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 MCU Lütfer

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