Many thanks

]]>If you want no overlap, your hopsize should be the same as the frame size.

aa

]]>if you have an overlap of 2 then 50% of the samples are re-analysed next time (and calcluation happens every fftsize/2)

if you have an overlap of 4 then 75% of the samples are re-analysed next time (and calcluation happens every fftsize/4)

if you have an overlap of 8 then 87.5% of the samples are re-analysed next time (and calcluation happens every fftsize/8)

so

if you have an overlap of 1 then 0% of the samples are re-analysed next time (and calcluation happens every fftsize)

And one more thing you probably need to know that is not written in any documentation – the sample rate inside pfft~ is overlap times bigger as defined in your MSP status due to the fact, that there is overlap times more information to process.

I never did an external in my life but probably such an information is useful…?
