Converting recorded sound

[brent.russell]

I noticed that when I record a 2 minute message and post it to my server, it is only 60-300 kilobytes! I am developing an application that will accept mp3's from people and they will be used as voice prompts in an IVR system. However, the average user does not know anything about compression of sound files so I need to do this for them. Can you tell me how your system is compressing these sound files? Is it being done in TCL or is is being done by a Cisco box or do you have a command line program such as Sox that converts sound files to a small file size?

I need to do this programatically on my side and not with a simple win 32bit GUI program. I realize this is not your area but maybee you can provide som insite on how your server is doing it.

Thank you

You can use lame (http://lame.sourceforge.net/index.php) to compress files into MP3 format. It's a powerful and flexible MP3 command-line conversion tool which can run on pretty much any operating system, including IVR.
