You use audio nodes to generate audio signals, process them, and perform audio input and output.
You create each audio node separately and attach it to the audio engine. You can perform all audio node operations during runtime—connecting them, disconnecting them, and removing them—with only minor limitations:
- Reconnect audio nodes only when they are upstream of a mixer..
- If you remove an audio node that has differing input and output channel counts, or which is a mixer, the result will likely be a broken graph.

An operation that can’t be performed because the engine hasn’t stopped running.
An operation that can’t be performed because the engine is not in manual rendering mode or the right variant of it.
An operation that can’t be performed because the engine hasn’t started running.
An engine that operates in an offline mode.
An engine that operates under real-time constraints and doesn't make blocking calls while rendering.
Manual Rendering Status
An operation that can't be performed under current conditions; the client can try again later.
A problem that occurred during rendering, resulting in no data being returned.
A condition in which not enough input data was returned by the input node to satisfy the render request at the time of the request.
A status that indicates that all of the requested data was returned successfully.
