Using rnnoise you can record your microphone with ffmpeg with noise suppression to cut out background noise like noisy fans

rnnoise is the same tool used by obs studio

In this video i take my obs microphone settings and convert them to ffmpeg filters using rnnoise, a noise gate, compressor, gain and limiter

This lets you use ffmpeg with the same settings as obs studio for recording your microphone

I also cover using rnnoise with emacs, whisper-cpp and whisper.el to transcribe audio with your microphone in noisy environments
