ContextPulseAudio /

Creates and returns a platform-specific OutputDeviceNode , which delivers audio to the hardware output device specified by device .

Creates and returns a platform-specific InputDeviceNode , which captures audio from the hardware input device specified by device .

TODO: this is a private class, remove.

Interface for creating new Node 's of type NodeT , which is owned by this Context . All Node 's must be created using the Context .

Interface for creating a new Node of type NodeT , which is owned by this Context . All Node 's must be created using the Context .

Sets the new output of this Context to output . You should do this before making any connections because when Node 's are initialized they use the format of the OutputNode to configure their buffers.

Returns the OutputNode for the Context (currently always an OutputDeviceNode that sends audio to your speakers). This can be thought of as the 'heartbeat', it is the one who initiates the pulling and processing of all other Node 's in the audio graph. note If the output has not already been set, it is the default OutputDeviceNode .

Enables audio processing. Effectively the same as calling getOutput() -> enable()

Enables audio processing. Effectively the same as calling getOutput() -> disable()

start / stop audio processing via boolean

Returns whether or not this Context is current enabled and processing audio.

Called by node when it's connections have changed. Default implementation is empty.

Returns the samplerate of this Context , which is governed by the current OutputNode .

Returns the number of frames processed in one block by this Node , which is governed by the current OutputNode .

Returns the total number of frames that have been processed in the dsp loop.

Returns the total number of seconds that have been processed in the dsp loop.

Initializes node , ensuring that Node::initialze() gets called and that its internal buffers are ready for processing. Useful for initializing a heavy Node at an opportune time so as to not cause audio drop-outs or UI snags.

Un-initializes node , ensuring that Node::uninitialze() gets called.

Initialize all Node 's related by this Context .

Uninitialize all Node 's related by this Context .

Disconnect all Node 's related by this Context .

Add node to the list of auto-pulled nodes, who will have their Node::pullInputs() method called after a OutputDeviceNode implementation finishes pulling its inputs.

Callers on the non-audio thread must synchronize with getMutex() .

Remove node from the list of auto-pulled nodes.

Callers on the non-audio thread must synchronize with getMutex() .

Schedule node to be enabled or disabled with with func on the audio thread, to be called at when seconds measured against getNumProcessedSeconds() . If callFuncBeforeProcess is true, then func will be called at the beginning of the processing block, if false will be called at the end.

Should be called from the user thread. Currently only one event can be scheduled on a node at a time. node is owned until the scheduled event completes.

Immediately cancels any events scheduled with scheduleEvent() .

Deprecated

use scheduleEvent() instead.

Returns the mutex used to synchronize the audio thread. This is also used internally by the Node class when making connections.

Returns true if the current thread is the thread used for audio processing, false otherwise.

OutputNode implementations should call this before each rendering block.

OutputNode implementations should call this after each rendering block.

Returns the time in seconds spent during the last process loop.

Returns a string representation of the Node graph for debugging purposes.

Returns the master Context that manages hardware I/O and real-time processing, which is platform specific. If none is available, returns null .

Returns the platform-specific DeviceManager singleton instance, which is platform specific. If none is available, returns null .

Allows the user to set the master Context and DeviceManager , overriding the defaults.
