	size of table is DFT size divided by 2. So if analysis with N=1024, use at table size of 512. see https://csound.com/docs/manual/GEN43.html size -- number of points in the table, power-of-two or power-of-two plus 1. GEN 43 does not make any distinction between these two sizes, but it requires the table to be at least the fftsize/2. So in my case: The output is: analysing 35280 sample frames (0.8 secs) from timepoint 1.0 frameSize=1024 the FrameSize = 1024 so it takes only one Frame to fill the 35280 analysed samples. It doesn't matter if i analyze .5 seconds or 3 seconds- only 1 Framesize is created, right? In my case, only 1 photo of 1024 size is taken...and table size for GEN43 is thus 512 or 513...

	yes, GEN43 reads the whole file and produces 1 DFT frame. ======================== Prof. Victor Lazzarini Maynooth University Ireland > On 17 May 2021, at 10:33, tjingboem wrote: > > WARNINGThis email originated from outside of Maynooth University's Mail System.
