Dear Eric and Team,

after spending hours on researching and studying OpenSL ES I still couldn't find out which DSP technique it uses for the equalizer, or in general.
Is it Fast Fourier Transmission (FFT), Digital Filtering or something completely different?

I would really need this information for a paper I'm currently working on, so any help, hint or response are very appreciated.


Thank you very much,
Best,
Reinhard
