Hi,
I have configured the codec (tlv320adc3101) from linux user space.
I am able to capture the Audio using MIC input.
But some noises are recorded along with sound data. I have tried the capture with various sample rate frequencies like 8000, 16000, 48000, 96000 Hz.
8000 Hz sample rate frequency has more noise, 16000 Hz has less noise compared to 8000 Hz, where 48000 and 96000 Hz contains very less noise compared to lower frequency rates.
When sample rate increases, we are getting less noise.
I have attached the recorded wav files below for your reference.
1. 16000 Hz wav file
2. 48000 Hz wav file
3. 96000 Hz wav file
If you want i can share the codec configuration details.
Do you have any idea about this issue?
Regards,
Rajesh
