![]() ![]() ![]() What’s more, those super-sensitive mics could pick up my voice from all the way across the apartment during testing, some callers said they could hear me clearly (albeit at a very low volume) from roughly 30 feet away. Logitech says the mics should capture crystal-clear audio from up to a meter away, but in my testing, I had to move roughly six feet from the mic before callers noticed any drop in clarity or volume. Whereas my Zoom room buddies said it sounded like I was in an echo-filled tunnel of some kind when using my laptop’s mic, the C930’s omnidirectional mics made a tremendous, immediate difference in sound quality. ![]() The Logitech C930e’s mic quality is, in a word, out-friggin-standing. Logitech C930e webcam review: Mic quality Video and audio results were similar in quality no matter what program or app I used the field of view was vastly expanded with the Logitech C930e, and images far more true-to-life. (The function is part of SkinnerTrax, a real-time tracker for Drosophila I wrote.) There is also pyuvc, which seems relatively cross-platform but I have not tried it.Indeed, when I switched over to the LG Gram’s webcam, it looked like I was using a grayscale filter in comparison, and there was an immediate drop in audio/video quality across the board. The utility function I wrote for getting and setting V4L2 controls is on GitHub and has a bunch of additional functionality such as handling of default values, multiple controls, and multiple batches of controls, which makes the code more intricate than a simple "change zoom level" example would be. To do this from Python, I used subprocess.check_output(). You can change the controls, e.g., with v4l2-ctl -d 0 -c zoom_absolute=10. Zoom_absolute (int) : min=0 max=10 step=1 default=0 value=0 įocus_absolute (int) : min=0 max=40 step=1 default=0 value=8 Here part of the output of v4l2-ctl -d 0 -l for a Microsoft LifeCam Cinema. To figure out what controls the camera provides via UVC, on Ubuntu you can use v4l2-ctl, which is in package v4l-utils. ![]() According to its specs, the C930e is UVC-compatible (as most webcams are), and it most likely allows zoom level control via UVC. ![]()
