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!

(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!

I use this plugin mostly on Youtube for gamestreams as i got used to FFZ on Twitch which has a build in compressor, this works great. Today i tried it for the first time on Kick.com, seemed to have a few muting issues but i got it working now and works similarly nice. I like the site specific presets a lot, well done.

works okay when it works, but now it mutes audio on several sites unless i deactivate the extension entirely. might try again in the future but it's broken at the moment.

One of the best extensions out there right now

It's perfect for badly made and unbalanced videos on the internet (one speaker is louder than another in debates, volume drops/spikes etc). Also, I don't have Netflix but I know they usually buy films with mixes for cinema (its cheaper than paying for a new mix) which has huge dynamic range so this can maybe help you reduce it and save you many volume slider adjustments. Thank you very much.

Thank you so much for this. I got new speakers and couldn't use the loudness equalization setting for windows on them and was extremely bummed out. This solved that problem for me, huge life saver thanks a ton.
