Hi, you might simply use an online converter such this one https://audio.online-convert.com/convert-to-wav

Or use some other tool suggested here https://www.anymp4.com/audio-converter/convert-pcm-to-wav.html

Or turn PCM into WAV by adding playable header.

Hi @DSull.3 Thanks for sharing the Details. The issue is this convertor supports PCM Details but not Analog Microphone details . I have used the first one it says "Trademark Software" as a Output. All Audio output plays as like this. I think it takes as a ASCII fromat and convert into the WAV file instead the raw data. The other tool uses PCM which is a Digital Microphone Output, but the development board that I have is Analog Microphone.

Hi @Snara.2 , if data come from an ADC then they have already been converted form analog to digital... Typically the microphone has an acoustical overload point (AOP) that defines it's (analogic) full scale, that can be used to tune the ADC dynamics. The X-NUCLEO-AMICAM1 works this way.

STM32 for example embeds ADCs for these conversions.
