i have developed a nn for audio on python so my pre processing code is in python language and i have used different kinds of libraries such as librosa and i wanted to know if i could implement those (my preprocessing) into my MPU(STM32F411VETx)

[AMohs.1]

if not could you introduce some MPUs that i can substitute?

Thanx:folded_hands:

There is no magic tool that will transform all your existing code into a highy efficient MPU firmware, regardless of the MPU you are choosing. Familiarize yourself with the STM32 AI ecosystem: https://www.st.com/content/st_com/en/ecosystems/stm32-ann.html. For audio processing and general signal processing, there are also dedicated libraries like https://www.st.com/en/embedded-software/stm32-audio100a.html and https://www.st.com/en/embedded-software/x-cube-dspdemo.html.
