I've mentioned Descript a bunch of times, but I'm adding it to Web Excursions because they've added so many amazing features since the last time I linked it that I really think any podcaster/youtuber/screencaster who's not using it should check it out again.
Short description: Edit your audio and video by editing the transcription. Select text, hit delete, media file is cleanly edited automatically. Descript now has a full suite of audio plugins (limiter, compressor, hi/lo cut, multiple eqs) as well as some wizardry to boost and level audio without a single dial to fiddle. If you're spending an hour or more every week editing a show, you really need to see this.
