Missing Audio
I have a completed FCP 4.5 project that I have exported as a QT movie, no problem. I also need to export it for audio only to CD. What is the best quality audio format for CD? AIF?
Problem – I have tried exporting the audio as a AIF, Mpeg 4, etc. and one section of voice audio is missing from the project. It happens to be a section that I took into Soundtrack Pro for modifying
Where the voice section should be, the music bed is slightly garbled. Any ideas and thanks in advance.

An .aif file is what you want for a CD. Down convert your .aif file from 48Khz to 44.1 Khz before you burn your audio to your CD. 44.1Khz .aif is the CD standard. You can do this little job using iTunes.

Try exporting your Final Cut Pro audio tracks as a stereo self contained QT file. Import that into Soundtrack and make your mods. Do a “Save As” in Soundtrack with a different name. Call it “My Project_mod” or something, just to differentiate it from the original unaltered file. Import your new file into FCP, sync it with your original tracks then mute all the original tracks, leaving only the modified stereo track. Then you can export the audio along with your video, or whatever else you need to do with it.
If you have a problem trying to find your missing voice audio you can always drag your source tape from the browser into a new track in the timeline.
Hope this solves things for you.

Hi Don,
Thank you for your help. Your solution worked on the missing audio, but another problem has arisen. I burn the AIFaudio program to CD, but it does not play on a good old CD player. Plays fine on the Mac, but no CD players. Acts like it isn’t even there.Do you have a recommendation on this and also which setting do you use in the AIF options in QT conversion, like Linear PCM, (currently selected) or
A-Law 2:1
IMA 4:1
MACE 3:1
Mace 6:1
Q Design Music 2
Qualcom Pure Voice

Thanks again for your help.

Thanks again.

Glad my suggestions worked for you.
If I want to convert .aif audio to different sample rates in iTunes I don’t really have a favourite setting, but just set the conversion rates for what I need to do at the time.
I use a lot of royalty free music that I buy online. It always comes in @ 44.1Khz so I need to up-convert to 48Khz for use in FCP. In iTunes go to Preferences>Advanced>Importing and choose AIF Encoder. In the drop down menu choose Custom instead of automatic and in the 3 resulting fields choose 48Khz, 16bit and lastly, Stereo. Then everytime you want to export a 44.1Khz file from iTunes it will use those settings.
If you want to take 48Khz audio from FCP for use on a CD then you export audio only from FCP, bring that into iTunes and export with the .AIF Encoder settings of 44.1Khz 16bit Stereo, which is the CD standard.
Hope this helps.
– Don
