[Techtalk] Compressing ogg file

[Alvin Goats]

You obviously have the ogg libraries installed, so use sox! I don't have 
time to trace all of the flags to use (gotta go to work), but...

general defaults these days for sound encoding is stereo, 44100 samples, 
16 bit sound (CD Quality).

Reducing this to mono (1 channel or -c 1 , a flag I remember) will 
nearly halve the size of the file.

Reducing the file to 22050 samples and 8 bit gets you a very acceptable 
quality sound (the original SoundBlaster, pre SoundBlaster Pro), with 
each setting nearly cutting the file size in half.

You have a potential of getting your sound file squashed down to 
something around 8MB. As I recall, sampling 11000 at mono is quite 
acceptable...  check the sound how-to about other settings that give 
acceptable results.
