I was interested in other peoples experiences: We run a conference bridge (meetme) and want to record calls. we will need to have those files in MP3 format eventually.
Out of the box and Debian/Asterisk box doen not support MP3 encoding. right now we encode to wav files, transfer these to our windows servers and convert them to MP3 there. but this seems cumbersome.
I would like your opinions on:
[ul][li]what is the best format to record to in Asterisk (WAV, SLN, GSM, etc). I’m interested in quality of the recording and very much in the overal impact to the system performance.[/li]
[li]working with MP3 on asterisk machines. what is the best way to convert files to MP3, which libraries to use for that (examples?) and what is the impact on system performance when converting to MP3?[/li][/ul]
