Bug Description

Binary package hint: pulseaudio

Audio dynamic range compression allows for dialogue to be loud enough to hear while explosions are quiet enough to not wake the neighbors.

In July of 2008 it was an "upcoming feature": http://0pointer.de/blog/projects/jeffrey-stedfast.html

Detailed explanation: http://en.wikipedia.org/wiki/Dynamic_range_compression

On that other OS I can achieve this perfectly with ac3filter, by following this excellent guide:

Oh how I wish the same would be possible on Ubuntu.

I am surprised that it this feature request does not seem to be a popular one.

I find it quite frustrating that there is no userdefined maximum to the volume output.

Now when I play a soft video/audio file I pump up the volume. That's quite ok. But after that I forget that the volume is set to a high value. When I start the next file my eardrums are nearly torn apart and I do not like that at all.

So, I am not looking for a very sophisitcated DRC. I just want to set a maximum to the audio output systemwide.

Are there any known ways how to realize this in Ubuntu?

I'm sure there must be tons of people who would want this, they just don't know about it... I just thought the sound in Ubuntu is flat, and the only thing I miss from Windows is Breakaway Audio Enhancer. Then I found something called audio compression in VLC, which seemed to be what I missed.. But like all else here, I would like this to work system-wide!

I would be surprised if PulseAudio still lacked this feature. Are you sure it's not covered by one of equalizer modules?

If not then someone please request the feature from upstream here:

  https://gitlab.freedesktop.org/groups/pulseaudio/-/issues

and then tell us here the ID of that feature request.
