It is significantly slower than the other options, but that is irrelevant here. So try: sox in.wav -r 8000 out.gsm polyphase Use out.sl for a slinear file (then rename it to whatever.snl), out.ul for a mu-law file, out.al for an alaw file, etc. Cf show file formats at the * cli. If you are mostly sending the audio out over a zap channel, you may as well use ulaw or alaw -- whichever the pstn in your area uses. If primarily voip, you can match whichever codec you use or just make it slinear (.sw in sox; .sln for *) and convert it on the fly. -JimC _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
