Overview ¶

Package audiotoolbox provides Go bindings for the AudioToolbox framework.

Record or play audio, convert formats, parse audio streams, and configure your audio session.

The AudioToolbox framework provides interfaces for recording, playback, and stream parsing. In iOS, the framework provides additional interfaces for managing audio sessions.

Essentials ¶

Porting your audio code to Apple silicon: Eliminate issues in your audio-specific code when running on Apple silicon Mac computers.

Audio Units ¶

Generating spatial audio from a multichannel audio stream: Convert 8-channel audio to 2-channel spatial audio by using a spatial mixer audio unit.
Audio Unit v3 Plug-Ins: Deliver custom audio effects, instruments, and other audio behaviors using an Audio Unit v3 app extension. (AUAudioUnit, AUAudioUnitBus, AUAudioUnitBusArray, AUAudioUnitPreset, AUAudioUnitV2Bridge)
Audio Components: Find, load, and configure audio components, such as Audio Units and audio codecs. (AudioComponent, AudioComponentInstantiationOptions, AudioComponentDescription, AudioComponentInstance, AudioComponentFlags)
Audio Unit Properties: Obtain information about the built-in mixers, equalizers, filters, effects, and other Audio Unit app extensions. (HostCallbackInfo, AUSpatialMixerAttenuationCurve, AUSpatialMixerRenderingFlags, AUSpatialMixerOutputType, AUSpatialMixerPointSourceInHeadMode)
Audio Unit Voice I/O: Configure system voice processing and respond to speech events. (AUVoiceIOMutedSpeechActivityEventListener, AUVoiceIOSpeechActivityEvent, AUVoiceIOOtherAudioDuckingConfiguration)

Playback and Recording ¶

Audio Queue Services: Connect to audio hardware and manage the recording or playback process. (AudioQueueRef, AudioQueueInputCallbackBlock, AudioQueueOutputCallbackBlock, AudioQueueTimelineRef, AudioQueueInputCallback)
Audio Services: Play short sounds or trigger a vibration effect on iOS devices with the appropriate hardware. (SystemSoundID, AudioServicesSystemSoundCompletionProc, AudioServicesPropertyID)
Music Player: Create and play a sequence of tracks, and manage aspects of playback in response to standard events. (MusicPlayer, MusicTimeStamp, MusicEventIterator, MusicEventType, ExtendedNoteOnEvent)
Anchoring sound to a window or volume: Provide unique app experiences by attaching sounds to windows and volumes in 3D space.

Audio Files and Formats ¶

Audio Format Services: Access information about audio formats and codecs. (AudioBalanceFade, AudioFormatInfo, AudioFormatListItem, AudioPanningInfo, ExtendedAudioFormatInfo)
Audio File Services: Read or write a variety of audio data to or from disk or a memory buffer. (AudioFile_ReadProc, AudioFile_WriteProc, AudioFile_GetSizeProc, AudioFile_SetSizeProc, AudioBytePacketTranslationFlags)
Extended Audio File Services: Read and write compressed files and linear PCM audio files using a simplified interface. (ExtAudioFilePacketTableInfoOverride, ExtAudioFileRef, ExtAudioFilePropertyID)
Audio File Stream Services: Parse streamed audio files as the data arrives on the user’s computer. (AudioFileStream_PropertyListenerProc, AudioFileStream_PacketsProc, AudioFileStreamPropertyID, AudioFileStreamID)
Audio File Components: Get information about audio file formats, and about files containing audio data. (AudioFileComponent, AudioFileComponentPropertyID, AudioFileComponentCreateURLProc, AudioFileComponentOpenWithCallbacksProc, AudioFileComponentOpenURLProc)
Core Audio File Format: Parse the structure of Core Audio files. (CAFAudioDescription, CAFAudioFormatListItem, CAFChunkHeader, CAFDataChunk, CAFFileHeader)

Utilities ¶

Analyzing audio performance with Instruments: Ensure a smooth and immersive audio experience in your apps using Audio System Trace.
Audio Converter Services: Convert between linear PCM audio formats, and between linear PCM and compressed formats. (AudioConverterComplexInputDataProc, AudioConverterInputDataProc, AudioConverterPrimeInfo, AudioConverterRef, AudioConverterPropertyID)
Audio Session Support: Describe the properties that you associate with audio sessions and audio routes. (AudioSessionInterruptionType)
Audio Toolbox Debugging: Obtain the internal state of Core Audio objects during the development and debugging of your code.
Workgroup Management: Coordinate the activity of custom real-time audio threads with those of the system and other processes.
Audio Codec: Translate audio data from one format to another. (AudioCodecMagicCookieInfo, AudioCodecPrimeInfo, AudioCodec, AudioCodecAppendInputBufferListProc, AudioCodecAppendInputDataProc)
Clock Utilities: Manage time-related information associated with audio playback. (CAClockRef, CAClockListenerProc, CAClockMessage, CAClockTime, CAClockTimeFormat)

