This is just what I needed. Higher pitched tones really disturb me. Thank you very much \(0.0)/

Guter Klang und leichte Einstellungen

Just about perfect

l'extention équalizer est super pratique, on peut tout gérer le top!

It's not a bad little audio tool. I like the pre-sets.

I use this to fine-tune music on YouTube (bass specifically). It does that job perfectly, hence the score. However this Add-on breaks a lot of other video related services like twitch.tv and certain file/flash types (.webm) for me. You will have to turn it off manually in the Add-on menu and hard refresh the page to get everything working properly again. @Dev: A quick on/off button when clicking the icon would be great for this reason. Happy holidays.

I like my "Audio Equalizer" by Muyoo a lot because I can boost the bass inside my "Firefox" application!

Excellent tool, preset saving possibility is very usefull !

Спасибо! Вы спасли мои вкладки с музыкой в любимой firefox :)

No fast On\Off access.

As user friendly as the addon seems, it ran slow and made the audio sound distorted (in my case at least). I wouldn't use this for bass boosting any audio or music.

Excellent, it works great!
