AudioEffectInstance

继承： RefCounted < Object

派生： AudioEffectSpectrumAnalyzerInstance

Manipulates the audio it receives for a given effect.

描述

An audio effect instance manipulates the audio it receives for a given effect. This instance is automatically created by an AudioEffect when it is added to a bus, and should usually not be created directly. If necessary, it can be fetched at run-time with AudioServer.get_bus_effect_instance.

方法
void_process ( src_buffer: const void*, dst_buffer: AudioFrame*, frame_count: int ) virtual1
bool_process_silence ( ) virtual1 const2

方法说明

void _process ( src_buffer: const void*, dst_buffer: AudioFrame*, frame_count: int ) virtual1

Called by the AudioServer to process this effect. When _process_silence is not overridden or it returns false, this method is called only when the bus is active.

Note: It is not useful to override this method in GDScript or C#. Only GDExtension can take advantage of it.

bool _process_silence ( ) virtual1 const2

Override this method to customize the processing behavior of this effect instance.

Should return true to force the AudioServer to always call _process, even if the bus has been muted or cannot otherwise be heard.
