Core Audio Format -- Is anybody using it?

CAF files are a new(ish) Audio File Format/Wrapper type. Apple made it.
Qs
Is anybody using it with Logic? -- They do import
How? Why? -- They have several advantages but are relatively new, and it is not acknowlodged in Logic's documentation AFAIK.
Soooo...... There are other apps that support this Format, many including Logic will just plop them in as AIFF, for example. The format actually supports many audio file formats.
So within a CAF there can be audio of several types, sample rates, resolutions... They even support multichannel, markers, regions, music chunks.
In practice this could be a very useful format. Logic doesn't support all of it's features/formats but could be extended through QT or could hold limitations, probably why it is not listed as a supported format.
So is anybody taking advantage of this stuff, or hitting walls, having problems using these with Logic Pro?
Just Curious.

I have. I mentioned it imports -- prolly just certain cases where the underlying format is Logic approved. Haven't really worked with it much yet though with Logic as it was never cited that it was supported AFAIR. So I am guessing that it's underlying format needs to be a Logic approved one, but it imports 16, 24 and rejects 8 and 32. It also creates independent waveform overview files. I compared a 16 CAF to 16 AIFF, there were 3-6 lines which are different. Of course the header was in that list every time.
I was asking if there was anybody else using it so.... shrugs. It imports but I don't know of any advantage to use it, at the moment.
Maybe this will be the de facto 32/64 mixed file format when we get a new arrange window with sample resolution : ^)
Cheers, J
Gr8-1. ja, right -- is that a fat joke?

  • Which audio format should I use on my memory stick?

    Hi. My car has a Clarion HDD Navigation System MAX575 which is compatible with audio CDs and has a memory stick slot. I can't play MP3 CDs. Which file format should i use if I want to load music onto the HDD using a memory stick? I don't want to remove the unit.

    Windows on Intel Macs
    There are presently several alternatives for running Windows on Intel Macs.
    1. Install the Apple Boot Camp software. Purchase Windows XP w/Service Pak 2 or Vista. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.
    2. Parallels Desktop for Mac and Windows XP, Vista Business, or Vista Ultimate. Parallels is software virtualization that enables running Windows concurrently with OS X.
    3. VM Fusionand Windows XP, Vista Business, or Vista Ultimate. VM Fusion is software virtualization that enables running Windows concurrently with OS X.
    4. CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.
    5. VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not yet fully developed for the Mac - some features are not yet implemented - but it does work otherwise.
    6. Last is Q. Q is a freeware emulator that is compatible with Intel Macs. It is much slower than the virtualization software, Parallels and VM Fusion.
    Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system.
    See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion.
    Boot Camp is only available with Leopard. The Boot Camp Beta that was used with Tiger has expired and is no longer available for use. So contrary to the other poster's comment, Boot Camp isn't truly "free." You must purchase Leopard to get it.

  • Logic 8 crashing when Initializing Core Audio

    Does anybody have an answer for this? I am trying to launch Logic 8 on my G5 and every time it gets to initializing Core Audio it crashes unexpectedly. I tried launching it by disabling the core audio driver as the Apple site suggest and it works fine. But Apple doesn't say what to do then after that. I tried trashing the preferences (both from Logic 8 and the preferences from Logic 7 which were in the Logic folder in the Preferences folder). When I tried restarting after that it just froze when it came to initializing Core Audio. I couldn't even force quit it. It wouldn't let me. I had to manually shut down the computer by holding the power button.
    Pleeease help me. I'm fairly positive I have the most updated Core Audio driver (if anybody knows what it should be when running OS X.5.4 just so I can check that would be great). Thank you in advance.

    I tried all everything that you guys have recommended. I re-installed the audio driver just in case. I trashed all of the preferences, restarted a whole bunch of times and still it just keeps crashing when it gets to the Initializing Core Audio Driver stage. Should I try re-installing Logic Pro from the installer disc and then re-install all of the updates that have been released since?
    This is so frustrating. I'm not sure where the "crashed thread" is in the report but would that help if anybody saw that? I'm not exactly sure what part of the report to cop. The whole thing is way too long to copy and paste in one of these posts.
    Also, just to note, Mainstage opens up perfectly fine and I have no problems using it at all.
    Thanks.

