Hello Experts Could anyone suggest me how to convert the raw PCM values received in log file be to mp3 or .wav formats .And if there any libraries that could be included or any method? after conversion storing that into sdmmc and play that as loopback?

Associate II

The Acquired PDM signal is from VM3000 mic and PDM2PCM conversion using stm32f745?

could the acquired values be played as loopback to verify whether the acquired sound is in audible frequency to human ears?

How could this be validated? all suggestions are welcomed. Thank you in advance
