it's working nicely, however, it blocks "Audio Output Selector" from AgentOink, which is really a pity when you want to listen to music or watch videos on a second device, because you'd have to disable the equalizer to do so.
Maybe there's a workaround or an update that could fix this.

Wow vraiment cool.

With the equalizer, the playback speed does not change.

This the only equalizer that actually works for youtube videos on my Firefox on Gnome/Debian.

Would give 5 stars if I could adjust equalization manually.

I like it just a little lower on bass, since it's trendy to put a lot of basses and I dislike that very much.
Some presets allow me to lower the bass but it's not ideal.
