Waveform display
Controls how much of a sound’s waveform (amplitude representation) is displayed in the Time Slider. Default is Top.
Specifies how much sound (in the current time unit) is repeated when you turn on Repeat on Hold. 1 specifies the smallest segment of sound—about one-third of a time unit in duration, with the other two-thirds being silent. 2 specifies about half a time unit of sound, the rest being silence. 3 species that the sound loops for that time unit. Only available if Repeat on Hold is on.
