Honored Contributor --- Quote Start --- is it possible that some of your FFT input data is silence until the wave file actually plays? that would explain why the amplitude varies below your threshold. --- Quote End --- Well yes. I can't start the FFT and the wave file at the same time. I have to start the FFT first, and so the FFT is reading silence input before I play the wave file. If I can't do this then what am I supposed to do?
