Guest JohnP Report post Posted 12/09/2003 06:25 PM I have set up VoiceGuide (using ComISDN) on an AVM C2 card on Windows XP. Even though I have chosen a sample rate of 8000, 16 bits and mono, and saved in A-law format, the quality of the playback is very bad. I am not sure where to go from here to test. What should I do next? I have tried a different sample rate but Voiceguide will not play them. Cheers, John Share this post Link to post

The WAV files themselves should not be recorded in A-law. They should be recorded in normal PCM (8000, 16 bits and mono) - you can then set the card whether you wish them to be sent over the line in A-law or u-law... Have you tried playing any of the default sound files which came with VoiceGuide? ie: the ones that are installed in VoiceGuide’s \system\voice\ subdirectory... Share this post Link to post
Guest JohnP Report post Posted 12/11/2003 01:00 AM Thanks, I have resolved the issue; I had changed the mode from A-law to u-law (or the other way around!) but had not restarted the PC; this is important when using ComISDN it seems. Share this post Link to post
