this one had decent audio :D
on the multi audio recording. Premier pro has auto sync (probably other also, didn't use it for a while) and it was pretty good in syncing multiple audio and video sources, it just needs audio in all of them.
on multiple cameras. a lot of clicking and good amount of work for an hour episode.
on RSS feed @brianoflondon is behind Podping and decentralizing podcasting distribution, so i think he could help with how to get on RSS feeds (and spotify). you should look into Podcasting 2.0. Who knows maybe someone throws some sats at you while listening :)
