I would like to edit and save some wav files so that they can be used as voice prompts.
If you order a prompt from “Allison” Digium provides several file formats, the one that works is a 16-bit 8khz PCM (wav).
I can open this in Audacity, edit it and export it as a WAV (Microsoft) signed 16 bit PCM file and it will play properly.
However if I take a Stereo Wav file, change the rate to 8khz (then speed it up by 451% to compensate), export it the same, it does not play.
Does anyone know how to convert a 44100 wav with Audacity to be used with Asterisk?
or using some other program?
