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? keith
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 ). 2009/10/3 Keith Wood <keith.wood2000@gmail.com>

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. /b On Oct 3, 2009, at 1:44 AM, Keith Wood wrote:

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. /b On Oct 3, 2009, at 12:07 PM, Diego Viola wrote:

I see, does Ogg/Vorbis have the same problem? Diego On Sat, Oct 3, 2009 at 5:47 PM, Steve Underwood <steveu@coppice.org> wrote:

also, you can store files in PCMA/PCMU format and avoid transcoding at all... and as said disk space is cheap.. go get some... On Sat, Oct 3, 2009 at 7:07 PM, Diego Viola <diego.viola@gmail.com> wrote:

agree that WAV/PCMA/PCMU formats are best for performance. you can use mp3/ogg ONLY to archive recorded files. /nandy On Sun, Oct 4, 2009 at 7:38 AM, Tihomir Culjaga <tculjaga@gmail.com> wrote:
