Audio input, follow up Q

I was looking at http://www.m-audio.com/products/en_us/AudiophileUSB-main.html
because I've had good results with M-Audio products and their prices are reasonable.
I've got a M-Audio usb for midi input and a PCI card for both midi and audio in/out.
The midi connections on the Audiophile USB and setup in AudioMIDISetup I am familiar with.
However this is my first venture into having to work with usb input for audio.
Looking at the USB Audiophile I think that the analog audio from my mixing board goes to analog audio in of the Audiophile. Now this is were I get a bit unsure: does the audio out of the Audiophile goes to a pair ( L/R ) monitors?

Thanks to your very patient help I finally resolved my misunderstanding about getting the audio in/out.
Therefore there is no need for me to purchas the usb Audiophile.
I can use my Roland VS1680 hard disk recorder's optical in/outs, spifs, or analog. I've never used the optical feature because I never had an device that would accept optical audio data. Now I can use it with my iMac.
I use the VS1680 not only as a hard disk recorder but also as a mixing board.
I certainly appreciate all your help and especially staying with me here.

  • How can I get my audio input and output devices back? I have no sound and cannot see any of the devices in Audio MIDI Setup..??

    Hi, I tried to set up a new output audio device on my mac that would have multiple outputs (iBox Twist speaker and my internal speaker) but when I went to click onto one of the iBox Twist (there were 2 options available: iBox Twist and iBox Twist Stereo), Audio MIDI Setup crashed and when I finally got that back open, I found that there were no audio input or output devices to be found. My sound is working, as when I turn on my iMac, the starting sound still plays, however the volume control in the menu bar is no longer a black colour, but grey and when I try to change the sound on my keyboard it does not change. This already happened to me once, and after 3 hours I managed to fix it very simply (switching off Mac, unplugging power cord, leaving for 15 seconds, plug power cord back in and switch Mac back on, holding Alt, Cmd, P and R keys until you hear the Starting Up sound twice) however this same technique that fixed it once before is not working this time and I am still stuck without sound. I have tried Repair Permissions, rebooting in Safe Mode, Hardware Test and checking for Software Updates. Has anyone else had this problem and managed to fix it?
    Thanks in advance for any help anyone can give me!

    In case anyone has had the same problem as me, I have just managed to fix this by doing the following:
    Switch off Mac
    Switch back on in Safe Mode (Hit power button, then hold Shift key until a loading bar appears at the bottom of the screen).
    Switch off Mac again
    Remove power cord and wait 15 seconds
    Plug power cord back in and hold down the keys alt, cmd, p, r all at the same time until you hear Starting chime for a second time and hopefully your audio will back.

  • Macbook Pro, audio input

    I have a Macbook Pro 13". I would like to use the "Headphone" port as a "Microphopne" port and connect to an external audio input source (Mixer in a DJ set-up) and record my mixes. I have followed the instructions listed on various forums to do this but my computer does not give me the option to change from Sound Output to Sound Input under the tab "use audio port for" which can be found under System Preferences/Sound in the Apple drop down menu.  I believe Apple for whatever reason dropped the external mic function on their newer Macbook Pro laptops.  What can I do to fix this ?

    Perhaps this is what you are looking for...

