I'm using Audacity 1.2.6 with Win XP to capture meeting discussions. These are discussion via the Internet and occasionally VoIP through my sound card. The actual (live) voice sounds reasonably good, but the Audacity recording (*.mpg, or *.mwv) sounds hollow with some noise. I'm looking for advice as how to improve the quality of the recording. What setting can be adjusted to improve the sound quality.
