Functions

func AVAudioApplicationInputMuteStateChangeNotification 

func AVAudioApplicationInputMuteStateChangeNotification() uintptr

@brief Notification sent to registered listeners when the application's input is muted or unmuted. Check the notification's userInfo dictionary for the mute state `AVAudioApplicationMuteStateKey` which will have a boolean value 0 for unmuted or value 1 for muted. @note this notification will only be dispatched for state changes when there is an active record session (i.e. record or playAndRecord category). Setting the `inputMuted` state while the record session is not active is allowed and will be stored, but it will not trigger a notification for the state change. When the record session subsequently goes active, the `inputMuted` state will be applied, and this notification will be dispatched with the latest input muted state.

func AVAudioApplicationMuteStateKey 

func AVAudioApplicationMuteStateKey() uintptr

Keys for AVAudioApplicationInputMuteStateChangeNotification Value is NSNumber type with boolean value 0 for unmuted or value 1 for muted (samples zeroed out)

func AVAudioApplicationRequestRecordPermissionWithCompletionHandler

func AVAudioEngineConfigurationChangeNotification 

func AVAudioEngineConfigurationChangeNotification() uintptr

@constant AVAudioEngineConfigurationChangeNotification @abstract A notification generated on engine configuration changes when rendering to/from an audio device. Register for this notification on your engine instances, as follows: ``` [[NSNotificationCenter defaultCenter] addObserver: myObject selector: @selector(handleInterruption:) name: AVAudioEngineConfigurationChangeNotification object: engine]; ``` When the engine's I/O unit observes a change to the audio input or output hardware's channel count or sample rate, the engine stops itself (see `AVAudioEngine(stop)`), and issues this notification. The nodes remain attached and connected with previously set formats. However, the app must reestablish connections if the connection formats need to change (e.g. in an input node chain, connections must follow the hardware sample rate, while in an output only chain, the output node supports rate conversion). Note that the engine must not be deallocated from within the client's notification handler because the callback happens on an internal dispatch queue and can deadlock while trying to synchronously teardown the engine.

func AVAudioSessionInterruptionWasSuspendedKey 

func AVAudioSessionInterruptionWasSuspendedKey() uintptr

Only present in begin interruption events, where the interruption is a direct result of the application being suspended by the operating sytem. Value is a boolean NSNumber, where a true value indicates that the interruption is the result of the application being suspended, rather than being interrupted by another audio session. Starting in iOS 10, the system will deactivate the audio session of most apps in response to the app process being suspended. When the app starts running again, it will receive the notification that its session has been deactivated by the system. Note that the notification is necessarily delayed in time, due to the fact that the application was suspended at the time the session was deactivated by the system and the notification can only be delivered once the app is running again.

When compressing to a format which supports it (such as APAC), the audio sync packet frequency indicates the distance in packets between two sync packets, with non-sync packets between. This is useful to set when saving compressed packets to a file and efficient random access is desired. Note: Separating sync packets by at least one second of encoded audio (e.g. 75 packets) is recommended.

func (*AVAudioEngine) InputNode 

func (o *AVAudioEngine) InputNode() *AVAudioInputNode

@property inputNode @abstract The engine's singleton input node. Audio input is performed via an input node. The engine creates a singleton on demand when this property is first accessed. To receive input, connect another node from the output of the input node, or create a recording tap on it. When the engine is rendering to/from an audio device, the AVAudioSesssion category and/or availability of hardware determine whether an app can perform input. Check for the input node's input format (i.e. hardware format) for non-zero sample rate and channel count to see if input is enabled. Trying to perform input through the input node when it is not enabled or available will cause the engine to throw an error (when possible) or an exception. Note that if the engine has at any point previously had its inputNode enabled and permission to record was granted, then any time the engine is running, the mic-in-use indicator will appear. For applications which may need to dynamically switch between output-only and input-output modes, it may be advantageous to use two engine instances. In manual rendering mode, the input node can be used to synchronously supply data to the engine while it is rendering (see `AVAudioInputNode(setManualRenderingInputPCMFormat:inputBlock:)`.

