Dear David, The reason I was using https://github.com/piratfm/codec2_m4f instead of https://github.com/drowe67/codec2 was to have a clean and minimal code for the core of Codec2 on Cortex M4. Actually, first I tried to port from https://github.com/drowe67/codec2 but it turned out there are some many codes related to peripherals there. Is there any minimal library of Codec2 for ARM?
