Question on supported audio input sampling rate

Hi,
I have USB capture device which supports HDMI input and I wish to use it to connect to my digicam and stream it out with FMLE. While I can see that the video input is working properly, the audio is not working. The error message "Problem with audio capture device - Please verify that the audio device is working correctly and is not already in use." always appear when I try to select the device's audio device. Using the graphedit, I can see that the capture device's audio output pin only supports stereo 16-bit 48 kHz PCM output. As such, can I confirm that that FMLE only support 44.1kHz (as well as other 44.1kHz divisible) sampling rate?
Thanks
John

After researching and playing with the system,  I found a solution.  Uninstalling the "Realtek High Definition Audio Driver" under the Control Panel -> Hardware and Sound enables sampling rate up to 384KHz  instead of 48KHz.
If there are other solutions without uninstalling the HD audio driver,  please post.  Thanks

  • How to force digital input sample rate?

    Does anyone know how to force a Digital Input sample rate and/or tell Core Audio which conversion clock to use... internal or external? Apparently both things can be done from Pro Tools, but I don't have it.  My problem is locking onto an A/D converter's 48K Toslink output.  I can set 48K in 'Audio - Midi' setup and the audio is perfect, but a few seconds later  Core Audio returns to the default 44.1K.  I need to force it to stay at 48K, or clock on the signal rather than internal clock.

    Braver,
    Let me clarify a few things. First, the 6733 supports correlated digital I/O. This means that the digital operation does not have its own clock. You can correlate the digital operation with the AO clock, which will allow a digital operation up to the max AO rate. You can generate a pulse train with an onboard counter and use that as your digital clock source. Also, you can use a completely external clock source to achieve the max digital rate of 10MHz. The knowledge base, linked below, points you to a couple of examples that ship with LabVIEW. Be sure and read the documentation associated with each example.

  • Core audio and sample rate conversion

    I would like to know how to take manual control over core audio regarding sample rate destruct... er conversion. First - I know the workarounds - simply closing the audio player of choice, resetting the external hardware and relaunching the audio player of choice.
    setup:
    I run external converters with an external sample rate clock source. No problems or issues here. I keep my music collection segregated by SR (96k, 88.2k, 48k, 44.1k) as I ALWAYS listen through external converters.
    The annoyance is when one forgets to keep track of core audio and inadvertently ends up listen to a piece of music sample rate destructed. You know - walk up to music server computer, forget that you had DAC set to 44.1k for last music played, put on 96k source, SRC takes over and you don't notice the artifacts and distortion for a few songs. No one wants that! Don't get me wrong - it's a convenient feature and the amateur user would be sunk without it.
    What I want is an indicator that will tell when SRC is turned on and further, what the input and output sample rates are (as far as core audio is able to determine from the hardware anyway). In my world this would have been a check box in a preference setting. Perhaps someone has written a script or app for this? Command line instruction?
    Thanks

  • Anyway to force a Digital Input sample rate?

    I've tried three different A/D converters and all fail on the Mac Pro, but work with other equipment. All of the A/D converters have a fixed 48k output sample rate. I can set a 48k sample rate on the Mac and the sound's great.  Unfortunately, it only holds this setting for a few seconds, then snaps back to a 44.1k sample rate and says 'locked'. The audio is then slow and distorted.. like playing a 45 rrmp record at 33 1/3 rpm.  My question is, is there any way I can stop OSX from falling back to 44.1k; i.e. force it to hold the 48k sample rate?

    Got an updated Core Audio driver from Digidesign - that fixed it.

  • DIgital audio in sample rates, 441 48 96 but no 882... is there a way to ad

    When feeding my macbookpro a digital audio signal via optical cable while viewing the audio midi setup utility, it shows that the mbp's internal clock automatically switches to the incoming sample rate. I got it to work with 441,48 and 96k. When I fead it the 882 sample rate it automatically switches back to the mbp's internal clock and reverts to line input instead of digital. So the audio midi setup utility shows when it is in digital input mode the three sample rates 441,48 and 96k in the format pop up window and not 882 so it must be just a software issue and I am wondering if there is a way to add the sample rate to the list. If it can take in 96k it should also be ale to take in 882. So does anyone know how you could ad a sample rate of 882 to the list in the audio midi utility format list?