  • The record has stopped because the audio format has changed

    I am using a JVC 9500E onto an XP pro machine with CS3 nothing else large empty hard drive. Firewire.
    Bringing a recording which was taken in one go with no changes - at 48Khz. PAL nothing odd - just continually opauses every 5-360 seconds with the error
    The record has stopped because the audio format has changed.
    using TAPe and Scene detect.
    anyone got any ideas?

    I know this is way too late and not really an answer, but I've had the same kinds of problems with PP2's capture function on 3 different decks on 2 different motherboards and 4 different OSes.
    My work involves capturing and repairing problematic and old or damaged tapes of all kinds. I understand that there will be some errors (tape stretch, breakage, etc) that can't be handled by the deck/camera hardware directly, and I have no problems with having to manually cue past such issues.
    But for otherwise fine and undamaged tapes, for PP2 to suddenly cease capturing, prompting to save less than 2 seconds' worth of video when all that happened was some minor tape noise or an audio frame missing is unhelpful at best and crippling otherwise. It's got to the point that PP2 is completely useless to me, when only the most pristine tapes with the most minimal of problems can be reliably captured.
    Since I've used the same hardware (cables, decks) to capture 1200+ hours of "through" footage (i.e. not MiniDV tape playback) without major problems, on the current system alone, that would seem to indicate that the system/cable/deck hardware is fine, it's the problem frame handling that's broken. When 3 different deck/camera manufacturers all react to the same tape problems in the exact same way (at least, for the few common tapes that I've had the ability to test on all 3 decks, all else being equal), that doesn't seem to me to indicate a manufacturer or model problem at all.
    However, Adobe's support response in each case (audio drops or minor tape dropouts) is "get the camera repaired by an authorised repairer". (It would seem that I'm an example of a particularly unlucky customer, buying 3 brand-new top-of-the-line 'duds' from 3 different manufacturers in as many years! What are the odds? I should buy a Lotto ticket...) That kind of support response is a real pity, since using the basic transport functionality outside PP2 seems to work perfectly for all but the most severe tape problems, but only using anything except PP2.
    To try to tell me that this is a deck hardware failure each time I've raised the same type of problem is disingenuous at best. But that's another story.
    The workaround (and yes, there is one!) is to use anything else except Premiere Pro 2.0 for any MiniDV capture operation. It's much easier to use VLC or Nero to perform flawed tape capture, and then use the otherwise sensational editing prowess of PP2 to fix the problems later.
    Pity.

  • Digi Core Audio 7. Anyone is using it without problems?

    I took ProTools 7.0 but I'm hesitant on installing it, particularly for DigiCoreAudio 7, because I'm using 6.9.2 which works fine with my Logic, and I wouldn't find bad surprises. Anyone is using it with Logic 7.2.2?
    Thanks

    Anybody knows the problem, and a solution?
    Matias.
    I think you need to ensure the Digi002 is connected properly. IE make sure the cables are connected all the way in, and that there is no other cables resting on top of them.
    Also, if you have many FireWire things hooked up to the same computer... get rid of a few of them. This helps the FireWire bandwidth.

  • How do I use 2 Core Audio devices at the same time in Logic w/out switching

    Hello, I use the Aardvark Direct Mix usb3 as my audio interface for mic and guitar. I just upgraded to Logic Pro 7 today and was hoping someone could tell me how I could use the Built-in Audio Core Audio driver along with the Direct Mix USB Core Audio Driver at the same time without having to switch Core Audio Driver's and than rebooting Logic. It is very frustrating doing that as well as not being able to hear my Logic audio during playback/record mode when I am trying to record via the USB3. WHat can I do? Thanks! If ther are both core audio, why can I not just use both of them at the same time? Why must a switch back and forth? Thanks!
    [email protected]

