a novice at this sort of thing, how about a step by step guide for a lay person like me to put music on say a 32 or 64 GB USB stick. I would really appreciate it. My experience level is putting stuff on I-tunes, then loading them onto the player to listen to.

    Thanks!

    Get a computer, preferably a desktop with at least 2 CD drives. But any computer with a CD drive will work.

    Install a music program (you already mentioned it so), say iTunes.

    Go into ripping settings and pick MP3 and pick a bitrate of 256. Higher numbers will get you better quality, but you will fit less of them onto your USB stick. (Save your settings)

    Also in your ripping settings you should have a default folder where your files end up, remember this folder. (Save your settings)

    Put a CD into the drive, it should ask you if you want to rip it, say yes. When done repeat. (Some software will let you do this with multiple CD drives at once).

    Once you have your music ripped go to the folder you were supposed to remember with a file browser (explorer, Win; or finder, Mac). Plug in your USB stick. [THIS WILL REMOVE ALL INFORMATION FROM YOUR USB FLASH DRIVE start]Format it as FAT32 (it probably is default to this). Typically you just right click on the USB icon in your file browser and 'format' is an option.[ end THIS WILL REMOVE ALL INFORMATION FROM YOUR USB FLASH DRIVE] When this is done open your USB stick in a file browser window. Then drag your music folders (normally defaulted to artist) to your USB stick. You only need to format your USB drive once.

    Properly remove your USB stick and insert into Model S USB port. Everything should work.

    What sort of music file, directory and name structure do you guys recommend for the s?

    I currently have all my mp3's stored in one directory. Files are artist-song.mp3, with embedded album art. Usually I just shuffle it and it works fine. But I would like to know if I should modify this setup over the next 2 weeks before my s arrives.

    On average, I find that FLAC (or Apple Lossless) takes up about 1/2 the space of the WAV file and 2x the space of 320kbps AAC. Which is probably close to 256kpbs mp3.

    So a reasonable rule of thumb is that FLAC or Apple Lossless will get you:

    - twice the # of songs on the same drive as the uncompressed CD versions
    - 1/2 the # of songs on the same drive compared to storing the songs in high quality mp3/AAC.

    Not sure about 128kbps mp3/AAC though as I don't typically use those.

    Years ago, when I started ripping my CD's, I wanted to be able to know everything about the file from just looking at its filename. At the suggestion of a friend, David Steele, I settled on a " ~ " separator (space tilde space) that wouldn't cause any problems in any reasonable filesystem, and I name files like this:

    <Artist> ~ <Album> ~ <Track# in 2 digits> ~ <Track Title>.wav

    Obviously I also tag the files when converting to other formats, but it's great that I can always tell anything I need from the filename, and also that programs like MediaMonkey can get the tags from the filename automatically... lots of time saved that way.

    If you want to buy high-def soundtracks, HDtracks high resolution audiophile music downloads has a very good collection of music that can be downloaded in lossless or other hi-def formats. As for organization, I create a folder for each album, which makes it simpler to move albums on/off a flash-drive for the car.
  • Feb 27, 2013

    If you're into electro, beatport has the option to sell tracks as either AIFF or WAV. I have read the entire thread to see what's supported but those would be lossless and purchase'able'
  • Feb 27, 2013
    dadaleus
    Nice guide by Elsupreme. Personally, I'd argue for Lossless or 320k. Media is cheap and its possible to down convert. But you don't want to have to rip your disks again.
  • Feb 28, 2013
    ElSupreme
    Yeah I just really simplified things, for people that just want their music in their car. 256bps mp3 is 'good enough' but not great. If you want to keep a library of all your music rip to FLAC or WMA/AAC lossless. Then down convert if you don't need the quality (read 'using earbuds'), or need more songs and don't have the space.