func (*AVAudioEngine) IsAutoShutdownEnabled 

func (o *AVAudioEngine) IsAutoShutdownEnabled() bool

@property autoShutdownEnabled @abstract When auto shutdown is enabled, the engine can start and stop the audio hardware dynamically, to conserve power. This is the enforced behavior on watchOS and can be optionally enabled on other platforms. To conserve power, it is advised that the client pause/stop the engine when not in use. But when auto shutdown is enabled, the engine will stop the audio hardware if it was running idle for a certain duration, and restart it later when required. Note that, because this operation is dynamic, it may affect the start times of the source nodes (e.g. `AVAudioPlayerNode`), if the engine has to resume from its shutdown state. On watchOS, auto shutdown is always enabled. On other platforms, it is disabled by default, but the client can enable it if needed. This property is applicable only when the engine is rendering to/from an audio device. If the value is changed when the engine is in manual rendering mode, it will take effect whenever the engine is switched to render to/from the audio device.

func (*AVAudioEngine) IsInManualRenderingMode 

func (o *AVAudioEngine) IsInManualRenderingMode() bool

@property isInManualRenderingMode @abstract Whether or not the engine is operating in manual rendering mode, i.e. not connected to an audio device and rendering in response to the requests from the client

func (*AVAudioEngine) IsRunning 

func (o *AVAudioEngine) IsRunning() bool

@property running @abstract The engine's running state.

func (*AVAudioEngine) MainMixerNode 

func (o *AVAudioEngine) MainMixerNode() *AVAudioMixerNode

@property mainMixerNode @abstract The engine's optional singleton main mixer node. The engine will construct a singleton main mixer and connect it to the outputNode on demand, when this property is first accessed. You can then connect additional nodes to the mixer. If the client has never explicitly set the connection format between the mainMixerNode and the outputNode, the engine will always set/update the format to track the format of the outputNode on (re)start, even after an AVAudioEngineConfigurationChangeNotification. Otherwise, it's the client's responsibility to set/update this connection format after an AVAudioEngineConfigurationChangeNotification. By default, the mixer's output format (sample rate and channel count) will track the format of the output node. You may however make the connection explicitly with a different format.

func (*AVAudioEngine) ManualRenderingBlock 

func (o *AVAudioEngine) ManualRenderingBlock() objc.Block

@property manualRenderingBlock @abstract Block to render the engine operating in manual rendering mode This block based render call must be used to render the engine when operating in `AVAudioEngineManualRenderingModeRealtime`. In this mode, the engine operates under realtime constraints and will not make any blocking call (e.g. calling libdispatch, blocking on a mutex, allocating memory etc.) while rendering. Before invoking the rendering functionality, client must fetch this block and cache the result. The block can then be called from a realtime context, without any possibility of blocking. When rendering in `AVAudioEngineManualRenderingModeOffline`, either this block based render call or `renderOffline:toBuffer:error:` ObjC method can be used. All the rules outlined in `renderOffline:toBuffer:error:` are applicable here as well.

func (*AVAudioEngine) ManualRenderingFormat 

func (o *AVAudioEngine) ManualRenderingFormat() *AVAudioFormat

@property manualRenderingFormat @abstract The render format of the engine in manual rendering mode. Querying this property when the engine is not in manual rendering mode will return an invalid format, with zero sample rate and channel count.

func (*AVAudioEngine) ManualRenderingMaximumFrameCount 

func (o *AVAudioEngine) ManualRenderingMaximumFrameCount() uint32

@property manualRenderingMaximumFrameCount @abstract The maximum number of PCM sample frames the engine can produce in any single render call in the manual rendering mode. Querying this property when the engine is not in manual rendering mode will return zero.

func (*AVAudioEngine) ManualRenderingMode 

func (o *AVAudioEngine) ManualRenderingMode() AVAudioEngineManualRenderingMode

@property manualRenderingMode @abstract The manual rendering mode configured on the engine This property is meaningful only when the engine is operating in manual rendering mode, i.e. when `isInManualRenderingMode` returns true.

