Actually the main function of DPS is dynamic range control. This means DPS is is like a volume limiter on steroids. The trick is selecting the profile that has the amount of volume limiting you like. That is also why we include the Movies mode. The Movies listening mode actually ramps up the amount of volume limiting to account for the wider dynamic range of movies with consideration for the playback device.
When it is night time and I’m playing a video game or watching video, I usually switch to the Philadelphia Speakers profile. I designed this profile to have maximum clarity for voice and music at very quiet volume levels. This means it functions very well as a volume limiter as you describe. Give it a try for this purpose ant let us know what you think!
MODERATION: I’ll keep this as the main thread and delete the second post on this subject to avoid confusion.
