Hello guys,

I am doing some audio project with tennsy 3.2 + audio board. Now i've calibrated microphone on audio board and adjuted to show the decibels. I think that works quite fine.
I also found option "adcHighPassFilterEnable();". If I understand correctly, this function is used by default, even if I don't use it and it cut the low frequency noises?

Does it works like A-weighting? Can I somehow set the border frequency of filtering (in case if cuts "too much").

""By default, the analog input (either line-level inputs or mic) is high-pass filtered, to remove any DC component.""

Every answer will be helpfull.

Best regards,