    I normally put 192bps on stuff I use earbuds with. 320bps on things I use my (fairly crappy) headphones with. Things that have more than 100GB get full Lossless files regardless of what is being played. In my previous car I would use 320bps, because it was loud, and the Stereo was just OK. With the S I am thinking I need to pony up for a 128GB USB stick, so I can get a good portion of my music on there at once. I might buy a bunch of those super low profile 32GB ones and just swap out as needed.
  • Mar 27, 2013

    I've always encoded at 256bps mp3 and then 256 AAC with iTunes. Am thinking about encoding in ALAC since I have almost all Apple products. Does the Model S still not support ALAC or is FLAC the better way to go (as a general rule for future backup). I don't see Apple going anywhere anytime soon but if Tesla won't support it then maybe FLAC is better. Thanks.

    The cover art only comes via the 3G connection. There is no way to override it and it ignores any art on your USB device.

    Cover art can be imbedded in your audio file (some formats) and/or provided as a jpg in the same directory as the album.

    I believe they are using CDDB, which is very comprehensive, but has errors, especially on collections. Also keep in mind many albums have been released with different cover art for the same album, so the one served by CDDB may be correct, but just not the same as your personal album.

    Hopefully Tesla will have an update that allows us to select to prioritize where to get the cover art - local or via 3G CDDB.

    Very strangely, I have one album that displays a photo of two people in portrait mode! They are not the artists and it is clearly not a CD cover. For me, I estimate about 5-10% of the covers are wrong.

    For my initial USB stick load for the S, I did FLAC files ripped direct from actual CDs @ 44.1Khz / 24 bit. The files sound great (essentially exactly like a CD would with no compression artifacts). The compression is only about 2 or 3 to 1, but the improvement in quality over lossy compression is worth the extra storage space requirements.
  • Mar 27, 2013
    rcc
    Can you hear a difference between 44.1 / 16-bit and 44.1 / 24-bit given that the source is 44.1 / 16-bit?

    As for ALAC vs. FLAC, I rip to ALAC using iTunes because I play that on the ipod. Then (on Windows), I copy files en masse and use MediaMonkey to convert to FLAC with a song, artist, album type title to make sure I don't get collisions.

    This because the Model S doesn't support ALAC for some reason whereas it supports FLAC just fine.
  • Mar 28, 2013
    ClearwaterBchSteve
    I have not done any extenisve comparisons between 16 and 24 bit FLACs created from CDs. However, even though the source material is only 16 bit, using 24 bit in the conversion should theoretically provide a bit more headroom during the compression process - it's worth a good listen because if there truely is no perceptable difference, the 16 bit destination files would use less space.

    A quick file-size update for everyone...

    Just got my 128GB USB stick for the Model S, and ripped 3471 songs to FLAC. My starting point was 16-bit/44.1-kHz WAV files ripped directly from the original CD's. The total file size for WAV files was 140GB (40MB/song) and the total file size for FLAC was 80GB (23MB/song). The resulting lossless compressed files are (as a group) 43% smaller than the originals.

    On the way to Tesla service center to trade in my Roadster, another car sideswiped me and scratched up the Roadster. So the repair process is holding up the trade-in and delivery process.

    Sometimes. About half my music just shows ? instead of a picture and XXXX XXXX instead of text. On the remaining half, most of the album covers are tiny (unseeable) with a large border. It's happier when the Nav system is doing guidance and nothing related to music is displayed on the instrument cluster. However, the music sounds great (at least the ones that are lossless).

    IS ALAC the same as Apple Lossless? What's the difference between FLAC and Apple Lossless?

