ipatch_unit_dls_class_convert ()

int
ipatch_unit_dls_class_convert (guint16 src_units,
                               const GValue *src_val);

Converts a value to "DLS" units. DLS units are unit types that are used by DLS (Downloadable Sounds) patches. The IPATCH_UNIT_CLASS_DLS map is used to lookup the corresponding type to convert to. Only some types have an associated DLS type. It is an error to pass a src_units type that has no DLS mapping (note that this is contrary to the behavior of ipatch_unit_user_class_convert()).

ipatch_unit_dls_percent_to_percent ()

double
ipatch_unit_dls_percent_to_percent (int dls_percent);

Convert value in DLS percent units to percent.

percent = dls_percent / (10 * 65536)

ipatch_unit_percent_to_dls_percent ()

int
ipatch_unit_percent_to_dls_percent (double percent);

Convert percent to DLS percent.

dls_percent = percent * 10 * 65536

ipatch_unit_dls_gain_to_decibels ()

double
ipatch_unit_dls_gain_to_decibels (int dls_gain);

Converts a value from DLS gain to decibels.

dls_gain = 200 * 65536 * log10 (V / v) decibels = 20 * log10 (V / v)

ipatch_unit_decibels_to_dls_gain ()

int
ipatch_unit_decibels_to_dls_gain (double db);

Converts a value from decibels to DLS gain. See ipatch_unit_dls_gain_to_decibel()

ipatch_unit_dls_abs_time_to_seconds ()

double
ipatch_unit_dls_abs_time_to_seconds (int dls_abs_time);

Converts a value from DLS absolute time to seconds. seconds = 2^(dls_abs_time / (1200 * 65536))

0x80000000 is used as a 0 value.

ipatch_unit_seconds_to_dls_abs_time ()

int
ipatch_unit_seconds_to_dls_abs_time (double seconds);

Converts a value from seconds to DLS absolute time. dls_rel_time = 1200 * log2 (seconds) * 65536

ipatch_unit_dls_rel_time_to_time_cents ()

double
ipatch_unit_dls_rel_time_to_time_cents
                               (int dls_rel_time);

Converts a value from DLS relative time to time cents. time_cents = dls_rel_time / 65536

ipatch_unit_time_cents_to_dls_rel_time ()

int
ipatch_unit_time_cents_to_dls_rel_time
                               (double time_cents);

Converts a value from time_cents to DLS relative time. dls_rel_time = time_cents * 65536

ipatch_unit_dls_abs_pitch_to_hertz ()

double
ipatch_unit_dls_abs_pitch_to_hertz (int dls_abs_pitch);

Converts a value from DLS absolute pitch to hertz. hertz = 440 * 2^((dls_abs_pitch / 65536 - 6900) / 1200)

ipatch_unit_hertz_to_dls_abs_pitch ()

int
ipatch_unit_hertz_to_dls_abs_pitch (double hertz);

Converts a value from hertz to DLS absolute pitch. dls_abs_pitch = (1200 * log2(hertz/440) + 6900) * 65536

ipatch_unit_dls_rel_pitch_to_cents ()

double
ipatch_unit_dls_rel_pitch_to_cents (int dls_rel_pitch);

Converts a value from DLS relative pitch to cents. cents = dls_rel_pitch / 65536

ipatch_unit_cents_to_dls_rel_pitch ()

int
ipatch_unit_cents_to_dls_rel_pitch (double cents);

Converts a value from cents to DLS relative pitch. dls_rel_pitch = cents * 65536
