Member Function Documentation

◆ MakeInstance()

virtual std::shared_ptr< EffectInstance > EffectInstanceFactory::MakeInstance ( ) const

pure virtual

Make an object maintaining short-term state of an Effect.

One effect may have multiple instances extant simultaneously. Instances have state, may be implemented in foreign code, and are temporary, whereas EffectSettings represents persistent effect state that can be saved and reloaded from files.

Parameters

settings may be assumed to have a lifetime enclosing the instance's

Postcondition: true (no promises that the result isn't null)

Implemented in AudioUnitEffect, EffectDtmf, EffectEcho, StatefulEffect, LadspaEffect, LV2Effect, EffectReverb, StatefulPerTrackEffect, VSTEffect, VST3Effect, and EffectWahwah.

Referenced by EffectBase::DoEffect(), RealtimeEffectState::EnsureInstance(), RealtimeEffectState::GetInstance(), EffectUIHost::InitializeInstance(), EffectBase::Preview(), and PerTrackEffect::ProcessPass().
