My impression is that the FFT and IFFT in Faust are evaluated for each sample (sliding FFT). I want to do weighted overlap-add (https://ccrma.stanford.edu/~jos/sasp/Weighted_Overlap_Add.html)
I did find a 2013 paper (https://ccrma.stanford.edu/~tsob/site/pdf/frequantizer_report.pdf) that implements OLA using external C++ code. Is there a more elegant way to do it now? Or is Faust not a good fit for this kind of thing?
