Is there any program that can equalise/normalise audio output to a preset level real time?

I dont want to disturb my neighbors at nights when I am watching youtube videos sometimes they are a series of clips which have different volume

so one clip is loud at e.g 10% and the next is barely audible at 30% volume bar then the one that follows could be earbraking at 30% volume bar etc

volume bar = youtube player volume bar.

So is there any program that can automatically lower the volume if it exceeds a preset limit in real time?

I am not talking about controlling the youtube volume bar per se (I suppose that would be harder) but a program that monitors the audio volume that gets outputed from the audio chip's green minijack out and balanace it to a certain volume.

  • Not sure about Ubuntu here but that's typically something you could fix with some kind of audio compression. – mchid Apr 24 '17 at 7:54
  • What do you mean? – papajo May 7 '17 at 7:36
  • en.wikipedia.org/wiki/Dynamic_range_compression Sometimes it helps to throw around these terms when looking for something. It's usually just referred to as "audio compression" or a "compressor" to limit the volume in decibels. – mchid May 7 '17 at 7:39
  • I guess this could also be described as a limiter. – mchid May 7 '17 at 7:45
  • You would want extremely steep or fast minimal attack and decay. There is a complicated similar post here which may help you as sort of a work around, although, I do understand that you are looking for an easier solution: askubuntu.com/questions/95716/… – mchid May 7 '17 at 7:55
