I've been using Easy Effects for a long time. I almost exclusively use the "Noise Reduction" filter which is based on Xiph RNNoise. It is absolutely fantastic at removing my keyboard and other background noise from my microphone. And the UI is so easy that it is trivial to click it off if I want to record something raw and do the processing later. There are also compressors which can be useful and pitch changers which can be fun. I have it set to start up automatically and I forget that it is even running. I've donated in the past but I think I'm due for another round. The developer is super friendly and helpful in the issue tracker (although I haven't been there for probably a year now as it has been rock-solid recently after the PulseAudio to PipeWire transition bugs have been hammered out)
