Types

• class Signal1

  Signal support.

• enum SpeakerMode

Type members

• static var busCount: Int32

  Number of available audio buses.

• static var inputDevice: String

  Name of the current device for audio input (see getInputDeviceList). On systems with multiple audio inputs (such as analog, USB and HDMI audio), this can be used to select the audio input device. The value "Default" will record audio on the system-wide default audio input. If an invalid device name is set, the value will be reverted back to "Default".

• static var outputDevice: String

  Name of the current device for audio output (see getOutputDeviceList). On systems with multiple audio outputs (such as analog, USB and HDMI audio), this can be used to select the audio output device. The value "Default" will play audio on the system-wide default audio output. If an invalid device name is set, the value will be reverted back to "Default".

• static var playbackSpeedScale: Double

  Scales the rate at which audio is played (i.e. setting it to 0.5 will make the audio be played at half its speed).

• static var shared: AudioServer

  The shared instance of this class

• static func addBus(atPosition: Int32)

  Adds a bus at atPosition.

• static func addBusEffect(busIdx: Int32, effect: AudioEffect?, atPosition: Int32)

  Adds an AudioEffect effect to the bus busIdx at atPosition.

• static func generateBusLayout() -> AudioBusLayout?

  Generates an AudioBusLayout using the available buses and effects.

• static func getBusChannels(busIdx: Int32) -> Int32

  Returns the number of channels of the bus at index busIdx.

• static func getBusEffect(busIdx: Int32, effectIdx: Int32) -> AudioEffect?

  Returns the AudioEffect at position effectIdx in bus busIdx.

• static func getBusEffectCount(busIdx: Int32) -> Int32

  Returns the number of effects on the bus at busIdx.

• static func getBusEffectInstance(busIdx: Int32, effectIdx: Int32, channel: Int32) -> AudioEffectInstance?

  Returns the AudioEffectInstance assigned to the given bus and effect indices (and optionally channel).

• static func getBusIndex(busName: StringName) -> Int32

  Returns the index of the bus with the name busName. Returns -1 if no bus with the specified name exist.

• static func getBusName(busIdx: Int32) -> String

  Returns the name of the bus with the index busIdx.

• static func getBusPeakVolumeLeftDb(busIdx: Int32, channel: Int32) -> Double

  Returns the peak volume of the left speaker at bus index busIdx and channel index channel.

• static func getBusPeakVolumeRightDb(busIdx: Int32, channel: Int32) -> Double

  Returns the peak volume of the right speaker at bus index busIdx and channel index channel.

• static func getBusSend(busIdx: Int32) -> StringName

  Returns the name of the bus that the bus at index busIdx sends to.

• static func getInputDeviceList() -> PackedStringArray

  Returns the names of all audio input devices detected on the system.

• static func getMixRate() -> Double

  Returns the sample rate at the output of the AudioServer.

• static func getOutputDeviceList() -> PackedStringArray

  Returns the names of all audio output devices detected on the system.

• static func getOutputLatency() -> Double

  Returns the audio driver’s effective output latency. This is based on ProjectSettings/audio/driver/outputLatency, but the exact returned value will differ depending on the operating system and audio driver.

• static func getSpeakerMode() -> AudioServer.SpeakerMode

  Returns the speaker configuration.

• static func getTimeSinceLastMix() -> Double

  Returns the relative time since the last mix occurred.

• static func getTimeToNextMix() -> Double

  Returns the relative time until the next mix occurs.

• static func isBusBypassingEffects(busIdx: Int32) -> Bool

  If true, the bus at index busIdx is bypassing effects.

• static func isBusEffectEnabled(busIdx: Int32, effectIdx: Int32) -> Bool

  If true, the effect at index effectIdx on the bus at index busIdx is enabled.

• static func isBusMute(busIdx: Int32) -> Bool

  If true, the bus at index busIdx is muted.

• static func isBusSolo(busIdx: Int32) -> Bool

  If true, the bus at index busIdx is in solo mode.

• static func lock()

  Locks the audio driver’s main loop.

• static func moveBus(index: Int32, toIndex: Int32)

  Moves the bus from index index to index toIndex.

• static func removeBus(index: Int32)

  Removes the bus at index index.

• static func removeBusEffect(busIdx: Int32, effectIdx: Int32)

  Removes the effect at index effectIdx from the bus at index busIdx.

• static func setBusBypassEffects(busIdx: Int32, enable: Bool)

  If true, the bus at index busIdx is bypassing effects.

• static func setBusEffectEnabled(busIdx: Int32, effectIdx: Int32, enabled: Bool)

  If true, the effect at index effectIdx on the bus at index busIdx is enabled.

• static func setBusLayout(AudioBusLayout?)

  Overwrites the currently used AudioBusLayout.

• static func setBusMute(busIdx: Int32, enable: Bool)

  If true, the bus at index busIdx is muted.

• static func setBusName(busIdx: Int32, name: String)

  Sets the name of the bus at index busIdx to name.

  Connects the output of the bus at busIdx to the bus named send.

• static func setBusSolo(busIdx: Int32, enable: Bool)

  If true, the bus at index busIdx is in solo mode.

• static func setBusVolumeDb(busIdx: Int32, volumeDb: Double)

  Sets the volume of the bus at index busIdx to volumeDb.

• static func setEnableTaggingUsedAudioStreams(enable: Bool)
• static func swapBusEffects(busIdx: Int32, effectIdx: Int32, byEffectIdx: Int32)

  Swaps the position of two effects in bus busIdx.
