[nfbcs] Improving Audio

[Joe Orozco]

Man, I'd completely forgotten about converting MP3 to Wav and back.  Never
mind.  Were it a handful of files I would dedicate the time, but when we're
talking about six hundred or so?  At any rate, does anyone know where one
can find scripts for SoundForge?

Joe,
I'm happy to ssee what I can do to help you out. I have 
goldwave which can probably do at least some of what you want. 
I need to get some info from you before we get started though.

First, what format are your sounds in? If they are in a lossy 
format, such as mp3 or ogg vorbis, it is probably a bad idea to 
try editing them. The reason is that in order to edit them, you 
must first decode to a lossless format like wav, make the 
changes, then reencode in the original format. This will happen 
even if sound forge or other software doesn't tell you it is 
happening, as mp3 and other formats like it can not be 
manipulated directly other than to do basic stuff like change 
tags. My point is, you'll likely have an additional quality 
loss owing to the re-encoding process.

If the sounds are in a lossless format like flac or wav, then I 
would need to know the attributes of the sounds. sample rate, 
number of channels, etc. The thing you have to understand is 
that while it is possible to manipulate a sound to remove 
artifacts, change volumes, etc., thereby improving the quality 
to an extent, you can't improve quality by doing things like 
resampling at a higher rate or adding additional channels. If 
the information wasn't there to begin with, you can't place it 
there obviously.