Key Types ¶

AUAudioUnit - A class that defines a host’s interface to an audio unit.

type AUAudioObjectID ¶

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioObjectID

type AUAudioUnit ¶

type AUAudioUnit struct {
	objectivec.Object
}

A class that defines a host’s interface to an audio unit.

Overview ¶

Hosts can instantiate either version 3 or version 2 audio units with this class, and to some extent control whether an audio unit is instantiated in-process or in a separate extension process.

Version 3 audio units should subclass the AUAudioUnit class. Version 3 audio unit components can be registered in the following ways:

- Package the component into an app extension containing an [AudioComponents] `Info.Plist()` entry. The principal class must conform to the AUAudioUnitFactory protocol, which will typically instantiate an AUAudioUnit subclass. - Call the AUAudioUnitClass.RegisterSubclassAsComponentDescriptionNameVersion method to associate a component description with an AUAudioUnit subclass. Use the convention `:` when naming your audio unit component.

Version 2 audio units should subclass the AUAudioUnitV2Bridge class instead. Version 2 audio unit components can be registered in the following ways:

- Package the component into a component bundle containing an [AudioComponents] `Info.Plist()` entry, referring to an AudioComponentFactoryFunction function. - Call the AudioComponentRegister function to associate a component description with an AudioComponentFactoryFunction function.

A host does not need to be aware of the concrete AUAudioUnit subclass that is being instantiated. The [AUAudioUnitV2Bridge.InitWithComponentDescriptionOptionsError] method ensures that the proper subclass is used.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/canPerformOutput

func (AUAudioUnit) CanProcessInPlace ¶

func (a AUAudioUnit) CanProcessInPlace() bool

Determines whether an audio unit can process in place.

Discussion ¶

In-place processing is the ability for an audio unit to transform an input signal to an output signal in-place in the input buffer, without requiring a separate output buffer.

A host can express its desire to process in place by using null `mData` pointers in the output buffer list. If so, the audio unit may process in-place in the input buffers.

This version 3 property is partially bridged to the version 2 `kAudioUnitProperty_InPlaceProcessing` API. It is not settable in version 3.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/canProcessInPlace

func (AUAudioUnit) ChannelCapabilities ¶

func (a AUAudioUnit) ChannelCapabilities() []foundation.NSNumber

Expresses valid combinations of input and output channels.

Discussion ¶

Array elements are NSNumber values containing integers.

The array index alternates between input and output counts, in ascending order of input/output channels—for example: [0] = first input count, [1] = first output count, [2] = second input count, [3] = second output count, etc.

Positive array values specify the number of input and/or output channels supported.

Negative array values have particular meanings. An input/output value pair of `(-1, -1)` (i.e. [0] = -1, [1] = -1) indicates that any number of channels are supported, as long as they are the same number for both input and output. An input/output value pair combination of `-1` and `-2` (e.g. [0] = -1, [1] = -2) also indicates that any number of channels are supported, but without the requirement that the input and output counts are the same. A negative value less than `-2` (e.g. [0] = -16) specifies a total number of channels across every bus in that scope, regardless of how many channels are set on any particular bus.

An array value of `0` (e.g. [0] = 0) specifies that the input/output channel is not applicable (though typically only used for input channels).

The table below shows a sample selection of valid input and output channel combinations:

[Table data omitted]

This version 3 property is bridged to the version 2 `kAudioUnitProperty_SupportedNumChannels` API.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/factoryPresets

func (AUAudioUnit) FullState ¶

func (a AUAudioUnit) FullState() foundation.INSDictionary

A persistable snapshot of the audio unit’s properties and parameters, suitable for saving as a user preset.

Discussion ¶

Hosts may use this property to save and restore the state of an audio unit being used in a user preset or document. The audio unit should not persist transitory properties such as stream formats, but should save and restore all other properties.

The base class implementation of this property saves the values of all parameters currently in the parameter tree. A subclass which dynamically produces multiple variants of the parameter tree needs to be aware that the serialization method does a depth-first preorder traversal of the tree.

