You might want to look into the PipeWave tools: http://www.cardiff.ac.uk/psych/home2/CullingJ/pipewave.html The tools can generate a FFT (fast-fourier transform) of a wav file which converts the data into the frequency domain, which should allow you to tell if a certain frequency is present. -- James > > Jerry -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
