It's just a low pass filter. Since human speech is massively out of the frequency range of a fan, you can just delete that whole frequency wholesale.

Audacity (or Audition/Cool Edit how the old guys know it) is a bit smarter. It can analyze a recording of the noise floor and then just attenuate that. It's bad for quality music but good enough to improve speech, old tape recordings and records.

This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.
