Anybody know an easy way to adjust audio level of recordings made in Asterisk (using the 'record' application)? I've noticed that recordings using the "wav" format are about twice the level of those made using "WAV" or "wav49". Unfortunately, the "wav" recordings are uncompressed and about 10 times the size of the other formats. -brian
Brian Take a look at sox (type man sox at the command prompt if sox it installed for details on the options available). There is a "vol" argument that allows you to adjust the gain. If this is what you need, you can call sox after record (using the system command) to adjust the gain.

Compressed files have smaller bytes, so they are quieter than the uncompressed variety. :-) -A.