    I'm loving the sound package in the S but keep hearing about how great it is with lossless. I'd like to experience this. So I'm thinking of using MusicShifterCD Ripping Service, CD Conversion Service
    to rip all of our CD's. Yes, I'm lazy.:smile:

    Seems as though everyone likes FLAC on the MS. I'm a MAC guy. IS one or the other easier to work with as far as down converting them back to MP3 for IPods and iPhones etc...?
  • Mar 29, 2013
    dsm363
    ALAC is Apple Lossless Audio Codec. FLAC and ALAC are both lossless formats but not sure there is much difference between the two other than ALAC is backed by Apple and FLAC has been around longer and is more of an open source format I believe. I have all Apple products as well so would prefer doing ALAC since I'd be ripping the CDs myself in iTunes but since the Model S doesn't support ALAC (yet), maybe going with FLAC is the way to go for the Model S at least.
    Listen to FLAC audio files on iOS devices | Macworld

    In terms of all your Apple products, ALAC would be simpler. Maybe that company can convert them to both formats for you? You could put the FLAC files on a 128GB USB thumb drive and then all the ALAC files go on your Mac with the hopes Tesla supports ALAC in the future.

    Jerry to the rescue!:

    I'd probably have them do all ALAC if you had to pick one then selecting the songs you want and convert them yourself to FLAC.

    Mine says 0.9.1. That's the stable version (says Latest on the site). Note that you need to use Rosetta for this--or at least I did because the "Formats" section in the Preferences didn't work correctly without it in Snow Leopard. Perhaps this is fixed in the unstable version.

    You got ext4 working? When I plugged in a pen drive with ext4, it hung the main screen repeatedly. It seemed like they forgot to handle a return code from the mount system call, resulting in the UI never getting whatever message it was expecting. I'll try this again tomorrow. What firmware version are you on? My car came with 4.2 and I haven't been offered the upgrade to 4.3 yet.

    I'm about to try NTFS today, since I have the complete works of Gustav Mahler ripped from CDs, and it turns out Austrian-oriented song names contain multibyte unicode characters which FAT32 doesn't support.

    In other news, the central computer only seems to understand MBR-style partition tables. It completely ignores a pen drive containing GPT, which many modern Linux distros use as a replacement for the archaic other thing from the 80's. When I format my pen drive in Fedora, I have to be sure to tell it to do an MBR partition scheme.

    Thanks Jerry. That's the version I downloaded. I'm running Lion and the prefs worked without any help. Still not sure how the album art works. Does the 3G in the car just grab it, or do I have to have the tiff (album cover) in the folder on the usb?

    I loaded a 4GB stick with about 60 FLACs just to see if I could tell the difference. I'm no audiophile in the least. I already think the upgraded sound is great. I thought it was even better with the FLAC stick.
  • Mar 31, 2013
    jerry33
    The art comes over 3G. In my case that's almost no art and what's there either doesn't match the album or is tiny with a very large border (about 5% displays correctly). Most of my songs have no text either, just XXX where the characters should be.[/QUOTE]

    ALAC is the Apple Lossless Audio Codec. Flac (Free Lossless Audio Codec) is probably a bit better supported since it is an open standard. Android supports it as standard and it is typically well supported by open source software. Encoding flac is a lot faster than ALAC.

    Would it be possible for someone who is driving a MS and using a flash drive and has a Mac for music to take a screen shot of what the format looks like when you download your music from the flash drive to the touch screen. Maybe someone can help me with getting my music into the MS. Do not have the car yet but trying to have some music ready when I do get it. I took some of my CD's and ripped them into iTunes. When I plug in my flash drive it comes up on my desktop, I tried to export my library to the flash drive but when I access the music it comes up in a spreadsheet and there is nothing you can do with it. Then I tried to drag the albums to the flash drive and that seem to work. But obviously cannot see the format that would show up in the MS. I know there are many of you out there that are very IT savvy, so if anyone could help it would be appreciated.

    Sounds as though you got it. I'm not sure it matters how you put the albums on the flash drive. ON the MS audio screen you will choose "my devices"and then "usb drive." Then you can get a list by album, song, or artist but only in alphabetical order by what is on the usb. No shuffle, or playlist. Hopefully this is coming.

    has anyone tried an ssd drive, say 256GB, in a usb enclosure? is there a possibility this will work, or is there a linux/tm file system limitation happening here? i tried a western digital passport drive (platter), won't work. i'd like to get more music than the thumb drives will hold in the s. so, ssd, anyone? i have a few lying around and thought i could just throw one in an enclosure and try that.

    also, my library is apple lossless. has been for years. ain't gonna change now. i can't see why tm won't support alac, unless apple charges a ton for licensing which would be stupid on their part, but i don't know.. i do know my transporter/slim devices server (now logitech) serves up alac just fine. i did try mass converting a chunk of my lib to flac to test but haven't found a combo that works yet. loathe to buy a big thumb drive when i have so many ssd's here already. my library is probably 300GBs, would be great to have it all....

    thanks for thoughts.

