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.

Method Details

GATRealTimeADSR() public method

Wrap a GATData or a IGATProcessedSample object for ADSR playback.

public GATRealTimeADSR ( IGATDataOwner dataOwner ) : System.Collections
dataOwner	IGATDataOwner
return	System.Collections

PlayThroughTrack() public method

Starts playback through the user specified player.

public PlayThroughTrack ( GATPlayer player, int trackNb, float gain = 1f ) : void
player	GATPlayer
trackNb	int
gain	float
return	void

PlayThroughTrack() public method

Starts playback through the default player.

public PlayThroughTrack ( int trackNb, float gain = 1f ) : void
trackNb	int
gain	float
return	void

Release() public method

If playback is in the loop crossfade part of the envelope, the sample will loop one last time and release from the sustain index.

public Release ( ) : void
return	void

TrySetEnvelope() public method

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.

public TrySetEnvelope ( int offset, int attack, int decay, int sustain, int release, int loopCrossfade = -1 ) : bool
offset	int
attack	int
decay	int
sustain	int
release	int
loopCrossfade	int
return	bool
