Do you know the frequency(ies) of the beep you are looking for? Perhaps
a bank of IIR filters at the beep frequencies would be cheaper than an
FFT, and is more of a continuous processing so it won't have edge
conditions? Or maybe just a simple energy detection, and then do the FFT
when you see
Hi All,
My code is setup to detect regular beeps in a real time buffered
stream of samples from a SDR. For efficiency reasons I perform beep
detection using fft - and if no beeps are detected no further
processing is done.
This works pretty well except for one edge case - where the beep is on
the
