EDIT: it looks like this was probably a problem on my end, likely from using more than one audio extension at once (and a resultant duplicated audio stream). I've since removed my EQ extension and this works really well. thank you!

OUTDATED:

4 stars for absolutely doing what it says on the tin. unfortunately, it makes the audio sound very bad right now. a previous review described it well, but it sounds like it could be a weird double-audio phase problem, or a slight reverb or delay. not sure, but the fact that this exists is an accomplishment in itself, so thank you!

Отлично, теперь можно смотреть фильмы нормально, не боясь что после максимально тихого бубнежа из-за которого приходится добавлять громкость последует перестрелка от которой уши вянут, поставил на high и громкость отлично выровнялась

Before that, it was a great plugin ever, but now it sound like have a reverb behind. Don't know what happen.

does what it says. thanks.

Cumple lo que promete, los sonidos bajos se amplifican y los sonidos altos no son alterados para que todo el sonido sea uniforme. El slider de boost amplifica todo el audio después de pasar por la compresión

Got sick of listening to spoken content on YouTube with wildly varying levels between videos. This thing is hell on wheels.

I started with 'Medium' and settled on:

-30,30,10,0.001,0.275,0

I noticed it seemed to introduce some peaking while enabled, but dropping the volume on the YouTube player to ~95% took care of it.

I don't use it for e.g. music playback, so I can't speak to that.

Thx vatara, realy happy about :D

It works, but the sound quality is poor.

whoop! Was gonna write the code myself to do this as a custom script in the youtube enhancer extension but now I don't have to :)

** EDIT: **
Thanks for the quick reply. Very much appreciated.

Now, though, I'm having persistent audio issues with the compressor:
— an out-of-phase doubling of the sound
— minor distortion
.
Unsuccessful troubleshooting attempts I've tried already include:
— extreme and mid settings
— disabling my "Audio Equalizer" plug-in
— switching to and from Bluetooth headphones
.
Any ideas?

Question for vatara, "Audio Compressor" extension dev:
.
I try to avoid any browser extensions that aren't vetted ("Recommended by Mozilla"), so I'm wondering which aspect(s) of this extension require such highly-sensitive user-data to function?
.
The extension needs to "access your data for all websites", which means that anything I type on any website, including:
— usernames & passwords
— work emails
— my highly-personal . . . "dear diary...today after 4th period, Jason actually looked at me!!!!11" . . . kinds of Google-Docs-diary entries
— tragic and sad Reddit comments of mine on r/Gonewild50Plus
.
Apart from this question holding me back, everything about the extension itself looks good enough to try.
What do you say?

Does what it says. The UI could be cleaned up a bit and a shortcut to enable/disable would be really good to have.

Exactly what I needed!! And for such a long time... it's perfect for what I need it for. Thank you for making this. Begone crappy unleveled audio!

What it needs: Non-URL based profiles. Because using URLs are confusing.

Review: Lovely add-on. Works very well. You will have to have a basic understanding of what a compressor does before you can play around with the settings.

For those who wants to boost and compress audio, just select anything from Low, Medium to High, and play around with the "Boost" slider for a quick fix when listening to audio that's very low in volume.

Doesn't really work. If the volume is turned up, the volume won't be compressed. This sometimes happens when videos on websites are set to MAX volume. Hope you can fix this problem because i really need a nice compressor

I agree it would be much better if we could limit the effect to only one tab, while disabling it on other tabs.

EDIT:
Ah yeah. It's was just a bit odd, saving on one page, then having to go to a different tab to turn it off for all the other tabs. I think that was because the default was set to on though, I've made the default off, so hopefully it will stay off now, unless I save.
