Hi everyone, I started to work with maxmsp and there we had the [pfft~] object that creates the overlaping like [block~] and [switch~] do in a subpatch on PD. I am working very well with PD and spectral processing, but then I had a more theretical doubt: What should be really an overlap? There are two possibilities that I figure:
1: Read continuosly a signal and overlaps on while readin. example: Imagine two 8-sample signal vectors on loop with these values: (0 0.125 0.25 0.375 0.5 0.625 0.75 0.875) (1 0.66 0.33 0 1 0.66 0.33 0)
These signal should be read on a subpatch with [block~ 8 2 1]. If it were read continuosly I would have for which element of the overlap: (0 0.125 0.25 0.375 0.5 0.625 0.75 0.875) and (0.5 0.625 0.75 0.875 1 0.66 0.33 0)
2: Read a signal vector and delay it: (0 0.125 0.25 0.375 0.5 0.625 0.75 0.875) and (0 0.125 0.25 0.375 0.5 0.625 0.75 0.875)
It seens that PD's [block~] and [switch~] work on second manner (see patch transcribed below).. But my question is this: To work with windowed signals for use with [fft~] and [rfft~] it wouldn't be better to overlap while reading? So I would have more spectral details because the windowing of the two overlaps would "cut" different informations of the signal...
If Puckette read this message, I have a question: On Max/MSP the overlapig of pfft~ object works like that too? It seens to work on the first way... I am asking to you because I imagine that you had implemented it on Max.
Thanks for the answers... J.H.
PS: on the patch I had used a strange way to do the tests but it was useful to me...

block only works in this manner with signals inside the canvas (like the arrays you use). The reading with overlapped signals is done in the inlets/outlets of a patch, so in order to do fft, you have to put the block~ in a subpatch and let the signal enter via an inlet. (The outlet recombines them). You also have to do that because you can not put a dac~ into a patch that has a different blocksize.

But my question is this: To work with windowed signals for use with [fft~] and [rfft~] it wouldn't be better to overlap while reading? So I would have more spectral details because the windowing of the two overlaps would "cut" different informations of the signal...
If Puckette read this message, I have a question: On Max/MSP the overlapig of pfft~ object works like that too? It seens to work on the first way... I am asking to you because I imagine that you had implemented it on Max.
Thanks for the answers... J.H.
PS: on the patch I had used a strange way to do the tests but it was useful to me...

First, let me thank Miller and Geiger for the answers...
So, on my patch I have set the main patch to the same block that the sub-patch with overlaping.... that one is the [pd sub-block]. There is the overlap... So, if the PD worked on the first way, I would have a doubled signal where the samples of the second half of the block would be multiplied by 2 (i.e. second half of the first overlap would be equal to the first half of the second overlap). But what hapens is that the second half of the first overlap is not equal to the first half of the first overlap... If it was a simple sine-wave with frequency equal to (sample rate)/(block-size) I would have a sine wave with doubled amplitude in in the first way (time-continuos overlaping) or a zeroed signal in first case (what happens in PD). On my patch (which need to be initialized with a block choose for all patches - I forgot the loadbang for default 256...) I would have exact a doubled signal if PD worked on-the-flow (of main patch) for overlapping in sub-patch. It ([block~]'s inlet~) seens to buffer the input of the last N samples of the main patch and making a simple delay of N/2, starting there from the beggining of the block. On this way it is the same result of use a [delwrite~] / [delread~] pair with N/2 samples of delay... Isn't it? Sorry if I am redundant or didn't understand your explanations, I am really trying to understand (I have read the chapter nine of Puckette's book yesterday but didn't got it yet. Probably I'll read it with more care on July holidays).. Well, thanks again, Zé

It seens that PD's [block~] and [switch~] work on second manner (see patch transcribed below)..
block only works in this manner with signals inside the canvas (like the arrays you use). The reading with overlapped signals is done in the inlets/outlets of a patch, so in order to do fft, you have to put the block~ in a subpatch and let the signal enter via an inlet. (The outlet recombines them). You also have to do that because you can not put a dac~ into a patch that has a different blocksize.

But my question is this: To work with windowed signals for use with [fft~] and [rfft~] it wouldn't be better to overlap while reading? So I would have more spectral details because the windowing of the two overlaps would "cut" different informations of the signal...
If Puckette read this message, I have a question: On Max/MSP the overlapig of pfft~ object works like that too? It seens to work on the first way... I am asking to you because I imagine that you had implemented it on Max.
Thanks for the answers... J.H.
PS: on the patch I had used a strange way to do the tests but it was useful to me...
