Hi,
I have not really looked at the code, but I noticed that 1440 Hz is pretty close to the Nyquist frequency (1500Hz) for a sampling rate of 3000 samples/second, so perhaps you just have to multiply by 2 the maximum frequency you want to detect.

Indeed Galfodo was correct. This algorithm only detects frequencies up to half of the maxF value, so you need to double that to get the true range.

Thanks for your followup ! Good to know, and intuitive indeed.
