it actually WORKS!!! I had a compressor built-in to an "Improve YouTube" extension on Opera, but it wasn't made for Firefox.. and I couldn't fins ANY that would work on YT, let alone ALL the audio... but then I found this and it works GREAT! And I don't have to refresh any tabs or restart the browser either, it worked right away - THANK YOU DEV TEAM!!!

Works great with Firefox, but not Chrome or Edge. But Firefox has other deficiencies. I wish I could find one browser that does everything, but at present I have to run atleast two simultaneously.

Very useful for watching horror game streams lol

Works really good. Looks like it has regular updates as well.

the icon doesn't always update to show the correct on/off status. also wish the enable toggle is bigger.

outstanding for youtube

Amazing tool, works perfectly, compatible with most websites, and remembers settings for each website which is an amazing feature.

If like me you struggled to hear properly the vocals while watching Netflix, then this is your miracle add-on extension.

An absolute must for any Firefox user!

This Audio compression extension add-on works amazingly well on a DELL XPS 13 Late 2018 (9370) with the default audio drivers installed.

I could not believe how good these made the built-in stereo speakers sound.

Phenomenal work on the DEV's side!

Get it while you can and mess around with the parameters until you get the desired outcome.

Works, but prevents my computer from sleeping on Windows 11 with a paused video open

Perfect, when listening to movies online this app lowers the volume of spikes, that is, weapon, loud music, explosions, etc., while keeping the dialogues at the same level. And also it has a functionality to boost sound, which makes it even better for audios with very loud sound.

Enabling this extension completely disables sound in some websites (like factorio.com). The sound only works when I open the video in a new tab. I have tried the 'none' preset too, but the sound only works when I disable the extension (either using the checkbox or using firefox). EDIT: Github issues shows that this is a Firefox problem, not an extension one. This problem can easily be fixed by disabling it for troublesome sites.

Sounds like it's doubling the audio.

Works as intended

The button doesn't even show-up on my toolbar and I don't see it listed when I choose customize. How do I get it to appear?

Nice audio enhancement for Firefox!

Thanks! Very usefull for online video and movie. I'm so tired of endless sound volume adjusting, so this thing is must have for me

(updated review)

It's great. It's very adjustable and the sound is pretty transparent. It activates automatically and reliably, unlike many other sound boosting addons (that either don't self activate reliably or have to be manually activated every time). It also doesn't mess up Youtube's playback speed options, they work correctly, also unlike other volume boosting addons. It doesn't work on every site under the sun, but works for many major streaming and music sites.

The only problem is that there are some audio stutters (especially on Youtube). They don't happen often, but kinda annoying. In it's defense, this is a problem that other volume boosting addons also have, so maybe there's just no way to have it working perfectly.

99% sites I've ever used work with it. Set it to medium and forget it, all YouTube videos improved now that I'm not constantly turning volume up, down and up and down over and over again. Thanks!
