Try amplifying the audio a bit first, then run this code in the "Nyquist Prompt" effect first: Then use Noise Removal with something like:
Noise Reduction: 8
Sensitivity: 12

1) I don't like the idea of intermediate file conversions, because it seems like there will be information lost in the process. (What intermediate format would you recommend on a PC? 32 bit signed WAV?) Ideally, 32-bit float. This is the format that Audacity uses by default internally, so there is ...

saving the project BEFORE recording for some reason seemed to help the "stalling and stopping recording in the middle of recording" problem, The difference that makes is that the audio data will be written to the _data folder where you saved the project rather than to Audacity's temporary...
