So you're recording someone's speech at an important seminar.

There are three microphones. Lavalier, Podium, and on-camera.

The speaker is roaming around the room, and so the lavalier mic is critical .... but .... 16 minutes into the 37 minute speech .... the lavalier breaks down.

You are now an audio n00b with some dodgy audio, sitting in front of Adobe Audition (which you have never used), wondering what to do.

You just want to make the audio bearable.

You try Noise Reduction and then boosting the decibels .... but it still sounds bad. You watch several tutorial videos, but it still sucks.

You then finally give up and go to hydrogen audio begging for help.

The video is here http://www.youtube.com/watch?v=vuv8eQuzrJI (as I say, lavalier goes down at around 16mins .... then quality is variable as the speaker moves around, sometimes closer and sometimes further away, from the remaining microphones)

There's a noise reduction technique sometimes called spectral subtraction that can probably help a bit. Its available in Adobe Audition and probably other audio software too.
