This is interesting to know, do you have a full demonstration ? and did you tried to use ST official one and compare it to your implementation ? If yes, please let us know to share it to forum users.
I'm trying to achieve 4kb/s with speex using STM32. The sources provided by STM are supporting only 8kb/s, and this works me. 4kb/s don't work, I found in STM sources that this mode isn't supported, or I'm doing something wrong?
I need to add, that I'm using gcc compiler. Vk how did You run with 4kb/s ?
I need to take original speex version from speex.org, and only compile to this processor?
