Maybe it’s a stupid question, but haven’t figured it out this morning…

It’s about the bins or the third outlet of fftin~ object (in pfft~).

Say fft size is N, shouldn’t the real FFT have bins all the way from 0 to N/2?

Here fftin~ only gives bins from 0 to N/2-1, missing the highest frequency bin?

Thanks in advance

If it really matters to you you can try the old-school fft~ approach and roll your own overlapping scheme – it’s a bit of a pain. fft~ also only goes up to 4096 points though so you can’t do more than that and keep the nyquist bin. In my experience the number of cases where this will make a difference are very few, and mostly relate to fft processing with no window function….
