Describe the change or feature you'd like to see added to HandBrake:

A clear and concise description of what you want to happen.
Although HandBrake can compress AC3 codec audio, it would be better if there were an option to additionally limit the audio as well; for those who are not conversant of the difference, an audio limiter limits the maximum level an audio signal can reach, whereas an audio compressor will both limit maximum audio level and also boost low level audio (set by the compression ratio).

Why would this be useful? Because on high-dynamic range audio, if you attempt to set a high audio compression ratio in HandBrake, you get a issue called 'pumping', where low level audio gets lifted up & down, sounding very poor. The addition of a limiter would mean you could set a lower compression ratio, then add some audio limiting as well.

What version of HandBrake are you currently using? (e.g., 1.0.0)

All including current.

What operating system and version are you running? (e.g., Ubuntu 16.04 LTS, macOS 10.3 High Sierra, Windows 10 Creators Update)

Mac OS X 10.12.6