    Thanks Al, I guess I will have to get the car to see if it works.

    Turns out my 128GB flash drive was formatted with exFAT, which the Model S can't read. The Model S can read FAT32, which is capable of volumes up to 2TB... but Windows is deliberately crippled and won't format a drive in FAT32 if it's > 32GB. Found a third-party format tool, reformatted my 128GB flash drive with FAT32, put all my music back on it, and Bob's your uncle.

    My thanks to someone on another thread who explained the solution to me.

    Sandisk worked intermittently for me. I think the problem was its length meant that it would jostle in the plug.

    My pleasure. It should work. If it doesn't, check back here and these smart people will get it up and running. Lots of really smart computer folks on this forum.

    Incidentally, you know you can play the same format from your iPhone over bluetooth in the car at the same relative quality? If you're just copying MP3's from iTunes you might as well play them from the phone. This will also allow true random shuffling, playlist playback. Unfortunately (for now at least) controlled from the phone with the exception of Pause, Play and Forward or Reverse.

    I think the reason people are using flash drives is to get the better (Lossless) formats. Everyone seems to agree that FLAC works on the MS. I've been playing with it and at first I didn't really think I heard a difference.Many friends who have listened to the exact track over the phone and then from the usb in FLAC format think the difference is very obvious. A lot of the audiophiles on here say that the upgraded sound is designed for these Lossless formats.

    Jerry33 turned me on to a program called MAX earlier in this thread that will rip your actual CD's into the FLAC format and then you can just drop the created folders on the usb stick. It worked well for me (OS10.7.5) and is very easy to use. You DO need the actual CD's as I'm pretty sure it can't "upgrade" a format from iTunes.

    I've been ripping everything in ALAC now. Can MAX convert ALAC on my Mac to FLAC straight on the USB thumb drive? Doesn't look like the stable build has been updated since 2009.

    While it can't upgrade the format, if you have been importing CDs into iTunes using Apple Lossless, you can convert to FLAC with no loss of quality (and it's easier that sticking in a bunch of CDs).

    - - - Updated - - -

    Sure can. That's how I did it. It will even delete the mp3a for you on the thumb drive.

    Ok, you guys have lost me. I hate to seems so clueless, but please explain the Max conversion from ALAC to FLAC. In my previous thread I mentioned ripping my CD's into iTunes then dragging them to the flash drive. I have lossless set up. (Al, I cannot seem to do this even right side up).

    1. Put the thumb drive in the USB port on your Mac.

    2. Open Finder.

    2a. Navigate to Users->Merrill->Music->iTunes->iTunes Music. Here you will see a number of directories such as Books, Movies, Podcasts (which you don't want) and Compilations, Unknown Artist, and directories named after the artist or band which you do want.

    2b. Copy the directories you want to the thumb drive. (Note be sure to copy, not move. A copy will show a green plus sign).

    3. Open MAX

    3a. In Max->Preferences select Format and choose FLAC.

    3b. In Max->Preferences select Output and select the thumb drive. Check the Delete source files after encoding.

    3c. Close the Preferences and select File->Convert files

    3d. Use the + and select the directories on the thumb drive that you copied in step 2.

    3e. Click the Convert icon in the file conversion screen.

