Enumeration Type Documentation

anonymous enum

Enumerator:

CRITERION_ONSET	Set if the energy just jumped up
CRITERION_END	Set if the energy just fell sharply
CRITERION_MAX_ENERGY	Set if the basic energy criterion is not being met
CRITERION_LO_STABLE	Set if the lower frequency is not stable
CRITERION_LO_OK	Set if the lower frequency is not OK
CRITERION_HI_STABLE	Set if the higher frequency is not stable
CRITERION_HI_OK	Set if the higher frequency is not OK
CRITERION_TWIST	Set if the twist is out of spec
CRITERION_EARLY_CLEAN	Set if the detection is not clean (early in confirmation process)
CRITERION_CLEAN	Set if the detection is not clean
CRITERION_SAME_TONES	Set if the detected tones differ from last time (dual tone only)
CRITERION_EARLY_SINGLE	Set if only a single tone detected (early in confirmation process)
CRITERION_SINGLE	Set if only a single tone detected
