I have a soundtrack in a project and I need to fade it in and out at two points. When I rendered out a test clip I could still here the track in the places where the audio is panned to zero (-48db). It is very faint but loud enough to hear under the music. Any fix. Thanks.
First of all, AE is a lousy sound editor. Second, make sure that you are adjusting all channels and go all the way -48. make shure you don't have a copy of the layer with your audio track somewhere else in your comp.
I do all of my sound eding in another app.
What Rick said. You may have a duplicate track in a pre-comp somewhere that you used as reference. And Rick again has a point in doing this in an audio app. You could e.g. open your clip via Dynamic Link in Soundbooth/ Audion or Premiere and do your audio mixing there.
