Acquiring audio signal using ADC

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

Look in the STM32F1xx DSP Library Firmware available in the STM resources section for STM32 processors.

Cheers, Hal
