I'm using ADSP-21375 and I'm trying to make some manipulations on audio data, but I have some problems.
I want to apply fft on the first input, make some maths and then apply ifft to back in time domain. At last, I want to make a convolution with the second input. I'm not interested in real-time.
Problem using filter.h:
- I can't use convolve function with complex_float type.
- Can I write out_complex.re and out_complex.im to get the real and imaginary part of the output of the rfftN?
Problem using trans.h:
- This header does not contain a convolve function.
- Moreover, I read that rfftN and ifftN functions take the input data reversing the bit. Does it mean I have to flip the input and/or the output? This point makes me confused.
Thank you very much for your help!