    I haven't tried an SSD, but I am happily using a 1TB portable USB hard drive (platter) containing FLAC files. As long as you format the drive using FAT32 it should work. Most platters come with NTFS so you need to reformat them before using in the Model S. I have found no issues with car motion disturbing the disk drive and this option gives you a lot of space for relatively little cost ($70). The Model S can catalog the drive quickly and allows you to search a huge collection very easily. Just a shame it doesn't support the shuffle function.

    huh. i tried this with a passport drive, 1TB, and it didn't mount. what brand are you using if i might ask?

    I am currently using a Buffalo MiniStation Stealth 1TB USB 2.0 Portable Hard Drive - HD-PCT1U2/BK. It was not recognized with the NTFS format but after I reformatted to FAT32 everything worked without a problem.

    That's good to know.

    Is "Apple Mpeg-4 audio" the same as ALAC? I'm guessing no. In which case I'll be inserting a lot of CD's.

    I think it can be both ALAC and AAC.
    Apple Lossless

    you can do 'get info' and summary in iTunes and it tells you there. Also, look at file size. ~5-10MB for a normal length AAC song and probably 20MB+ for a ALAC song.
  • Apr 8, 2013
    Al Sherman
    K thanks. Mine are AAC (3-6MB) so I guess I WILL be inserting a lot of CD's!:smile:

    fwiw, i've got a 256GB SSD playing great in the tesla. used an ocz vertex 4 in a 2.5" usb drive caddy, very fast, but requires two usb connections for enough power.. not a big deal as i don't really charge my phone in the car much anyway.

    the ssd is actually 512GB but when i formatted in fat32 that's all it gave me. i thought the volume size limit was much higher, but maybe not.. my plan now is to copy off and repartition the ssd into two of 250 each and recopy back, that way i can get the rest of the library on there, about 300GBs in apple lossless (converted to flac in xld, took about 20 hours. no kidding.)

    but sounds great. much better than ota radio or internet radio.

    EDIT: i take it back, operator error, i thought i put the 512 in the caddy, but i actually did put the 256 in there. so.. no mystery why it's only 256 gigs. d'oh.

    Tried lossless AAC today - car does NOT play them. It sees files, reads data and album art, but then says "Cannot play this song". Will try MP3s later. Also, car does not recognize 64GB stick formatted as exFAT. Only regular FAT works. Interestingly enough Mac can format stick as MS-DOS FAT, but Windows 8 only offered exFAT and NTFS formats...

    Was there ever a resolution on this issue? I also notice that my WMAs have hitches, pops, and cracks on playback (at several different bitrates). No problems with FLACs, or MP3s.

    Ah damn... I have been sitting all night (on my old T61 with sloooooow USB ports) copying 28GB og FLAC to my Cruzer fit thumbdrive to prepare for my mid-september delivery..

    I formatted it and thought to myself; lets do NTFS! I'm not a big fan of the FAT systems - and I've got all the NTFS permissions management stuff behind my ear every time I set up a partition.
    Just NOW I read the car doesnt support NTFS. Bummer.

    Well, time to set aside some extra disc space for my newly organized USB content...

    Keep in mind, the car needs to index all the files on the drive before you will be able to use it, according to my service center rep. I have around 7k mp3s on a 64GB flash drive formatted as FAT32, and I still have not been able to use the drive after over a week. According to the SC person, the car restarts the indexing process every time the drive is removed and/or the car is turned off. I don't have a very long commute, so the car has never been able to complete indexing before I reach my destination.

    i m playing the FLAC by using my USB 128gb. When i choose the song by folder no album pics were shown. The pics only shown up when i look up from album but i dont understand why the songs in same album were not at one album instead it separated one by one.

    please help!

    i am using mac and i tried metadata to tag all infos and album pics too.

    thank you

    I'm not sure I follow you entirely.
    When I tested FLAC (tried both 24bit 196kHz from an SACD rip I did and normal 16bit 44kHz from a normal CD), it ignored any covers or photos. It obtains the covers of the album via the on board Internet, as long as you have the artist / album / track name metadata in the actual files.
    However, from memory, it does not give you thumbnails when looking at the album list, only once you started playing a track.