    THanks everyone! awsome article! Thanks for posting it, nh!
    The weird thing is, once I go up to the Menu and select Open Aggregate Device Editor in the AUDIO/MIDI setup utility and try to add a new Aggregate Device setup (step # 6 from the link), the only audio device available is the "Built-in Audio". What's weird is when I have the main Audio MIDI Setup utility open, every single drop-down menu/tab has the "Direct Mix USB 3 1.0.9.1" device right beneath the "Built-in Audio" option. To me that says that the core audio device is indeed recognized by my computer (obviously since I can record with it using Logic). Can anyone help me with this one? Any suggestions?
    Not that it should matter but, the hardware audio interface that I am using is made by the no-longer-existant company once known as Aardvark. I actually had to purchase a third party Core Audio driver just to have it recognized by OS X.
    This is the website where I purchased my audio driver :
    http://www.usb-audio.com/
    A little more on how this device and it's core audio driver function within Logic . . . (Hopefully this might clarify something I may be screwing up) . . .
    I launch Logic with its default Built-in Audio which allows playback of audio from the app. I than go up to Audio Hardware and Drivers and than drop the flip down Driver menu down to the second option, "Direct Mix USB 3 1.0.9.1." Logic than prompts me that I should try to (re)launch Logic Pro to load the appropriate CoreAudio.. I do that. Now I am ready to record guitar through the Direct Mix USB3, I just can't hear anything (unless I use head phones as an output from the Direct Mix).
    Anyway, you all probably already knew what I meant so explaining that was pointless. But my question is, if the Driver is obviously recognized by my comp in both the Audio MIDI Setup and in Logic, than why won't the Direct Mix device show up as a possibility for setting up an aggregate device? Any suggestions? Thanks!

  • What audio format does iTunes convert to and use?

    I got an ipod touch 4 a few months back, and it had to convert many of my songs to a different format. I need to put some songs on a rewritable cd/dvd to work in a cd player. I think it is an MP4 format. We tried it on a rewritable DVD-RW and a CD-R. Neither work. We tried on two different cd players. They act as if nothing was there. I need to know if Mp4 format is the problem and if iTunes can convert it to the right format. I can't find what format it converted my other songs to. Thanks for suggestions!

    iTunes does not convert the audio format unless you ask it to, either by ripping from an audio CD or using the conversion process.  (In iTunes for Windows it also does a conversion when a WMA file is added.) Other than that, it leaves files in the audio format they are in.
    When it does convert, it uses the format that you have selected in the "Import Preferences."  That value defaults to AAC, but also allows selection of MP3,  Apple Lossless, WAV, or AIFF.

  • Can I use a Protools HD interface as core audio for Logic 9?

    I am moving to a studio that already has Protools HD running on Mountain Lion.
    I don't especially like PT, so my question is... can I just use the PT HD hardware already there and run Logic and my AU plugs without using TDM?
    And if I do, how would it compare to the RME Fireface 800 I am currently using?
    Or would I be better off taking the RME and switching between the units depending on who was driving in the studio?
    Thanks in anticipation

    Yes, higher latency...
    Avid/Digidesign never put a lot of effort into their core audio drivers because they would rather have you purchase their hardware which uses proprietary drivers.
    There is an I/O limit but from the looks of it you won't be coming close.
    Offhand I'd say you will be missing the RME hardware but it may work for you.
    Keep us posted as to how it's going.

  • What format is the best audio format to use in iPod touch?

    I want to know the difference between MP3, AAC and Apple Loose-less audio formats and I want to know as soon as possible. I knew that AAC and Apple Loose-less formats use more size than MP3. That's fine with me. I just want to listen my songs with the best possible quality. What is the best audio format?

    Apple Lossless would give you quality identical to that of the original CD, but the files will be very large. A 3-minute song in Apple Lossless will be around 18 megabytes, versus about 6 megabytes for the same song compressed with AAC at 256 kbps. For an iPod, Apple Lossless is probably not an optimal format, since unless you have very high quality earphones or connect your iPod to a good stereo playback system, you won't really take advantage of the quality of Apple Lossless.
    For most people, the optimal tradeoff of quality versus file size is AAC at 256kbps. But as Niel suggestion, import a couple of CDs using different codecs and bit rates and decide for yourself. Quality depends on your playback system and what your ears can hear, so only you can decide what will be optimal for your situation.