    One added note. The reason that I want to be able to do this is I like to record my audio projects at 882 and if the mac book pro could except the sample rate I could then use it as a 882 digital 2 track recorder. Enabling me to skip hitting the bounce to disk function in pro tools and actually be able to ride a fader as the mix is printing to the macbookpro, where as when you bounce to disk in pro tools you cannot access the mix as it bounces to disk.

  • Audio problem ( sample rate/ mismatch samplerate )

    Hi everyone,
    I'm using a Macbook white Mid 2010, everything is fine but recenly i bought a USB interface to record music from my instruments ( Mic and guitar ) through garageband..
    I have watched steps on how to connect guitar to garageband, and i did those steps by selecting USB channel as input..
    The problem is every time i test my guitar or microphone, it sounds terrible just like little chipmunk or something. Some ppl told me my sample rate is mismatch. I also was checking around on Audio Midi Setup, i can't change my sample rate for my USB audio interface. The input for it, is 28000KHz, and i was told garageband only accepts 44000KHz.. So i thought my USB interface was having a problem..
    However today i have tested my microphone on my old iMac white, i did plug in my USB interface and microphone, it worked so fine. The sound was not like on my macbook. it just fine and very clear. So my USB interface is not the problem..
    BTW audacity also works fine on my macbook, only garageband..
    Could someone help me? I can give you more details about it..

    Canon cameras are notorious for recording with nonstandard sampling.   Usually, though, material will capture without synch problems. 
    Make sure you have "abort capture on dropped frames" and "create new clip on timecode break" enabled in fcp:  user preferences:  general  and do not capture over a control track break (where you see just "noise" in the video

  • Problems with audio Parallels sample rate

    Hi!
    I recently I installed Finale 2014 in my iMac (Os X 10.9.2) and, when I try to run the application, I receive an error message telling that I must adjust my audio sample rate to 44.1 kHz and Finale crashes. So, by going to Applications --> Utillities --> Audio and MIDI Setup, I adjusted the sample rate to this value and the issue continues to appear. By contacting Finale support, they told me that I must remove my audio device from Parallels Desktop 9 (I was not allowed to adjust this device). But, the problem is that I simply can not remove the device - when I select the device, the " - " signal is in gray. How can I remove the device, in this case?
    Thank you!

    Hello!, first of all thanks for your reply. Yes, the camera is the same, the problem is on my computer, I have discovered a solution: first I capture the audio, only the audio, and then the video, only the video. After this I soncronize the two separate files on Final Cut timeline. It´s a slow process, but I am really desesperated. I don´t know what happens, I few minutes ago I have captured a 30 mins. video and the sample rate of the audio was 42.145k (???). It´s a crazy thing...

  • Audio/Midi sample rates

    Hello, I am new to Logic/DAW recording so please forgive this "newbe" question.
    I was getting an error "while trying to synchronize audio and midi" after installing an audio loop.
    I found that the "fix" was to go into the settings>audio>samplerate>48K
    Fine, the error message stopped.
    But, does this mean that if I wish to use the audio samples in Logic8, I must use the 48K sample rate for the whole project? Or can I use a higher sample rate for live audio (ie 96K) and use the L8 samples at the same time?
    Thanks for any help you may offer, Brian.

    Hi, and Welcome to the forum
    instead of changing the sample rate of your song to match your loops, change the sample rate of your loops to match the song. Read pages 143-145 of the manual

  • How does Core Audio set sample rate?

    When I play a particular movie in QuickTime, the audio and video are out of sync. The movie plays fine on other computers.
    This Mac Pro (OS 10.6.8) is used exclusively for Pro Tools and Final Cut Pro. The audio hardware is a Pro Tools HD Native card:
    Native card --> Pro Tools Digital I/O boxes --> Lavry D/A converters --> monitors
    The sample rate of the Digital I/O boxes is set by an external master clock, a Lavry Gold A/D converter.
    I opened the DigiDesign Core Audio Manager and it says:
    Connected @ 44.1K, 32 In/32 Out, Buffer Size 512
    Yet the movie is at 48K (I know because I created it in Final Cut Pro), and the external clock is set at 48K. So, I don't know where the 41K in the Digidesign Core Audio Manager came from. This is why I am guessing the problem is sample rate.
    Please help me understand what sets the sample rate.
    Does the application using Core Audio set it?
    If so, how is this made consistent with the sample rate set for the hardware by the external master clock?
    Do I have to be sure I always change the external clock setting to be consistent with the movie being played?
    BTW, I have not had a sync problem when I play video in Final Cut Pro..........it is always in sync. So, I have never worried about how Core Audio works. The sync problem is only with QuickTime.

