Audio export problem

[Aharon Rabinowitz]

Are those audio settings your audio output settings, or are those the specs on the audio source file?

If you are using an MP3 as your audio source, convert it to WAV outside of AE. MP3’s casue all sorts of problems in the audio, which you don’t hear until you render.

Also, make sure you don’t have more than one copy of the audio file in your comp, or that other source footage you have in there doesn’t have audio. If they do, and you are not using them, turn off their audio switch in the timeline.

Forgot to say, try it at 44 Khz instead of 48 Khz. See if that helps.

Thanks for your reply!

The answer is: Both.

If you are using an MP3 as your audio source, convert it to WAV outside of AE. MP3’s casue all sorts of problems in the audio, which you don’t hear until you render.

Nope, all audio source files are WAV/16/48

Also, make sure you don’t have more than one copy of the audio file in your comp, or that other source footage you have in there doesn’t have audio. If they do, and you are not using them, turn off their audio switch in the timeline.

Only the needed audio is switched on in the comp. And like I said, the confusing thing is that when I render it mixed into the avi movie, it sounds fine. Then if I export the audio only without changing a single thing in the comp, the sound cracks.
I don’t get it.

Kind regards,
Eric

I have to deliver the exported audio as 48000 kHz.

I have no idea what is causing that.

Here are my makeshift solutions – If they need the audio file for a NLE like final cut, then you can just render out your audio as an AVI with no video. The NLE should have no problem.

If this works, and your sound quality is where it should be, but you absolutely need it as a WAV file, maybe try either re-exporting that new audio file from AE as a WAV, or use a program that can extract audio from an AVI – most audio programs can do this, and Quicktime Pro should be able to convert it for you.

I’m not saying these solutions are ideal, but they’re all I can think of, not being there with you to see the file.

Hope it helps…

Thanks for your suggestions!

Just a thought here:

does the clipped Wav still sound stereo ?
Because if both the left and right channel are played in the center instead of through discrete channels, in theory the sound would go up by 3db.

Just maybe, that’s what’s going on there to result in clipping, but it would be a serious bug in either AE or the program you’re using to listen to the WAVs

Thanks for the tip on checking stereo/mono: It still is stereo. I can preview the audio in the comp before export, and after export it’ll crack even if I import the new file into AE and preview it there! I’m baffled.