  • How do you get core audio to work with maverick. I'm using logic pro X

    i'm having problem with core audio and maverick

    It sounds as if you have altered the Tempo after recording the Audio ( but before selecting +Follow Tempo+ ).
    This would make your Regions adapt from the old tempo to the new one, therefore changing their timing.
    Here's a bit more info:
    Audio files recorded in Logic Pro can follow the project tempo—inclusive of tempo changes—set in the global tracks.
    +Note: These audio files can also follow the first key signature set in the global tracks.+
    As an example: If you record a bass solo at 100 bpm, you can change the project tempo to 120 bpm and the bass solo will automatically be played back at the new tempo.
    The function works with all audio files that were recorded in, or bounced/exported from, Logic Pro.
    The function only works in the parent project (the project the audio files were created in). If you drag a file recorded in a given project to another project with the Finder, the file can not follow the project tempo.
    Bounced or exported files can only follow the project tempo if the “Add resulting files to Audio Bin” option was enabled in the Export or Bounce window—prior to the bounce or export.
    Files copied between two projects retain the ability to follow the project tempo.
    The project’s tempo information is used to tag the beats in the recording. The function works best if your audio files match the project tempo as precisely as possible. The longer your audio files are, the more RAM is required for this functionality to work properly.

    iTunes/iPod does not provide a way of copying tracks from an iPod to iTunes except for purchased music. But iTunes can play MP3 files without conversion.
    Here are some ways of getting files from an iPod to your PC:
    Copy from iPod to PC
    It is important not to allow your iPod to sync with an empty library. If it is set to synchronise automatically you will get a message saying your iPod is linked to a different library and asking if you want to sync – it is important to press cancel as syncing with an empty library erases all music from your iPod.
    You can also prevent auto sync by holding down shift & ctrl as you plug in your iPod and keeping the keys held down until the iPod appears in iTunes.
    Once you are connected, you need to set your iPod to manage music manually.
    http://support.apple.com/kb/HT1535
    If you have an iPod with iTunes Store purchases on it, you can use it to copy your purchases to other authorized computers.
    http://support.apple.com/kb/HT1848
    However this is not allowed for other music.
    This MacMuse tip tells you how to copy music from your iPod using Windows Explorer, but it is a bit fiddly:
    http://discussions.apple.com/messageview.jspa?messageID=797432
    Otherwise you can use third party software to manage the transfer, there are a variety of programs out there, some free and some that will copy ratings and counts as well as the music files. Here is a selection, check them out and see what suits you.

  • Logic Pro Wont Start Up....  HELP.  Core AUDIO Problems

    OK here goes.. I have been working with Logic since December. I have a lot of project that I am working on and I have this movie sound track that is my biggest thing. Anyway, I have been using logic pro 8 with my Motu Ultralite. Its been working just fine. I got a Mbox yesterday because one of the producers I am working with on this movie uses protools so I got the Mbox to work in Protools 08. I finished my session in Logic...> hooked up the Mbox and tested it out with Protools 8. It worked fine. Now today I tried to launch logic and it would not open. It gets to "initiallizing Core audio" and then it crashes and quits. Can someone help me on this one. I have a deadline to meet today and I have the finished project and cant access my Logic. I am going crazy seriously. Can anyone help. I have did the if You need a crash report I will post one here. PLEASE HELP!!!!
    PJ

    Ive been using Logic 8 and FirePod for some time now and this semester enrolled in a Pro tools 8 class at Foothill using my Mbox. Things seems to be working with both logic and protools, so far other than exporting my sessions over to OMF format, mainly a vanilla import, no effects, automation, etc gets thru, but I digress....
    Check to make sure that your system still see's the Motu device in the system profiler, and open the system log inside the console application within the Utilities folder and then watch what gets reported to the console while firing up Logic.
    To get more help, include what os version your running and the hardware; Mac Pro, Macbook, etc... Stating the version of the programs, and of course have you applied system updates on the your machine....
    Im running a Mac Pro Intel with 10.5.6 with all the latest updates......

  • Core Audio Disk too slow or System Overload message

    Hi, I hope somebody can help me. I've seen the topics about this already posted, but my situation is a little different. I'm only playing back three tracks of recorded audio and two EXS24 sampler instruments. I have the Logic compressor on my bass track and thats it! My Disk IO meter shows no load at all as well as the audio meter. However, I'm still getting the core audio disk to slow or system overload message. I figure with a dual 2.7 G5 and 2.5 Gigs of ram I should be unstoppable. What's happening?
    By the way I'm using Logic Pro 7.1, and my sound card is a Delta 1010 from M-Audio.
