Works great misses importent core features. I'm still missing a tool that let me adjust the audio by frames, fyi Marques Brownlee did an experiment uploading and downloading the same youtube video 100 times and with every upload the audio will shift 4 frames. And one thing that annoyed me today, was that a video had switched stereo channels, would be great to have a checkbox aside Mono that says switch right and left channel. Then this tool will be a five star add-on for me.

Nice app

works well on music.youtube.com

Brilliant extension exactly what I've been looking for and works very well ; )

Nice. I was looking for one that had gain, but the pan and mono settings are usefull in some cases

A must have app for using YouTube.

I've tried half a dozen volume boost extensions to make quiet youtube videos louder, and this is the only one that worked immediately on installation. (firefox 60.9.0esr on linux)
