[PD] why overlaps affect frequency of [osc~]?

2013-11-26 Thread Alexandre Torres Porres
Howdy, ever tried to compute a hann window inside a subpatch where the FFT is happening? And then if you're overlapping it by 4, do you see that only 1/4 of the cycle from [osc~] came up? That means the [osc~] frequency was 1/4 what it should be... Now, why and how does it happen? I just have

thanks master well, I was betting it was that, and it actually brings me to more direct questions I should have asked before. So here they go. Simply put: How come and why does overlapping affect the sample rate? the same happens if you raise the samplerate via upsampling. I guess this is

[1] https://sourceforge.net/p/pure-data/feature-requests/16/ Not sure if I got what the request was requesting. the parameter s-s_sr isn't defined properly, as s-s_sr=(fs*overlap) has nothing to do with the actual sampling interval applied to the audio data. Is this bit just saying overlap in

hope this clears things a bit. I can't see how it could be any clear :D thanks so much for the detailed explanation, really appreciate it I finally know how overlapping is actually done behind the scenes now, cool And yeah, objects like [osc~] should totally be aware of this matter and do it
