Change microphone gain XP-USB-MIC-UF216
Posted: Thu Jan 23, 2020 10:04 am
Hi everybody,
I'm using a XP-USB-MIC-UF216 board with firmware "sw_usb_audio-[sw]_6.15.2rc1" flashed on this device and working. I just want to use this device as a sound card to capture audio from microphones and process this raw audio signals with my own algorithms.
With this software I'm able to capture audio from the 7 MEMS microphones of this board. However, I'm making some test with a speaker 1 meter away from the "XP-USB-MIC-UF216" board and I check that the audio signals captured have a very low volumen when I listen to them later. I have tried also to capture audio signals (in the same scenario) with Audacity software and the amplitude of the audio signals obtained is the same.
Thus, I would like to ask if you know how to change the microphone gain for this firmware. Could you let me know the paramter I should change if I want to obtain signals with higher volumen. I suppose I have to change any parameter in the code files of this firmware and the reflash my board. am I in the right way??
Thanks in advance.
Antonio
