DTS 2.0 + Digital Out »

Dynamic range

This refers to the difference between the

The dynamic range is measured in units

is compressed (Audio DRC), the minimum

signal level decreased. This way, the
volume of loud sounds such as explosions is
reduced, while the sounds with a low level,
such as human voices, are easier to listen
to.