  • Webcam/Audio Input

    I am admittedly an amateur at Actionscript, but I'm trying to
    produce an example of Flash's ability to process video/microphone
    data as a "jumping off" point for other projects. My problem is:
    I am using some open source to pick up web cam movement and
    produce a matrix based on such. I have added the code to receive
    microphone input, which worked in the example (provided at
    kirupa.com) that I composed on my machine. I am trying to replace
    the "dot_mc.1=255" value with the microphone activity value
    (0-100?) yet I am getting a response of "The property being
    referenced does not have the static attribute." I understand this
    statement, but I am unsure as how to re-form this statement to
    accept variable data.
    Here is the code so far:
    import flash.display.*
    import flash.geom.*
    mic = Microphone.get();
    _root.attachAudio(mic);
    mic.setUseEchoSuppression(false);
    function initialize()
    setInterval(this,"snap",100)
    this.createEmptyMovieClip("snap_mc",this.getNextHi
    ghestDepth())
    snap_mc._x=(Stage.width/2)-(scale*w/2)
    snap_mc._y=(Stage.height/2)-(scale*h/2)
    m=new Matrix()
    m.scale((output._xscale/100),(output._yscale/100))
    now=new BitmapData(w,h)
    rt=new Rectangle(0,0,w,h)
    n=0
    for(x=1;x<w;x+=o)
    for(y=1;y<h;y+=o)
    ++n
    dot_mc=snap_mc.createEmptyMovieClip("dot"+n,n)
    dot_mc._x=x*scale
    dot_mc._y=y*scale
    dot_mc.lineStyle(dblo,0x000000)
    dot_mc.lineTo(0,1)
    function snap()
    var c=0
    now.draw(output,m)
    for(var x=1;x<w;x+=o)
    for(var y=1;y<h;y+=o)
    ++c
    nc=now.getPixel(x,y)
    nr=nc>>16&0xff;
    ng=nc>>8&0xff;
    nb=nc&0xff;
    nl=Math.sqrt(nr*nr + ng*ng + nb*nb)
    bc=before.getPixel(x,y)
    br=bc>>16&0xff;
    bg=bc>>8&0xff
    bb=bc&0xff
    bl=Math.sqrt(br*br + bg*bg + bb*bb)
    d=Math.round(Math.abs(bl-nl))
    dot_mc=snap_mc["dot"+c]
    if(d>tolerance)
    dot_mc.clear()
    dot_mc.l=255
    dot_mc.lineStyle(dblo,255<<8)
    dot_mc.lineTo(0,1)
    dot_mc.onEnterFrame=fadePixel
    updateAfterEvent()
    before=now.clone()
    function fadePixel()
    this.clear()
    this.l-=this._parent._parent.ml
    this.lineStyle(this._parent._parent.dblo,this.l<<8 )
    this.lineTo(0,1)
    if(this.l == 0)
    delete this.onEnterFrame
    Altering the dot_mc value varies the colors of the webcam
    matrix dots, so I just need the activity level on the microphone to
    act as the value and perhaps multiply it by 2 (since the dot_mc
    value can be up to 255).
    Any Ideas on how to repair this?

    Thanks for the suggestions. A few hours after posting my issue I switched everything on and all was as before. I could control the audio input level in system preferences and use the webcam for skype calls as before, using it as the audio and video input device.
    Now I have swithched the machine on again and it seems to have reverted back to the same problem as described in my original posting......very frustrating. Nothing registering on the sound input levels in system preferences. Tried restarting several times without success.
    The Midi settings for the "Unknown USB Audio Device" i.e. Webcam are as follows:
    Source Default (Grayed out)
    Format 48000 Hz 1 ch 16 bit
    M Channel volume slider is at the mid point, Value 0.49, dB 18.28, Mute and Thru both unchecked
    I Channel slider grayed out and all else blank.
    Since everything started working again I haven't touched these settings so I assume that they are the same with or without the issue.
    I know issues that occur randomly such as this are least likely to find a solution but further suggestions welcome.

  • Audio input problems

    Hi
    I tried playing in a recording from a Minidisc for editing on Adobe Audition - something I've done many times with Audition on other computers but never with this one.

  • Re: Audio Input latency over 1 second sometimes.....

    This is a BUG in a recent Logic update that I did unfortunately.
    Logic Pro 9 on imac24" had been working flawlessly for many months in my studio.
    Audio from my various synths is going into the iMac via a fader panel via spdiff. Also main synth (Korg Oasys) is also going midi in to the iMac.
    After this recent update from Apple on fresh powerup and Logic started and a Yamaha piano grand selected on Logic and 12String Guitar selected on my Korg Oasys, the following happens.
    When I press say the middle C on the Korg, right away the Yamaha plays the C.
    Then after about 1 second delay, the Guitar sounds.
    Then I quit Logic, then restart Logic and everything works fine till the next time I do a fresh powerup.
    This is very silly to have to go through every single day......
    Anyone have any ideas?
    CPU load always show very low load always.....

    I know that you said earlier that you're using spdif. I asked you for more information about this, because your iMac does not have a standard spdif jack. It does not have a standard toslink jack.

