Maybe someone could help me.
I'm trying to implement lowpass FFT filter in my vst plugin but i have little problem with my filter output. Output sample chunks seems to be "swapped". But if i comment the most important part of filtering, output is OK. Please look at this image:
I'm using LomontFFT for FFT and IFFT, very simple and efficient library.
my BUFFER_SIZE is 2048, samples contain real and imaginary doubles. Thus i have 1024 samples for signal buffer from host.
Filtering seems to work but data chunks are somehow swapped...
Maybe someone had implement filtering using FFT/IFFT? Could you give me some advice what to do? Or what is wrong with my code, because I'm going crazy trying to make this work for couple of days...
Thanx in advance,
