/** | |||||
Manages the state of some audio and midi i/o devices. | |||||
This class keeps tracks of a currently-selected audio device, through | |||||
with which it continuously streams data from an audio callback, as well as | |||||
one or more midi inputs. | |||||
The idea is that your application will create one global instance of this object, | |||||
and let it take care of creating and deleting specific types of audio devices | |||||
internally. So when the device is changed, your callbacks will just keep running | |||||
without having to worry about this. | |||||
The manager can save and reload all of its device settings as XML, which | |||||
makes it very easy for you to save and reload the audio setup of your | |||||
application. | |||||
And to make it easy to let the user change its settings, there's a component | |||||
to do just that - the AudioDeviceSelectorComponent class, which contains a set of | |||||
device selection/sample-rate/latency controls. | |||||
To use an AudioDeviceManager, create one, and use initialise() to set it up. Then | |||||
call addAudioCallback() to register your audio callback with it, and use that to process | |||||
your audio data. | |||||
The manager also acts as a handy hub for incoming midi messages, allowing a | |||||
listener to register for messages from either a specific midi device, or from whatever | |||||
the current default midi input device is. The listener then doesn't have to worry about | |||||
re-registering with different midi devices if they are changed or deleted. | |||||
And yet another neat trick is that amount of CPU time being used is measured and | |||||
available with the getCpuUsage() method. | |||||
The AudioDeviceManager is a ChangeBroadcaster, and will send a change message to | |||||
listeners whenever one of its settings is changed. | |||||
