Callback data format

Hi there,
If you need to run your other command every time a new utterance is detected you can use -C option in the command line:

auditok [args] -C "sox -t raw -r 16000 -c 1 -b 16 -e signed $ -r 16000 -b 16 audio.wav ; your_command audio.wav"

This will call sox (which you need to install) to write audio data as a wav file (named audio.wav) then call your external program, giving it audio.wav as an argument.

Note that the first -r option in the sox command refers to you input data, hence it can have a different value (e.g., 32000, 44100, etc., anyway this must be your the sampling rate of your input data) whereas the the second -r is used for your output file and should be what you application expects (here 16000 but it can be another value). The second -b however must always be 16 as you want your wav file to be 16-bit.
