Detailed Description

An object that creates and plays a standalone instance of an AudioProcessor.

The object will create your processor using the same createPluginFilter() function that the other plugin wrappers use, and will run it through the computer's audio/MIDI devices using AudioDeviceManager and AudioProcessorPlayer.

Constructor & Destructor Documentation

◆ StandalonePluginHolder()

StandalonePluginHolder::StandalonePluginHolder	(	PropertySet *	settingsToUse,
		bool	takeOwnershipOfSettings = true,
		const String &	preferredDefaultDeviceName = String(),
		const AudioDeviceManager::AudioDeviceSetup *	preferredSetupOptions = nullptr,
		const Array< PluginInOuts > &	channels = Array<PluginInOuts>(),
		bool	shouldAutoOpenMidiDevices = true )

Creates an instance of the default plugin.

The settings object can be a PropertySet that the class should use to store its settings - the takeOwnershipOfSettings indicates whether this object will delete the settings automatically when no longer needed. The settings can also be nullptr.

A default device name can be passed in.

Preferably a complete setup options object can be used, which takes precedence over the preferredDefaultDeviceName and allows you to select the input & output device names, sample rate, buffer size etc.

In all instances, the settingsToUse will take precedence over the "preferred" options if not null.

◆ valueChanged()

void StandalonePluginHolder::valueChanged ( Value & value )

overridevirtual

Called when a Value object is changed.

Note that the Value object passed as a parameter may not be exactly the same object that you registered the listener with - it might be a copy that refers to the same underlying ValueSource. To find out, you can call Value::refersToSameSourceAs().

Implements Value::Listener.