    From apple.com, my iMac has:
    "Audio line in/optical digital audio input (minijack)"
    This is where the Roland Toslink output is plugged into. There is no separate adapter needed. The iMac is able to understand the standard Optical frames via the fibre optic cable. We need to move on from this connection as it works as designed.

    } {quote}
    I apologize in advance if i am not patient enough and i appreciate all the help you guys are offering... but why would you ask about pressing a key on the Caps Lock keyboard? As explained earlier, in addition to generating music from its own sound engine, the Synth supplies the MIDI data straight into the iMac via USB. The iMac sees the synth Keystrokes in perfect realtime and plays whatever instrument I select in Logic...in perfect real time. Its the Analog being generated from the synth engine that gets delayed until I putz with perhaps the .plist file. (read Eriksimon's comment above). In my very first post I explained that I had selected a Yamaha Piano (a Logic Instrument) and a Steel Guitar (An instrument on the Synth) setup. So when I hit a middle C on the Synth, the Logic Instrument Yamaha AND the Synth Instrument Guitar should sound at the same time. But they don't...until I putz with the .plist file. Hope this clarifies the confusion?
    Help me out here Eriksimon. You seem to get what i am faced with.

  • Mac Mini USB Webcam Audio Input

    I purchased a Mac Mini a couple of months ago and set it up with HDMI to HDMI connection to my Samsung TV. I then purchased a Logitech webcam V-UBU48 and connected that to the USB on the Mac Mini. All was fine and I used Skype on this combination with no problems for a couple of weeks, using the webcam as both Audio and Video input device. Sound output was via the TV.
    I then went on leave for a couple of weeks and on return set everything up again as it had been before. This time there is no audio input from the webcam and changing settings in Skype preferences or Midi utility does not seem to have any effect, The webcam is recognised as "Unknown USB Audio Device", but doesnt seem to work. So far as the Mac is concerned the video side recognises it as a Logitech Webcam and still works perfectly. Sound output via the TV is also still fine.
    Since my return the only change that I can identify is the latest Snow Leopard upgrade to 10.6.4
    The other issue is the volume control on the bar at the top of the screen is grayed out and does not function any longer.
    Can anyone help identify the issue here. Thanks in advance

  • Horrible Line Noise w/ Built in Audio Input After Update!

    Something happened after the most recent LE8 update, I now have terrible line level hiss/noises when using the built-in input on my MacBook Pro. No trouble with my Firewire audio input though. The noise is really bad and records to track, making me believe that this is an input issue. I'm not positive that it's from the update but I've never had this problem before. It happens with both Logic Express and Garageband, rendering the audio input useless. Anyone else having this problem?

    Thanks for the response guys. It seems we're in the same boat.
    The problem is intermittent on my machine . It has occurred three times since I bought it. The fist time it lasted for a day and a half. I rang Apple support and went through a number of steps until the P-RAM suggestion which seemed to fix it. A few days later it disappeared again and resetting the P-RAM had no effect. My wife continued to use the computer (without sound) and some hours later it came back after a restart (she only restarted it because she is in the habit of shutting down instead of using sleep). The problem occurred again. That time I restarted the machine a number of times, with and without the external speakers plugged in, with them turned on and off etc. This had no effect. I gave up. Some time later my wife went to use the computer and it came back. I now believe that the P-RAM solution that seemed to fix the problem the first time was just a coincidence.
    I rang Apple support again and they gave me the following steps (A,B & C of which I went through the first time the problem occurred):
    A: Log in through another account and see if it had the same problem.
    - The built-in audio was still missing.
    B: Run the disk utility on the hard drive (after booting from installation DVD).
    - There were nil problems on the HD, but it did not fix the problem.
    C: Reset the P-RAM.
    - This worked the first time though it has not worked on subsequent re-occurrences of the problem.
    D: Do an Archive Reinstall.
    - I did this today; though the built-in audio was working, I just wanted to complete the suggestions the Apple support person gave me. The problem has not reoccurred yet, but it has only been a few hours. I will be using the computer as much as possible tonight to see if the problem reoccurs.
    If the problem reoccurs I'll be taking the machine in for warranty repairs, or better still replacement.

