Noise floor suddenly changing

[Trebor]

Somehow my noise floor changes during recording sessions without me doing anything. This is actually a good thing and I’d like to figure out how to replicate it since when I first boot up Audacity it starts at -48, but randomly changes at some point to -54 which eliminates all my background noise. No idea how this is happening though …

Windows could be applying noise-reduction and/or noise-gate, before the sound gets to Audacity.
You should check Windows audio-enhancements are turned off, (in playback & recording tabs).

[ There could also be a second layer of audio enhancements

Audacity as reverb detector

Eureka ! : a second level of audio-enhancements that are on by default … [2nd level audio enhancements.png] [cured- no reverb.png]
