Hi Team,
I have an GPEVM AM572x with SD card image. The device is boot up from SD image on A15 core.
I want to play the dynamic white noise at Line Out jack. I mentioned the term dynamic because I need to record the real time audio data using MEMs connected to Line-In jack & then need to measure the peak dB level of recorded audio file. Then I need to play the white noise with dB (measured)+3dB level. I had integrated the MEMs to line jack. I can able to record & play the real time data in loop using arecord | aplay linux command. Now please suggest me to play the white noise. If you have any reference libraries or document then please share.
Thanks,
Vaibhav
