I’m getting tired of the extremely loud ads on that don’t seem to be subject to the old TV broadcasting laws that prevent them from being blasted 10db louder than the actual content. Wondering if there’s stuff out there that would let me take the hdmi stream from my Apple TV or other streaming source, and do ad detection like the olden days so that it could just mute or do volume leveling at least.

I suppose something very basic might just be an hdmi splitter to a rpi with hdmi that’ll detect ads via the black screens or “this ad will over over in 30s” overlays, then send a mute signal over CEC or something to a receiver or TV….but would be nice if it could modify the hdmi signal directly.

Thoughts on what to search for to do something like this?

I think you are over complicating things. Just get an HDMI audio extractor (HDCP compliant), feed the audio into an audio compressor/limitor, then you can run the audio into your speakers or buy an HDMI audio injector to feed back into your TV.

why would you want to compress all of your audio. It would make normal content sound terrible

Audio compressors do not compress all of your audio. Please refer to the graph in my original comment.

I'm pretty sure the compression is amplitude compression, just making it quieter not data compression. All the audio information will remain, just volume changed
