I had no idea that Trim Silence is a thing, but I can see how that would make audio recordings sound janky. There are times when I'll speed up playback to 2x, but that's usually because the person talking is taking too long to get to the point. Sounds like overkill to me.
I went back to using RSS after I ditched corporate social media in part because I like that the content is just there until I'm ready to read it. I use the Top Day sort on Lemmy and the microblogging platforms are constantly putting new posts in the feed; this is fine for casual scrolling, but I can see how this would be exhausting to people who are trying to keep up with everything. I get the author's need to take a breather every so often. I also find myself wishing that people would chill a bit.
