unreal.OnsetNRT

class unreal.OnsetNRT(outer=None, name='None')

Bases: unreal.AudioSynesthesiaNRT

UOnsetNRT

UOnsetNRT calculates the temporal evolution of constant q transform for a given sound. Onset is available for individual channels or the overall sound asset.

C++ Source:

  • Plugin: AudioSynesthesia

  • Module: AudioSynesthesia

  • File: OnsetNRT.h

Editor Properties: (see get_editor_property/set_editor_property)

  • duration_in_seconds (float): [Read-Write] The duration of the analyzed audio in seconds.

  • settings (OnsetNRTSettings): [Read-Write] The settings for the audio analyzer.

  • sound (SoundWave): [Read-Write] The USoundWave which is analyzed.
