fft - Doing audio processing with DFT on a microcontroller ...
https://dsp.stackexchange.com/questions/35107/doing-audio-processing-with-dft-on-a-microcontroller
I have written an audio processing application in C++ which runs on a desktop windows computer. My next step is to implement this on an embedded system using a microcontroller, preferably arm-based. As my application uses fft libraries which does floating point calculations, do I need a microcontroller with a floating point unit, or is there ...
