Weird audio problem! If I have a wav file of an oscillator of, let's say a filter sweep. I know: * Roughtly the frequency of the oscillator (+- 50 cents) * That the recording begins and ends on precisely the same phase How do I quickly count EXACTLY the oscillator cycle count?

I'm just counting how many times the oscillator repeats. Like, a 440hz oscillator playing for a duration of 2 second would count 880 cycles. Here, I don't exactly know the frequency. Only the length of the recording and that it starts/ends on the same phase.

The oscillator waveform changes over time, but the fundamental frequency stays the same. If I precisely knew the frequency, the answer would be length multiplied with the frequency.