    Well, here is more information:
    - I reinstalled QuickTime 7 and did many other things (trashed preferences,etc)
    - I set the audio hardware (Pro Tools/HD Native card) to 48k
    - I checked the Digi CoreAudio Manager and it said "Connected at 44.1K", even though the hardware was set to 48K
    - I played the problem videos, and all are now in sync
    - I check the Digi CoreAudio Manager and it still says 44.1K
    - I checked the hardware and it is now set to 44.1K
    I know that the videos are 48K, because I created them in Final Cut Pro X.
    Does this mean that QuickTime 7 always converts videos to 44.1K, regardless of their sample rate?

  • Imported Audio Not Sample Rate Converted?

    I received some audio files for a project that were accidentally sent at 48k instead of the 44.1 I need.
    Isn't Logic supposed to automatically do the sample rate conversion if you have the little settings box ticked for "convert sample rates for imported audio"?
    I can't get it to work. I use the audio bin "add audio files", and import the 48k files. They get imported, but remain at 48k, unchanged, after import.
    Is this another bug or is there some part of the process I'm missing?

  • Q: Convert audio bit & sample rate during import

    I have a project that's in 24bit/48KHz, and want to import an audio file (mp3) that's in 16bit/44.1KHz.
    When I import the mp3 file into the project either through drag & drop or the Add Audio File dialog box, it doesn't convert the file into the project's native bit & sample rate. Consequently, when I play it back in the Arrange window it plays in chipmunk voice.
    I thought Logic used to automatically convert audio files into native resolution. How do I do this in Logic 8?
    Thanks,
    Steven

    Thanks for the response. My project currently does have those options checked, and it's still not converting.
    To double check, the mp3 file does get copied to the project's Audio Files directory. It also creates a file with the same name and the file extension .ovw - but doesn't seem to be converted.
    Any ideas? Thanks again -

  • Blue lines through audio, NOT sampling rate

    Hello,
    A friend is editing some audio, using a lot of tracks (around twenty) and shifting the speed. For some reason audio clips that were slowed to 80 percent are appearing with a blue line through them and playing at a very low volume. I checked the sampling rate and it's 48kHz. Also frustrating is that these playback issues are intermittent.
    Any suggestions would be great.
    thanks,
    jesse

    He probably doesn't have the CPU horsepower to render twenty audio tracks on the fly. In User Preferences, you can do a few things to reduce the need to render audio:
    a: increase the number of tracks for 'Realtime Playback' - the default is 8 I think, and it can usually handle more;
    b. reduce the audio quality to low - it really doesn't sound bad at all, and it only affects your preview audio;

  • Audio capture sample rate

    I have read other posts that deal with the issue audio rate that cause the synch with the picture to be off. I recorded this Dv at sp speed and the camera is a pd 150 that had the audio rate set to 32khz. I haved looked in the settings and there is no 32 khz option and you can't make one by copying the generic template. I remember in version four and prior versions that there was the template for 32khz and now its gone, why? How do you get Final Cut Pro 5 to allow 32khz 2 channel sound?

    First, it is better to record at 48k for a lot of reasons. However, go to your capture presets, duplicate the appropriate preset and look at the quicktime audio format options. You should be able to change it to 32k. I can.

  • Any suggestions for Xilinx products to support audio input or touch screens?

    Hi,
    My boss just told me that I will get some funding from our department for new equipment purchase. We want to spend the money on Xilinx FPGA and tool kit.
    We already have a ML605 evaluation board in our lab. Currently, we just make it  communicate with PC with UART cable, but we want to have better demonstrations in the future.
    (1) We want to use a microphone to record speech signals during real time and send the audio signals to FPGA;
    (2) We want to have a touch screen for users to write on, and the handwritten images will be send to the FPGA;
    (3) Any suggestions for fancier demonstration? Video detection or robots?
    For (1), maybe it is possible to just use ML605. But I heard something called "FMC card". So any suggestions on such products;
    For (2), what kind of boards or cards should we purchase?
    Also important,  we can also buy a new evaluation board with Virtex-7, if such boards already support (1) and (2).
    Any suggestions will be appreciated :-)
