True, what you loose to digital sample rate, you can't get back.  Thanks for 
pointing that out Garry. I misstated what was happening.

When I recorded the audio from the .flv file with audacity it was at the 
default 44.1K (CD quality) sample rate for Audacity. When I exported it to 
mp3 and then reimported the mp3 file Audacity reported a 44,100 sample rate 
for the mp3 file.

When I used MediaCoder to convert the Audio from the flv file to an mp3 and 
then imported it into Audacity, it reported a 22,050 sample rate. When I 
checked the original flv file I noticed that it was a 22,050 sample rate.

The moral of the story. MediaCoder transcoded it at the original rate. 
Audacity recorded at a higher rate, and saved it that way. Anyone examining 
the file created by Audacity might think that it turned the low fidelity 
audio of the flv file into CD quality audio. As you say, it didn't actually 
enhance the quality, it can't. Since I started with something less than CD 
quality (streaming video with audio), that is the best that I can get back, 
no matter what it appears to be when done.

Peace and music,
Dave
