[Hidden-tech] improved audio for videos

[Bram Moreinis]

Audacity is open source audio editing software for Windows and Mac.  
Separate the audio from the video track in Camtasia, edit it in 
Audacity, then re-import it.

One great plugin for Audacity is Chris' dynamic compressor: audacity 
filter to improve audio quality.  Here's a good sequence to follow for 
audio editing in Audacity:

 1. First normalize (filter) to reduce distortion.
 2. Then remove ambient noises:  select quiet spot, choose noise
    reduction, pick get noise profile, then go back to noise reduction
    and press ok and it will flatten.
 3. Run Chris' Dynamic Compressor.
