Hi! I'm trying to use ADC ALC system in DA7212. I switch on high-pass filter by ADC_HPF_EN = 1 (and ADC_VOICE_EN = 1). Unfortunately, input sound of ultra-low frequency - like wind or breath, produces ALC attenuation. Is there any way to filter low frequencies before ALC?
I faced similar kind of issue last time, I am still searching for some proper solution Same issue still no fix to this.
