Please find the attached audio and asound.astate

There is so much background noise , is it possible to refined it using HFP setting

Please help

Hi Nitin,

It sounds and looks like the input volume is low. You can change this by adjusting the PGA gain or the volume.

As you can see in the system diagram, the PGA is the amplifier that the inputs reach first, which can vary from 0dB to 47.5dB of gain. It looks like your setting "PGA Level Volume" is set to 0 so there is no gain on the input. You can also set the digital volume of the ADC with the "ADC Level Volume" control in your astate, this can be set from -12dB to +20dB of digital volume. I would recommend setting the PGA level to a reasonable value that would correspond with your input voltage level of your microphone and then fine tuning the volume with the ADC Level Volume, the digital ADC volume. I see you have your ADC Level Volume up at 57, which is near the max it looks like, so see if you can increase the PGA volume if this will help.

Best,
Mir

Hi Mir

This is about the background Noise .

Please find the updated asound state and audio , there is so much background noise

Please listen this sound to audacity and you can see the wind noise present there

Hi Nitin,

What changes did you make here? It sounds louder but yes I hear the background noise. It may also be due to your microphone, it may have a physically wide range where the audio is picking up so it picks up a lot of background noise, or is not close enough to the subject. Background noise is not necessarily fixable with the codec, it would be more with the microphone arrangement. You may also want to increase the input impedance from 10 kOhm to 20 or 40 kOhm to see if that helps... that is the only thing hardware-wise that I can think of that you can change on the codec itself.

Best,
Mir
