Thanks - do you know the bit rate? I'm trying to play these prompts with other voice application software, and so far have been unable to. I've tried: Windows Media player, Vox Studio, Envox prompt editor - no luck with any of these. Cheers Scott Scott M. Stingel Emerging Voice Technology Inc.

RE: [Asterisk-Users] .gsm voice format
Use sox to put it is MSGSM and a RIFF header on it. sox file.gsm -g file.wav You need to do this because gsm takes 160 samples and compresses it to 32.5 bytes. On unix systems, they let the half byte go to waste. On windows they slide a second frame down a half byte and combine it with a first frame to put 2 frames into 65 bytes.

RE: [Asterisk-Users] .gsm voice format
Ok, thanks. I should have asked this in the first place: what I'm really getting at is that I need to record (or convert) prompts in many languages. I have a number of Windows based tools to do this. I want to end up with prompts that asterisk can play with the least CPU effort, ie. without transcoding. Would this be the gsm format? If so, it sounds like I should record in Wav format, 8-bit samples? How to convert to gsm? Thanks again! Scott Scott M. Stingel Emerging Voice Technology Inc.

Next record at 8bit 8k so that what you hear on the speakers is the same as what will go out to the phone. Then realize that if you record via PCM and let sox convert to whatever you like, you will be well off. The question about transcoding, if you are going to PSTN via a hardware interface, then you might want to store your audio in alaw or ulaw format, if it is VoIP then whatever codec you might use there, or again alaw/ulaw so it is a one hop conversion. -- Steven Critchfield <[EMAIL PROTECTED]> ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users

Yes, just run through the prompts directory and let sox convert them. You may wish to pull the gsm copies to make sure the wqv copies are used. > - Original Message - > From: "Steven Critchfield" <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Sent: Monday, July 14, 2003 6:10 PM > Subject: RE: [Asterisk-Users] .gsm voice format > > > > On Mon, 2003-07-14 at 09:47, Scott Stingel wrote: > > > Ok, thanks. > > > > > > I should have asked this in the first place: what I'm really getting at > is > > > that I need to record (or convert) prompts in many languages.
