RNNoise 8bit fixed-point implementation and realtime noise suppression on MCU

[majianjia]

Hi,

Thanks for RNNoise providing the great low-cost method for noise suppression.

To who may interest, I have implemented a similar RNNoise using fixed-point interference NN lib NNoM. In my test, an STM32L467 is capable of running the noise suppression in realtime, taking only 6k RAM and 38% of the CPU load.

For more info and source code please check the Example and Audio demo.

Thanks Jianjia