func (*AVAudioEngine) ManualRenderingSampleTime 

func (o *AVAudioEngine) ManualRenderingSampleTime() int64

@property manualRenderingSampleTime @abstract Indicates where the engine is on its render timeline in manual rendering mode. The timeline in manual rendering mode starts at a sample time of zero, and is in terms of the render format's sample rate. Resetting the engine (see `reset`) will reset the timeline back to zero.

func (*AVAudioEngine) MusicSequence 

func (o *AVAudioEngine) MusicSequence() unsafe.Pointer

@property musicSequence @abstract The MusicSequence previously attached to the engine (if any).

func (*AVAudioEngine) OutputConnectionPointsForNodeOutputBus 

func (o *AVAudioEngine) OutputConnectionPointsForNodeOutputBus(node *AVAudioNode, bus uint) *foundation.NSArray[*AVAudioConnectionPoint]

Returns connection information about a node’s output bus.

func (*AVAudioEngine) OutputNode 

func (o *AVAudioEngine) OutputNode() *AVAudioOutputNode

@property outputNode @abstract The engine's singleton output node. Audio output is performed via an output node. The engine creates a singleton on demand when this property is first accessed. Connect another node to the input of the output node, or obtain a mixer that is connected there by default, using the "mainMixerNode" property. When the engine is rendering to/from an audio device, the AVAudioSesssion category and/or availability of hardware determine whether an app can perform output. Check the output format of output node (i.e. hardware format) for non-zero sample rate and channel count to see if output is enabled. Trying to perform output through the output node when it is not enabled or available will cause the engine to throw an error (when possible) or an exception. In manual rendering mode, the output format of the output node will determine the render format of the engine. It can be changed through `enableManualRenderingMode:format:maximumFrameCount:error:`.

func (o *AVAudioNode) OutputPresentationLatency() float64

@property outputPresentationLatency @abstract The maximum render pipeline latency downstream of the node, in seconds. @discussion This describes the maximum time it will take for the audio at the output of a node to be presented. For instance, the output presentation latency of the output node in the engine is: - zero in manual rendering mode - the presentation latency of the device itself when rendering to an audio device (see `AVAudioIONode(presentationLatency)`) The output presentation latency of a node connected directly to the output node is the output node's presentation latency plus the output node's processing latency (see `latency`). For a node which is exclusively in the input node chain (i.e. not connected to engine's output node), this property reflects the latency for the output of this node to be presented at the output of the terminating node in the input chain. A value of zero indicates either an unknown or no latency. Note that this latency value can change as the engine is reconfigured (started/stopped, connections made/altered downstream of this node etc.). So it is recommended not to cache this value and fetch it whenever it's needed.

@property floatChannelData @abstract Access the buffer's float audio samples. @discussion floatChannelData returns pointers to the buffer's audio samples if the buffer's format is 32-bit float, or nil if it is another format. The returned pointer is to format.channelCount pointers to float. Each of these pointers is to "frameLength" valid samples, which are spaced by "stride" samples. If format.interleaved is false (as with the standard deinterleaved float format), then the pointers will be to separate chunks of memory. "stride" is 1. If format.interleaved is true, then the pointers will refer into the same chunk of interleaved samples, each offset by 1 frame. "stride" is the number of interleaved channels.

func (o *AVSpeechSynthesisProviderAudioUnit) SpeechSynthesisOutputMetadataBlock() objc.Block

@brief A property set by the host that is called by the audio unit to supply metadata for a speech request. @discussion A synthesizer should call this method when it has produced relevant data to the audio buffers it is sending back to the host. In some cases speech output may be delayed until these markers are delivered. For example, word highlighting depends on marker data from synthesizers in order to properly time which words are highlighted. Many speech synthesizers generate this information on the fly, while synthesizing the audio. The array of markers can reference future audio buffers that have yet to be delivered. There may be cases in which marker data is not fully known until further audio processing is done. In these cases, and other casers where marker data has changed, calling this block with marker data that contains perviously delivered audio buffer ranges will replace that audio buffer range's marker data, as it will be considered stale.