  • All audio input dead -- internal mic, USB mic

    Hey folks, for some reason my iMac G5 suddenly will not recognize any sources of audio input.
    In the Sound pref pane, the "internal microphone" option under the Input tab is not even there anymore. Only line-in.
    In addition, when I check input levels with an external (USB) mic, I get zilch. Otherwise, the USB on this machine works fine, and furthermore this same mic works without a hitch on a G4 Powerbook.
    Since this is happening on two very different hardware channels, it must be a software issue.
    I've tried resetting the system's audio by restarting, running Garage Band, running Audacity, anything I could think of. Nothing works.
    As to what could have triggered this change, three events happened recently around the same time involving audio on this machine: iTunes 10.0.1 update; Rogue Amoeba SoundSource update from 2.0 to 2.5; and a PRAM reset when I recently had all audio output also die. (The PRAM reset fixed the output issue.)
    Any ideas?

  • No audio input or output when connected to bluetooth headset

    I have a MacBook Pro 15" early 2013 (MacBookPro10,1) and a Plantronic Legend.
    Since upgrading to Yosemite (I am not 100% sure it's related, it just didn't happen on Mavericks), I have the following problem: my headset connects to the MacBook correctly, but I don't see it in the sound preference panel, neither under audio input nor under audio output.
    If I open the System Information, I can see the Bluetooth Headset being recognised as such:
         Major Type: Audio
         Minor Type: Headset
    If I reset the SMC and repair the headset, it works again, but that's a hassle.
    Anybody else having the issue and maybe found a better workaround?

    Removing and pairing again the Plantronics Voyager Legend solves the issue. But it keeps on happening again. Really annoying.
    I have firmware v106 for the Plantronics Voyager Legend, which is the latest at the time of writing.

  • Firewire Solo - No Audio input in Logic

    Always there are problems with using live audio input with Logic. Why can't it plug'n'play like Garageband?
    I'm getting no audio input to Logic Pro 8, even thought a signal is going into the 'Solo and into the Mac itself.
    I've done all the following:
    - Installed M-Audio's 1.9.3 driver update for SL
    - Selected the 'Solo in Logic prefs
    - Checked its selected in OS Prefs
    - Unplugged and replugged the 'Solo 'hot'
    - Restarted the Mac
    - Restarted Logic
    Any ideas people?
    I'm right minged-off, as I'd finally time to do some recording this weekend. But sans audio input - no soap.

    Try launching the M-Audio FireWire application and check the software mixer to make sure inputs or outputs aren't muted or turned down. I had that happen once.
    BTW - Although the unit has 6 inputs (mic and instrument on the front, stereo line in on the back and digital coax stereo in), I believe only the two of the four analog inputs can be active at a time. Either the front pair, or the back pair.

  • Audio input gain increases automatically

    I use both skype and google voice (via gmail) for VOIP calls. In both cases, regardless of the client settings (there aren't many for google voice), the system audio input will increase on it's own over the course of a call.
    I've had this issue for years and i've never seen an actual resolution. Stumpped.

    May have found the answer here:

    Plist files in OSX can be of 3 different formats:
    - Binary (just like the one used by com.google.GoogleTalkPluginD.plist
    - XML
    - JSON
    Don't bother editing the binary file (by performing guesstimates, editing with an hexa editor etc); it won't work.
    Instead, perform the following:
    1 - Make a copy of the file to your desktop: cp ~/Library/Preferences/com.google.GoogleTalkPluginD.plist ~/Desktop/
    2 - Convert the Binary Plist to an XML Plist: plutil -convert ~/Desktop/xml1 com.google.GoogleTalkPluginD.plist
    3 - Edit the file with an editor (Aquamacs, TextEdit) and set the Audio Flags value to 1
    4 - Convert the file back to Binary: plutil -convert binary1 ~/Desktop/com.google.GoogleTalkPluginD.plist
    5 - Copy the file back to the Preferences directory: cp ~/Desktop/com.google.GoogleTalkPluginD.plist ~/Library/Preferences/
    6 - REBOOT (closing and reopening the browser won't work as the plugin runs on the background. We "could" kill the process to have it restarted, but we'll leave it simple and reboot the machine).
    That's all it takes. Now feel free to set your mic volume to the value you desire and it will STAY at that level while using Google Talk (it won't auto adjust based on background noise).

