Smoothly Cutting One Audio track to Another

#1

I make screencast movies with a cheap mic and there is base level ‘tape hiss’ in the silence. I don’t mind that. Here’s my question:

How do I cut one shot to another so that the audio is smooth? I want to overlap and crossfade the hissy ‘silences’ so that there is no ‘true silence’ between them. What dB level to I set the audio to to do that? 0 db is not silent. I have to go to like -128 dB to ‘silence’ one side of the cut, and that makes the two tracks crossover at a place that is quieter than it should be.

After :26 seconds here, for example, is such a silence

Umm, you use an (audio) editing program? I’m not sure why’d you even bother with AE, when you could do this with full interactive (!!!) feedback in Soundbooth, Premiere or even Audacity (which is free). Without seeing the source file, I’m afraid this going nowhere, anyway - your atmospheric noise/ static is contained in the setup level, but depending at which master level it was recorded, this could be anything. That aside - 0dB is the master level, not the minimum. The scale is inversed and goes into negative.

Well, then AE should remove the ability to change the dB levels altogether, to make sure no one accidentally gives it any value but 0.

Lets you and me start a letter writing campaign.

I downloaded some pink noise from freesound.org and tried some tests.
