Ahoy, guys!
DRC is back! It is present on YouTube for Android as "Stable volume" and it is optional.
I am curious whether or not this is present on PC browsers and whether it is optional there as well.
EDIT 2: It seems like DRC is not present at all on music, as far as I can tell (for now):
EDIT 3: I don't see any option on PC to enable it. YouTube links also does not identify more than 2 audio streams (AAC and Opus).
this script isn't working for me, any advice on how to fix this?
thanks
Is there a script out there that removes DRC? This script is no longer effective for removing normalization, at least for me since everything is DRC normalized.

@AshleighTheCutie Check out Nova Youtube. https://github.com/raingart/Nova-YouTube-extension
It includes the function of this script and many many more things, similar to Iridium.
