Here's another attempt, using a clip from TRM that always bugged me and better sound recorder settings. The one change I made was to increase the output gain to 13db as well.

It's a bit tinny, and you can still hear some music bleed, but in my edits the audio sources vary so greatly that I think it's worth it.
