Hi,
I am trying to implement a speech IO system using stm32f4 discovery board. For this I am using interrupt for extracting(from digital mic) pcm samples to a buffer & for output(using polling) I am continously writing circularly the same buffer content to the codec.
In this case I am getting noise at the output & some signal content. So shall I use ping pong buffer for smooth playback or a single buffer is sufficient?
Can you please explain?
Thanks & Regards
