Class AVAudioIONode

  • All Implemented Interfaces:
    NSObject
    Direct Known Subclasses:
    AVAudioInputNode, AVAudioOutputNode
    public class AVAudioIONode
extends AVAudioNode
    AVAudioIONode Base class for a node that performs audio input or output in the engine. When the engine is configured to render to/from an audio device, on macOS, AVAudioInputNode and AVAudioOutputNode communicate with the system's default input and output devices. On iOS, they communicate with the devices appropriate to the app's AVAudioSession category and other configuration, also considering the user's actions such as connecting/disconnecting external devices. In the manual rendering mode, the AVAudioInputNode and AVAudioOutputNode perform the input and output in the engine, in response to client's request.

      • setVoiceProcessingEnabledError

        public boolean setVoiceProcessingEnabledError​(boolean enabled,
                                              org.moe.natj.general.ptr.Ptr<NSError> outError)
        setVoiceProcessingEnabled:error: Enable or disable voice processing on the IO node. If enabled, the input node does signal processing on the incoming audio (taking out any of the audio that is played from the device at a given time from the incoming audio). Disabling this mode on either of the IO nodes automatically disabled it on the other IO node. Voice processing requires both input and output nodes to be in the voice processing mode. Enabling this mode on either of the IO nodes automatically enables it on the other IO node. Voice processing is only supported when the engine is rendering to the audio device and not in the manual rendering mode. Voice processing can only be be enabled or disabled when the engine is in a stopped state. The output format of the input node and the input format of the output node have to be the same and they can only be changed when the engine is in a stopped state.
        Parameters:
        enabled - Whether voice processing is to be enabled.
        outError - On exit, if the IO node cannot enable or diable voice processing, a description of the error
        Returns:
        YES for success
