And all of this seems too hard, or too much to learn, right?
It's not. I can't say enough to impress upon you how easy this actually is. If we were talking about music, that's a different story, but we're not. We're talking about podcasts, we're talking about dialogue only. In most cases, the settings for one voice where compression is concerned (for example) will work for almost every voice, you'll just have to turn one knob up or down to adjust for the difference in loudness between speakers. You just need the basics, then you're good.
