C# Class GAudio.GATRealTimeADSR

Wrapper that adds realtime ADSR controls to IGATDataOwner objects( GATData or IGATProcessedSample ). In addition, zero crossings are automatically found for the sustain loop, and a sustain loop crossfade can be adjusted.

Public Methods

Method Description
GATRealTimeADSR ( IGATDataOwner dataOwner ) : System.Collections

Wrap a GATData or a IGATProcessedSample object for ADSR playback.
PlayThroughTrack ( GATPlayer player, int trackNb, float gain = 1f ) : void

Starts playback through the user specified player.
PlayThroughTrack ( int trackNb, float gain = 1f ) : void

Starts playback through the default player.
Release ( ) : void

If playback is in the loop crossfade part of the envelope, the sample will loop one last time and release from the sustain index.
TrySetEnvelope ( int offset, int attack, int decay, int sustain, int release, int loopCrossfade = -1 ) : bool

Call TrySetEnvelope before playing. Processing of the sample occurs in real time, but the envelope parameters cannot be modified while the sample is playing. Note 1: a sustain of 0 is valid and will result in one shot playback. Note 2: if no loopCrossfade parameter is passed, loopCrossfade will equal sustain. Note 3: offset + attack + decay must be greater than loopCrossfade.
