Re: [Asterisk-Users] Audio level in compressed wav files
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. -brian Bill Seddon wrote: 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. I hope that is meant as funny. In truth the plain WAV format bit shifts the audio up before storage and bit shifts down before playing. No other format does that. Look to the code for true guidance. -- Steven Critchfield [EMAIL PROTECTED] ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
