Audacity Forum

a working bedroom Love the concept: "What are you doing Steve?" "I'm working.. zzzz" :D If all the pops are louder than your voice ever gets, then the PopMute plugin can detect & silence them all. "PopMute" is a "Nyquist Plug-in". Installation instruction...

what if the result is just silence, but not absolute silence (no negative infinity)? Is it then correct to say that the audio of the two tracks is almost the same, but not the exact same copy? Yes. The sound that is left is the difference between the two tracks. The less the difference, the more th...

There is a common assumption held by many people before they acquire experience recording, that any space can become a recording studio by putting a microphone in it. Experience quickly proves that this assumption is false. To make studio quality recordings, you need a recording space that is extrem...

I think the "correct" answer is to use a better mic - one that doesn't pop when you switch it on / off. Other than that, I think it's a case of editing them out one at a time.

the audio was a 1h20m show I recorder last night That's probably just about big enough for RAM to play a significant role. if it keeps happening, but only occasionally I will log it as what we call a "moonphase bug" If it is "occasionally repeatable", I'd suspect that some part ...

We still don't know if the hum is being picked up acoustically or through electro magnetic interference.

sample no buzzing.mp3 Apart from sub-bass rumble, that is very quiet. I'd say the level of that rumble is low enough to not be a problem. As I wrote previously, that can be greatly reduce with "Low rolloff for speech". sample humming above.mp3 Here's the hum sample after applying "Lo...

I just do not know if the problem is a hardware deficiency

What hardware are you using for playback?

The main hum frequencies are:

60 Hz (strongest)
120 Hz
240 Hz

There's also a rising amount of sub-bass rumble, peaking at around 8 Hz. This can be mostly taken out with "Low rolloff for speech" Eq setting (https://manual.audacityteam.org/man/equalization.html)

As a test, try burying the mic in a big pile of coats / towels / heavy blankets or similar, and check if the hum is more / less or the same.
The idea of this is to see if the interference is sound, or electrical.
