Define Documentation

#define DYNRNG_LONGTEXT

Value:

N_( \
    "Dynamic range compression makes the loud sounds softer, and the soft " \
    "sounds louder, so you can more easily listen to the stream in a noisy " \
    "environment without disturbing anyone. If you disable the dynamic range "\
    "compression the playback will be more adapted to a movie theater or a " \
    "listening room.")

#define DYNRNG_TEXT   N_("A/52 dynamic range compression")

#define LIBA52_FIXED

#define UPMIX_LONGTEXT

Value:

N_( \
    "Enable the internal upmixing algorithm (not recommended).")
