I am working on an implementation for managing thousands of IVR within an organization.  Right now, I am storing all audio files in wav format, but it quickly become unmanagable because the size of these wav files ( 8 bits mono ) quickly consuming a lot of the disk space.
 
Is there anyway I can store those audio files and still have high quality audio for IVR?  I know mp3 is smaller but freeswitch does not support it.
 
any ideas?

FS support recording to mp3 directly through mod_shout but you might not want to use that for performance reason.

You can use lame to convert .wav to .mp3 regularly( by crontab if you on linux) or immediately after record(by using iwatch, or listening to event socket to see when the record is done ).

MP3 is NOT recommend and if WAV files are too large you can mosey on
down to the local Best Buy and snag 1.5TB of disk for like $119
dollars. Disk is cheap.

Why is not recommended?

Lets see... mp3 decoding is heavy compared to wav files.. its 2009 and disk is cheap and fast why worry about it? Not sure you wanna scale mp3 playback to the same level you can wav files.

I see, does Ogg/Vorbis have the same problem?

Yes... Why add layers of bullshit on top of audio that is going to
traverse the public phone network? PCM raw or ulaw/alaw are the most
optimal formats.

also, you can store files in PCMA/PCMU format and avoid transcoding at all... and as said disk space is cheap.. go get some...

agree that WAV/PCMA/PCMU formats are best for performance. you can use mp3/ogg ONLY to archive recorded files.
