These are very similar things to the features the MaxxAudio control panel offered (and now that I think of it, my ancient Windows 8 tablet had Dolby-badged software on it with a similar feature set): - Custom response curves for the built-in speaker as well as some brand speakers/headphones (responsible for the "what did you just plug in?" dialog that annoys many users) - User-adjustable EQ - Compression, limiter, AVL, "night mode", loudness: I'm lumping these together in one basket as I don't know what components were in use behind the scenes - Reverb: for cases where you want to listen to music that comes out of a PVC drain pipe of a concert hall's restroom - Possibly downmixing multi-channel audio for headphone users, but I'm not sure in this one either.
