hello,

 i was wondering if there is a plugin that uses the fftw3 library to convert the audio data stream from the time domain to the ferquency domain and vice versa, ( time2freq, freq2time ), so i can use it for analysis ( EQ )
i.e. the pipeline looks like this:
 osssrc ! time2freq ! analysis ! freq2time ! osssink


--------------------------------------

if it doesnt exist, then ...i would try to write one.
but some qtns :
 for the fft plugin, would it be better to convert all data into a float stream, process it, and then covert it back to int ? i.e:
src ! int2float ! fft-t2f ! analysis ! fft-f2t !  
 float2int ! sink
( where fftw3 does the fast fourier transform ).
Or,
 should I keep separate pads for each form of data? 

otherwise
 would the best way be to put it all into 1 big analysis plugin?
 i.e ( src->FFT->EQ->FFT->sink )


thanks,
shanat
