Define Documentation

#define BUFF_LONGTEXT

Value:

N_("This is the number of audio buffers on which the " \
                "power measurement is made. A higher number of buffers will " \
                "increase the response time of the filter to a spike " \
                "but will make it less sensitive to short variations." )

#define BUFF_TEXT   N_("Number of audio buffers" )

#define LEVEL_LONGTEXT

Value:

N_("If the average power over the last N buffers " \
               "is higher than this value, the volume will be normalized. " \
               "This value is a positive floating point number. A value " \
               "between 0.5 and 10 seems sensible." )