This version 3 property is bridged to the version 2 `kAudioUnitProperty_ClassInfo` API.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/fullState

func (AUAudioUnit) FullStateForDocument ¶

func (a AUAudioUnit) FullStateForDocument() foundation.INSDictionary

A persistable snapshot of the audio unit’s properties and parameters, suitable for saving in a user’s document.

Discussion ¶

Hosts may use this property to save and restore the state of an audio unit being used. Some state, such as a parameter value, is suitable for saving in a user preset. Other state, such as a synthesizer’s primary tuning setting, could be considered global state suitable for saving in a user document.

Subclasses that do not implement this property interface with the AUAudioUnit.FullState property instead.

This version 3 property is bridged to the version 2 `kAudioUnitProperty_ClassInfoFromDocument` API.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/fullStateForDocument

func (AUAudioUnit) IsRenderingOffline ¶

func (a AUAudioUnit) IsRenderingOffline() bool

Communicates to an audio unit that it is rendering offline.

Discussion ¶

A host should use this property when using an audio unit in a context where there are no realtime deadlines. An audio unit may respond by using a more expensive signal processing algorithm, or allowing itself to block at render time if data being generated on secondary work threads is not ready in time.

This version 3 property is bridged to the version 2 `kAudioUnitProperty_OfflineRender` API.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/isRenderingOffline

func (AUAudioUnit) IsRunning ¶

func (a AUAudioUnit) IsRunning() bool

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/isRunning

func (AUAudioUnit) Latency ¶

func (a AUAudioUnit) Latency() foundation.NSTimeInterval

The audio unit’s processing latency, in seconds.

Discussion ¶

This property reflects the delay between when an impulse arrives in the input stream vs. output stream. This should reflect the delay due to signal processing (e.g. FFTs), not as an effect (e.g. reverberation).

Note that a latency that varies with parameter settings, including bypass, is generally not useful to hosts. A host is usually only prepared to add delays before starting to render and those delays need to be fixed. A variable delay would introduce artifacts even if the host could track it. If an algorithm has a variable latency, it should be adjusted upwards to some fixed latency within the audio unit. If for some reason this is not possible, then latency could be regarded as an unavoidable consequence of the algorithm and left unreported (i.e. a value of `0`).

This version 3 property is bridged to the version 2 `kAudioUnitProperty_Latency` API.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/latency

func (AUAudioUnit) MIDIOutputBufferSizeHint ¶

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/maximumFramesToRender

func (AUAudioUnit) MessageChannelFor ¶

func (a AUAudioUnit) MessageChannelFor(channelName string) AUMessageChannel

Returns an object for bidirectional communication between an audio unit and its host.

channelName: The name of the message channel the audio unit returns.

Return Value ¶

An object that conforms to AUMessageChannel.

Discussion ¶

Message channels provide a way for custom data exchanges between an audio unit and its host. An audio unit may support multiple message channels.

The host manages the message channel object’s lifetime. Design message channel objects so they can outlive the audio unit that vended them.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/messageChannel(for:)

func (AUAudioUnit) MigrateFromPlugin ¶

func (a AUAudioUnit) MigrateFromPlugin() foundation.INSArray

This version 3 property is bridged to the version 2 HostCallback_GetBeatAndTempo and HostCallback_GetMusicalTimeLocation callback members in the `kAudioUnitProperty_HostCallbacks` API.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/musicalContextBlock

func (AUAudioUnit) OsWorkgroup ¶

func (a AUAudioUnit) OsWorkgroup() os.OSWorkgroup

The workgroup associated with the audio device underlying this Audio Unit.

Discussion ¶

Workgroups allow multiple threads to coordinate their activities for realtime operations. For Audio Units, this coordination occurs between the Audio Unit and other processes, such as the audio server and host app. The system uses the workgroup to observe the threads’ CPU usage and dynamically balance the competing considerations of power consumption and real-time rendering capacity.

This version 3 property is bridged to the version 2 KAudioOutputUnitProperty_OSWorkgroup property.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/osWorkgroup

func (AUAudioUnit) OutputBusses ¶

func (a AUAudioUnit) OutputBusses() IAUAudioUnitBusArray

An array containing the audio unit’s output connection points.

Discussion ¶

func (AUAudioUnit) ParameterTree ¶

func (a AUAudioUnit) ParameterTree() IAUParameterTree

An audio unit’s parameters, organized in a tree hierarchy.

