Unfortunately, this doesn't really work out to be a great solution. The dynamic range of the original recording is limited and scaling it after the fact just yields fairly distorted sounding recordings.
It seems like the problem is a bug in the implementation of the compressed file format encoders, or the process by which they get invoked. I guess I'm going to have to dig into the code.

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.

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.
