Not quite true. (I'm not an expert in this field, so if you are, please correct me.) Some (most?) file formats contain headers that describe the contents. For example, the WAV file format contains a header (metadata) that describes the endian-ness, the encoding, the sample size, the number of channels and the sample rate. An MP4 file format header would include frame rate, frame width height, duration, number of audio streams, etc. This is how the file command works. But, the original question is improperly formed. Think of the file format as the envelope and the data (the audio) the letter within the envelope. As long as the sender formats the metadata on the envelope correctly, the USPS can deliver it. If the letter is written in French, it will be useless to me as a mono-lingual American. In the same way, I doubt Asterisk is not reading the envelope, I suspect the OP does not know which language Asterisk understands. Asterisk supports at least 2 encodings in a WAV file -- gsm and pcm. I suspect the OP is interested in how to format pcm correctly. In sox (my tool of choice), the command line options -c 1 -s -w -r 8000 will do the trick. To save you a trip to the man page, these are: -c 1-- mono -s -- signed linear -w -- 16 bit words -r 8000 -- 8000 samples per second Audacity should have appropriate check-boxes somewhere in the export menu item. -- Thanks in advance, - Steve Edwards sedwa...@sedwards.com Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000 -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

What sort of options does audacity give you for wave files? r...@missy:/usr/share/asterisk/sounds/en# file /tmp/test.wav /tmp/test.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 8000 Hz Try to match that.
