NoiseTorch - Noise reduction
Really easy to setup, and has GREAT results!
Allows filtering the input (microphone) and output (headset).
Low resource consumption
~2.5% CPU on a i5 (meaning, ~2.5% of one core)
~17Mb of RAM
(As of [ 2021-03-27 Sáb ] ) will introduce ~10ms latency on input (if filtered) and ~100ms on output (also, if filtered)
