Hi, I am evaluating MEMS microphone for our application. I am using on board microphone MP34DT01-M in STM32F779NI-EVAL. I am using DFSDM example in STM32F7cube package and able to hear the speech. Now I want to filter the frequencies higher than 1KHz using DFSDM filter configuration. Can anyone help me or give me ideas on this?

Looking forward for your reply,

Thanks and Regards,

Sarath Kumar C
