>> If there's a 3-band EQ built in, it should probably be an 8-band instead.

My thoughts exactly. When I used OBS there was no equalizer. Later I decided to try making one and found they had a new 3-band which was useful for learning how to make audio tools and I was happy to bring my 8-band idea to life. I submitted a PR and one of the devs shepherded me through a few cleanups to make it acceptable. Then they rejected it as somehow non wanted in the project. As an OSS maintainer myself I get it - even though I don't understand the reasons they seemed divided on it since one of them helped with the PR. I try not to speculate on the why, so I have just kept my fork there with the 1 commit to add the 8-band. It's probably way out of date so I should rebase it on latest release. Sounds like there might be some naming convention changes too but I need to find time to look into it.