Discussion ¶

Hosts can fetch this property to discover a unit’s parameters. KVO notifications are issued on this member to notify the host of changes to the set of available parameters.

Subclasses should implement this property to expose parameters to hosts. They should then cache as much data as possible and send KVO notifications on this property when altering the structure of the tree or the static information of parameters.

This version 3 property is similar to the version 2 `kAudioUnitProperty_ParameterList` and `kAudioUnitProperty_ParameterInfo` APIs.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/parameterTree

func (AUAudioUnit) ParametersForOverviewWithCount ¶

func (AUAudioUnit) RemoveRenderObserver ¶

func (a AUAudioUnit) RemoveRenderObserver(token int)

Removes an observer block previously added to the render cycle.

token: The token associated with the block.

Discussion ¶

This version 3 property is bridged to the version 2 AudioUnitRemoveRenderNotify API.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/removeRenderObserver(_:)

func (AUAudioUnit) RenderBlock ¶

func (a AUAudioUnit) RenderBlock() IntAudioUnitRenderActionFlagsHandler

The block that hosts use to ask the audio unit to render audio.

Discussion ¶

Before invoking an audio unit’s rendering functionality, a host should fetch this block and cache the result. The block can then be called from a realtime context without the possibility of blocking and causing an overload at the Core Audio HAL level.

This block will call a subclass’s AUAudioUnit.InternalRenderBlock implementation, providing all realtime events scheduled for the current render time interval, bracketed by calls to any render observers. Subclasses should override their AUAudioUnit.InternalRenderBlock implementation, not this property.

This version 3 property is bridged to the version 2 AudioUnitRender API.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/renderBlock

func (AUAudioUnit) RenderContextObserver ¶

func (a AUAudioUnit) RenderContextObserver() conststructAudioUnitRenderContextHandler

The block that the system calls when the rendering context changes.

Determines whether the audio unit has allocated render resources.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/renderResourcesAllocated

func (AUAudioUnit) Reset ¶

func (a AUAudioUnit) Reset()

Resets transitory rendering state to its initial state.

Discussion ¶

Hosts should call this at the point of a discontinuity in the input stream being provided to an audio unit—for example, when seeking forward or backward within a track. In response, audio units should clear delay lines, filters, etc. Subclasses should call the superclass implementation.

This version 3 method is bridged to the version 2 AudioUnitReset API, in the global scope.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/reset()

func (AUAudioUnit) SaveUserPresetError ¶

func (a AUAudioUnit) SaveUserPresetError(userPreset IAUAudioUnitPreset) (bool, error)

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/saveUserPreset(_:)

func (AUAudioUnit) ScheduleMIDIEventBlock ¶

func (a AUAudioUnit) ScheduleMIDIEventBlock() AUScheduleMIDIEventBlock

A block used to schedule MIDI events.

Discussion ¶

As with the render block, a host should fetch this block before beginning to render, if it intends to schedule MIDI events.

This property is implemented in the AUAudioUnit base class. If the audio unit is not a music device or effect, this property is `nil`.

Subclasses should not override this property. When hosts schedule events via this block, they are delivered to the audio unit via the list of render events delivered to the AUAudioUnit.InternalRenderBlock implementation.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/scheduleMIDIEventBlock

func (AUAudioUnit) ScheduleMIDIEventListBlock ¶

func (a AUAudioUnit) ScheduleMIDIEventListBlock() IntInt64Handler

func (AUAudioUnit) ScheduleParameterBlock ¶

func (a AUAudioUnit) ScheduleParameterBlock() Int64Uint32Uint64Float32Handler

The block that hosts use to schedule parameters.

Discussion ¶

As with the render block, a host should fetch this block before beginning to render, if it intends to schedule parameters.

The block is safe to call from any thread context, including realtime audio render threads. Subclasses should not override this; it is implemented in the base class and will schedule the events to be provided to the AUAudioUnit.InternalRenderBlock implementation

This version 3 property is bridged to the version 2 AudioUnitScheduleParameters API.

See: https://developer.apple.com/documentation/AudioToolbox/AUAudioUnit/scheduleParameterBlock

func (AUAudioUnitBus) ContextPresentationLatency ¶

func (a AUAudioUnitBus) ContextPresentationLatency() foundation.NSTimeInterval

Information about latency in the audio unit’s processing context.

Discussion ¶

A host may set this property to describe the presentation latency, in seconds, of its input and/or output audio data. A value of `0` means either no latency or unknown latency.

