Adaptive Volume is a system to keep the level of the input signal near full level, introduced in Media Center 19
There are several use-cases where this feature is useful:
- You use Volume Leveling and don't want the volume of everything turned down a lot unless it's actually necessary to level the volume of the current playlist
- You would prefer to run your DAC close to full level on any input (more important for DSD and classical where the signal may never approach full scale)
- You watch movies at night or in a situation where explosions are too loud and dialog is too quiet
- You're trying to get enough volume out of a low power system, like during playback on laptop speakers.
MC18 added an adaptive volume mode available for video playback. MC19 promotes this system to be available for any media type, and improves it in several important ways.
