1-minute test

[GordynRR]

Audacity, condenser microphone, on a small ARM64 computer running debian. I'm particularly worried that the hardware is not properly grounded and may be generating noise. Therefore amplification, noise reduction, etc have NOT been applied.

Hi GordynRR!
Yes, there is some background noise that we need to reduce. You can see this in the checker tool: https://cgjennings.ca/projects/checker/
As a linux user myself your case is interesting; feel free to tell me more about your ARM64 computer.
Maybe I have old ears but I cannot hear the background noise; admittedly I am not using headphones.

I don't know much about Audacity; I use Reaper which works like a champion on Linux.
I will leave this marked as NOT a pass for now. I could give you a pass; but I think that dealing with the noise and your other issues [?] might be a good thing.
I see that you are already doing sections. Does that mean that you are using this test more as a check up of your hardware?

Hello!

Yes, it's mostly a new-hardware (and new-software-configuration) check. I am using a Raspberry Pi-based device... stuffed into a Gameboy-like case a little over 8in/20cm on the diagonal, marketed as the "uConsole". A really handy and handsome little thing, with new uses popping up every day. In theory, this should be better than a normal computer for recording, because it is totally silent--no fan required!--but on the other hand, it makes all kinds of different electrical noise depending on whether it is plugged in or running on batteries. If you didn't hear anything, that's a great sign; meanwhile, I think I have solved the grounding issue just by running a wire to the nearest drainpipe.

Here is the same recording, amplified 3dB and then noise-reduced 6dB. Strangely, the version of the checker-tool that I installed does not give a noise reading at all... I will look into that, but it's nothing major. Maybe if I try Reaper...

That is an interesting device!
You might want to in Checker go to top list of options and go Validation/Choose Validation methods and then tick background noise check.

Oh! The problem really was just that. Thanks!
