Hello: Thanks for the input so far. Heres the issue-- This is a production environment-- where many people "touch" the files. ie-- The audio engineer is a freelancer who wants to master the files at the highest quality TO HIS EAR and experience-- He knows NADA, Not a thing about SOX-- but is a ProTools GURU. The SOX resampled files work on our asterisk box-- but I gotta put someone else in the loop-- resampling the audio engineers .wav or .aiff files (hes a radio guy who works in .aiff at 44.1-32bit float) Im looking for a solution (software, and prefs) which will take the middle man (and SOX) out of the production loop-- ie the Audio Engineer simply masters and hands off GSM files which will work. I was hoping to find someone who has produced the "correct" gsm files without SOX, on either a MAC or PC. HELP, again, WOULD BE ***GREATLY APPRECIATED*** Cheers- jjq _________________________________________________________________ Looking to buy a house?

That's what I do, actually Apollon Koutlides

Try to get your AE to save them as mono 16bit signed-linear wav files. He should understand that and be able to do so. This will save the decode from gsm step when playing those files. It will also slightly improve the quality when compressing to some other codec. Especially if it is one of the lower bandwidth codecs. (If you are only ever sending the files out over zap channels, the best file format to use is ulaw or alaw as applicable to your area. But that may be as difficult to get from your engineer as gsm.) -JimC -- James H. Cloos, Jr. <cloos@jhcloos.com> <http://jhcloos.com>
Apollon-Stephan/others-- Thanks-- just what the doctor ordered. Well get on those solutions today. Just to complete the thread-- If anyone else has ideas, ie the names of Mac or PC software which produces the "correct" GSM file-- PLEASE POST it to this thread. Also- If anyone has produced the "correct" GSM files from ProTools-- It would be interesting to know the settings-- ProTools-HD has MANY settings which allow you to do custom compression, etc. It would be nice to know how to stay in the ProTools environ to get these ***GSM files*** (as opposed to the .wav solution suggested by Apollon-- which seems like a ***VERY NICE*** solution.) **** I have been told that ProTools WILL NOT sample (or resample) at 8K-- This is a "FEATURE" of their software as they want to only ALLOW High Quality audio masters, and the Rep has told me the 8K samples "sound like crap". (I can not confirm this as I have never seen the HD version of the PT software) THANKS AGAIN.
