How do I get the best sound quality for recording a webcast?
If you’re recording your own voice, pull the sound from the microphone. If you’ll also be recording the participants, you’ll need to do a bit of post-processing to get their voice to the same level as yours, remove background noise, etc.
If your webcast host offers it, let them do the recording and get the raw audio for editing. They’ll generally do this for little or no money.
Also, test it out your system ahead of time before the “big day”. It’ll let you tweak the various parameters to find something that works.
