- Set Audacity to use the External mic.
- Ensure you're recording in 16-bit PCM + 44100Hz.
- Do a sound check, record everyone in the room speaking. You want the lighter part of the meter bar (the green or red bar at the top) to bounce between -12db and -6db while people are talking. It's hard to achieve this... so just settle for as close as you can get, without the bars going off the scale :)
- Play it back and tweak levels until it sounds good @ 60% speaker volume.
- Save the Project BEFORE recording live :D (prevents quality issues)
- Join recordings to one track.
- Listen to it + Edit bad content out.
