I need a FFT library for ARM platforms, especially in Apple M1 and Androids. I have already browsed some, but none meets my requirement:
- FFTS has stopped development, and its assembly code do not compile in newer armv8a.
- FFTW is not free for commercial use.
- KissFFT is not optimized, actually it is almost exactly 4-times slower than FFTS.
- CMSIS is rather large and complicated system. I still don't know how to make it work.
- vDSP is Apple-specific.
- I'm trying on ARM ComputeLibrary. But it would be better if there's a smaller library.
I'm using C and C++.
If there's no one, I have to try to write some.
