Hi,
currently GstFFT somehow scales the data given to kiss the wrong way (i.e. not
at all). To make it possible to call a fft and on the same data an inverse fft
and get the same data again some scaling is necessary, I have that fixed for
the floating point data types locally but I'm still fighting with the fixed
point implementations.
The missing scaling also resulted in wrong magnitude being calculated.
Bye
