pitch vs playback rate
Let's say I have an audio sample, whose pitch is known to be C4 (don't wanna go in detail here, let's say I just sampled a tuned piano playing the C4 key).
The rules of the game are: I can only ...

Can you increase frequency resolution of FFT without increasing window size?
I'd like to use STFT for multipitch analysis.
I realise detecting the partials existing in the signal is just the beginning.
Still I have problem with it.
Let's say I have signal sampled with 'CD' ...