A host should set this property on each active bus, since, for example, the audio routing path to each of multiple output busses may differ. The meaning of this property’s value differs between input and output busses, as described below:

- For input busses, this value describes how long ago the audio arriving on this bus was acquired.

For example, when reading from a file to the first audio unit in a chain, the input presentation latency is zero. For audio input from a device, this initial input latency is the presentation latency of the device itself (i.e. the device’s offset and latency). A second chained audio unit’s input presentation latency is the input presentation latency of the first unit, plus the processing latency of the first unit.

- For output busses, this value describes how long it will be before the output audio of an audio unit is presented.

For example, when writing to a file, the output presentation latency of the last audio unit in a chain is zero. When the audio from that audio unit is to be played to a device, then that initial presentation latency will be the presentation latency of the device itself (i.e. the I/O buffer size) plus the device’s safety offset and latency. A previously chained audio unit’s output presentation latency is the last unit’s presentation latency plus its processing latency.

For a given audio unit anywhere within a mixing graph, the input and output presentation latencies describe to that unit how long from the moment of generation it has taken for its input to arrive, and how long it will take for its output to be presented.

This version 3 property is bridged to the version 2 `kAudioUnitProperty_PresentationLatency` API.

func (p AUParameterNode) Init() AUParameterNode

Init initializes the instance.

func (AUParameterNode) KeyPath ¶

func (p AUParameterNode) KeyPath() string

A key path generated by concatenating the identifiers of the parameter and its parents.

Discussion ¶

When recording parameter values, hosts should bind to the parameter key path (unless an audio unit specifically documents that its parameter addresses are stable and persistent). The individual node identifiers in a key path are separated by periods (`.`). Passing a node’s key path to a parameter tree’s value(forKeyPath:) method returns the same node.

Adds an observer for a single parameter or all parameters in a group.

observer: A block called after the value of a parameter has changed.

Return Value ¶

A token which can be passed to the AUParameterNode.RemoveParameterObserver or AUParameter.SetValueOriginator methods.

Discussion ¶

An audio unit view can use an observer to be notified of changes to a single parameter or all parameters in a group. These callbacks are throttled so as to limit the rate of redundant notifications in the case of frequent changes to a single parameter.

This block is called in an arbitrary thread context and it is responsible for thread-safety. It must not make any calls to add or remove other observers, including itself, as this will deadlock.

An audio unit should interact with the parameter node via the AUParameterNode.ImplementorValueObserver and AUParameterNode.ImplementorValueProvider properties.

See: https://developer.apple.com/documentation/AudioToolbox/AUParameterNode/token(byAddingParameterObserver:)

func (AUParameterNode) TokenByAddingParameterRecordingObserver ¶

func (p AUParameterNode) TokenByAddingParameterRecordingObserver(observer Int64AURecordedParameterEventHandler) AUParameterObserverToken

Adds a recording observer for a single parameter or all parameters in a group.

observer: A block called to record parameter changes.

Return Value ¶

A token which can be passed to the AUParameterNode.RemoveParameterObserver or AUParameter.SetValueOriginator methods.

Discussion ¶

A host can use a recording observer to capture a series of changes to a parameter value as generated by a UI gesture. Unlike a non-recording observer, these callbacks are not throttled.

This block is called in an arbitrary thread context and it is responsible for thread-safety. It must not make any calls to add or remove other observers, including itself, as this will deadlock.

An audio unit should interact with the parameter node via the AUParameterNode.ImplementorValueObserver and AUParameterNode.ImplementorValueProvider properties.

See: https://developer.apple.com/documentation/AudioToolbox/AUParameterNode/token(byAddingParameterRecordingObserver:)

	AUParameterGroup
}

An object that represents a top-level group node that contains all of an audio unit’s parameters.

Overview ¶

An audio unit’s parameters are organized into a tree containing groups and parameters (groups may be nested).

The parameter tree is KVO-compliant. An audio unit may choose to dynamically rearrange the tree; when doing so, it must issue a KVO notification on the audio unit’s AUAudioUnit.ParameterTree property.

Obtaining Tree Parameters ¶

AUParameterTree.ParameterWithAddress: Searches the tree for a parameter with a specific address.

Discussion ¶

Version 2 audio units publish parameters identified by a parameter ID, scope, and element. A host that knows that it is dealing with a version 2 audio unit can locate parameters using this method—for example, for the Apple-supplied system audio units.
