Hi,
Hi all,
I recently purchased an Arducam 8MP IMX219 USB camera (shows as Microdia Webcam Vitade AF, VID 0c45, PID 6366) for use with a NVIDIA Jetson Orin Nano running Ubuntu 22.04.
The camera works great but I’m having trouble with the dual microphones. When I try recording my voice it is extremely soft, not good enough for voice recognition.
What I’ve tried:
-
amixer -c 0 sset Mic 100%— mic is already at 100%, no boost control available -
Recording at various sample rates (8000, 16000, 44100Hz) — same result
-
Software gain reduction — reduces noise but voice is still inaudible
Question: Is there a way to reduce the hardware capture sensitivity on this camera’s microphones? Are there ALSA mixer controls I’m missing? Has anyone successfully used this camera’s microphones for voice recognition with Python on a Jetson?
Thanks in advance!
