Removing a steady hum from a recorded talk

Recording a talk or a screencast often picks up a steady noise: a fan, HVAC, or a laptop coil. If that noise stays constant, you can strip it without opening a full audio editor.

I have been using EraseNoise for that case. It removes steady background noise from speech in audio and video. There is a free preview; Pro is about $9.99 a month.

It is not a fix for a noisy cafe or two people talking at once. It is the simple case: one speaker and a steady noise floor.
