[Asterisk-Users] <<< GSM AUDIOFiles >>>

[jeff quade]

Hello:

I would like to produce some GSM Prompt audio files for a Telephone 
Directory Project-- and have hired a freelance audio engineer to record, and 
edit the actual files--

However the GSM files he gives me to upload into asterisk DO NOT work when 
played back throgh "Stream File" or "Get Data" in my agi. It seems that 
there may be more than one GSM file type (with header and without, linear 
compressed, quadratically compressed--etc)

I have read this doc-- but we need an answer which DOES NOT USE SOX:

http://www.voip-info.org/tiki-index.php?page=Convert+WAV+audio+files+for+use+in+Asterisk

Can anyone please point me to, or post the correct way to produce a high 
quality, asterisk acceptable, GSM file WITHOUT using SOX?

We will be using PROTOOLS-Mix-Plus, or can use PROTOOLS-HD to produce our 
audio files-- But are looking for ANY Macintosh or PC Audio-Production 
software suggestion , (outside of using SOX) which will take an .aiff or 
.wav file and turn it into a GSM file.

ANY SUGGESTIONS WOULD BE GREATLY APPRECIATED- THANX.

Thanks-
JJQ
