I also worry about this, but usually there are much bigger problems
to worry about :-)

Audiograbber has some advanced settings for normalization, but I have yet to
find a program to use a sliding scale (equivalent to your father controlling

Normalization consists of determining the output leven of the audio data,

The trick is twofold: First of all,

But wouldn't a lame-integrated normalization (i.e. scaling of the sample

Hello, all.
I would like to normalize (maxmize) and trim silent part from input audio
data. I'm going to add both routine into get_audio.c (I don't use
libsndfile).
Does anybody know how to do that or such sound libraries?
TIA
