Hi all,

I am a newbiew with audio projects and I need your skills...
I am acquiring the analog signal using the ADC of the STM32 and now I need a digital filter to filter out the noise. Once done I will output the samples on DAC.
Do you have some interesting tools (for audio) that make my projects easy?
Is there a ready to use digital filter running on cortex M3 or cortex M4?
Thank you for your proposals...
PS: I am using STM32F103
