Here is the call graph for this function:

◆ ProcessFinalize()

bool PerTrackEffect::Instance::ProcessFinalize ( )

Called at end of destructive processing, for each (mono/stereo) track Default implementation does nothing, returns true This may be called during stack unwinding:

Implements EffectInstanceEx.

Reimplemented in StatefulPerTrackEffect::Instance, VSTEffectInstance, VST3Instance, and EffectReverb::Instance.

Definition at line 48 of file PerTrackEffect.cpp.

50 return true;

◆ ProcessInitialize()

bool PerTrackEffect::Instance::ProcessInitialize ( EffectSettings settings,
double  sampleRate,
ChannelNames  chanMap 

Called at start of destructive processing, for each (mono/stereo) track Default implementation does nothing, returns true

chanMapnull or array terminated with ChannelNameEOL. Do not retain the pointer
GetAudioInCount() and GetAudioOutCount() are well defined

Implements EffectInstanceEx.

Reimplemented in EffectReverb::Instance, StatefulPerTrackEffect::Instance, VSTEffectInstance, VST3Instance, and EffectWahwah::Instance.