  • Stereo line-level analog audio input?

    The analog audio input on my machine seems to be mono only. If I put in a stereo line-level signal it just duplicates the left channel on the right. Is there any way to input a stereo line-level signal through this jack?
    ALFRED GUZZETTI

    The input source is a DV tape deck. At the head of finished tapes I record bars and tone. The first segment of the tone is on both channels. It is followed by tone on the left channel only, then the right channel only. When I monitor what the computer is getting either through headphones or direct the input to Soundtrack Pro, where the meters display left and right, I hear and see sound on both channels from both the stereo input and the left-channel input (which shows up on both channels in the computer). The right channel only input is not audible or visible on the meter. The computer has always been this way. I assumed, maybe wrongly, that the input uses a stereo jack since these are pretty universal, but that in effect, the input is mono.

  • Isight with another audio input?

    I want to record a video with isight but with another audio input other than the built in microphone. I have tried changing the input in preferences - sound - input but that doesnt seem to apply with the audio in photo booth.

    (1) Yes, for many common problems, location really does matter, although I think not for this one.
    (2) Photo Booth is such a simple fun app that it offers few configuration options, although the latest version (Photo Booth 3.x) adds the ability to choose among connected cameras. However, there is still no menu choice that allows you to select among microphones. The only way I know to change mics is to change the system microphone in your Mac's System Preferences... > Sound > Input like you tried to do.
    You do not say what sound input you want to use instead of your MacBook's internal microphone. I have tested my Photo Booth with my Apple LED Display, external iSight, and Logitech Desktop mics. All worked. Testing again after you shut down (not "Restart") your MacBook and then start it up again.
    (3) If you still have trouble, test with QuickTime instead of Photo Booth. QT lets you change the microphone source by clicking QT's Preferences disclosure triangle as shown in this image:
    You Mac's choices will be different than those shown in the image, but any sound input source that is recognized by your Mac will be there. Any mic that works in QT should also work for Photo Booth when selected in your Mac's System Preferences... > Sound > Input. After selecting the mic, say a few words and watch the "Input level:" meter to check whether the mic is working.
    After selecting your other microphone, the blue indicator lights in the sound check "Input level:" meter in Preferences should flicker when you talk. If they do, the mic should also work with Photo Booth.
    (4) If your alternate mic works with QT but still fails with Photo Booth, try resetting your Photo Booth preferences. If you have never done it, here is how:
     • Restart Mac
     • Navigate to the "com.apple.PhotoBooth.plist" file in your Home ( ) > Library > Preferences folder.
       (Be sure you are in the Home Folder preferences folder, not your System's.)
     • Throw the "com.apple.PhotoBooth.plist" file in the Trash
     • Launch PB and test again.
    (5) If the PB problem persists, apply the 10.6.6 Combo Update using the following process:
      • Backup your Mac and turn off Time Machine
      • Disconnect peripherals and restart Mac
      • Use Disk Utility to repair permissions
      • Download and install http://support.apple.com/kb/DL1349
      • Repair permissions again immediately following the restart that finishes the update.
      • Test PB again
     (• Turn Time Machine on again when you are satisfied that the update worked.)

  • Audio Input Error Message

    I have AA3 with a built-in Intel high definition audio card, and its drivers are up to date.
    When I start the program, the following error message appears: "The audio input is not activated. Recording audio is not possible. Please check your configuration."
    I am trying to troubleshoot the problem within the "Audio Hardware Setup" window (see the screenshot below).
    It doesn't matter whether I check or uncheck "Release ASIO Driver in Background," the error message still appears.
    Thanks for any tips on how to further troubleshoot this error message.

    ...and since there's no way you'll get an ASIO driver for an internal sound device, the 'Release ASIO driver' message shouldn't make any difference to anything...
    One thing you might like to try though is the free ASIO4ALL driver, as a replacement for the 'Audition 3.0 Windows Sound' one. This has better diagnostics, and may give you more of a clue about what your sound device isn't doing. Just Google it - it's easy to find.
