How do you export 24-bit audio from FCP?

    I cannot seem to figure out how to export mono 24-bit audio from final cut pro (4.5). I tried Audio to AIFF... and tried exporting via Compressor. Either I only get to choose between 8-bit and 16-bit or it ends up as a stereo file. Any ideas?

    Control-click on the sequence you're using for the audio, and select "Settings". You'll then be able to set the bit depth and stereo/mono for the sequence. Then just export the sequence -- you won't have to change the settings in the export window.

    Thanks, I didn't really know that. What I was trying to do was this:

    I have a stereo mix (16-bit/48k) and a 5.1 mix (6 ch. 24bit/48k) that I synced to video in FCP, then edited the video/audio together. When that was done I wanted to export each audio track as a mono file for AC3 encoding. What I ended up doing was exporting 3 tracks at a time to an OMF file (2GB limit) and dealing with it in Digital Performer. I will try your suggestion next time. It would be great if you could just bounce to individual files.

    Wouldn't it be easier to edit to the stereo track, export a 320x188 .mov to DP then edit the 5.1 to the edited video, then bounce as per normal?

    I do this in ProTools fairly often, saves all the hassle of trying to deal with 5.1 in FCP.

    It's quite simple.

    1) Export > Using Quicktime Conversion
    2) Choose your format (AIFF, WAVE, etc.)
    3) Select Options
    4) Change Channels to Mono, Set Sample Size to 24 bits
    5) Save.

    That's it!
