Accessors

  • get duration(): number
  • Retrieves the duration of the sound in seconds. If the sound is based on an AudioBuffer, it returns the duration of the buffer. Otherwise, if the sound has not been played and is a MediaElementSource, it returns NaN, indicating that the duration is unknown or not applicable.

    Returns number

    The duration of the sound in seconds.

  • get isPlaying(): boolean
  • Returns a boolean indicating whether the object is currently playing. an object is playing if any of its playbacks are currently playing.

    Returns boolean

    True if the object is playing, false otherwise.

  • get position(): Position
  • Retrieves the current 3D spatial position of the sound in the audio context. The position is returned as an array of three values[x, y, z].

    Returns Position

    The current position of the sound.

  • set position(position): void
  • Sets the 3D spatial position of the sound in the audio context. The position is an array of three values[x, y, z]. This method updates the position of all active playbacks of the sound.

    Parameters

    • position: Position

      The new position of the sound.

    Returns void

  • get stereoPan(): null | number
  • Returns null | number

  • set stereoPan(value): void
  • Parameters

    • value: number

    Returns void

  • get volume(): number
  • Returns number

  • set volume(volume): void
  • Parameters

    • volume: number

    Returns void

Methods

  • Adds a BiquadFilterNode to the container's filter chain. Filters are cloned when creating new playbacks - existing playbacks are not affected. Each playback gets independent filter instances for isolated processing.

    Parameters

    Returns void

  • Parameters

    • connection: any

    Returns any

  • Returns void

  • Clones the current Sound instance, creating a deep copy with the option to override specific properties. This method allows for the creation of a new, independent Sound instance based on the current one, with the flexibility to modify certain attributes through the overrides parameter. This is particularly useful for creating variations of a sound without affecting the original instance. The cloned instance includes all properties, playback settings, and filters of the original, unless explicitly overridden.

    Parameters

    • overrides: Partial<SoundCloneOverrides> = {}

      An object specifying properties to override in the cloned instance. This can include audio settings like volume, playback rate, and spatial positioning, as well as more complex configurations like 3D audio options and filter adjustments.

    Returns Sound

    A new Sound instance that is a clone of the current sound.

  • Fades in all playbacks from silence to their current volume.

    Parameters

    • duration: number

      The fade duration in milliseconds.

    • Optional type: FadeType

      The fade curve type. Defaults to "linear".

    Returns Promise<void>

    Resolves when all fades complete.

  • Fades out all playbacks from their current volume to silence.

    Parameters

    • duration: number

      The fade duration in milliseconds.

    • Optional type: FadeType

      The fade curve type. Defaults to "linear".

    Returns Promise<void>

    Resolves when all fades complete.

  • Fades the volume of all playbacks to a target value over a duration.

    Parameters

    • value: number

      The target volume (0 to 1).

    • duration: number

      The fade duration in milliseconds.

    • Optional type: FadeType

      The fade curve type. Defaults to "linear".

    Returns Promise<void>

    Resolves when all fades complete.

  • Sets or retrieves the loop behavior for the sound. If loopCount is provided, the sound will loop the specified number of times. If loopCount is 'infinite', the sound will loop indefinitely until stopped. If no argument is provided, the method returns the current loop count setting.

    Parameters

    • Optional loopCount: LoopCount

      The number of times to loop or 'infinite' for indefinite looping.

    Returns LoopCount

    The current loop count setting if no argument is provided.

  • Remove event listener.

    Type Parameters

    Parameters

    • event: K
    • listener: ((data) => void)

    Returns void

  • Register event listener.

    Type Parameters

    Parameters

    • event: K
    • listener: ((data) => void)

    Returns (() => void)

    Cleanup function

      • (): void
      • Returns void

  • Generates a Playback instance for the sound without starting playback. This allows for pre-configuration of playback properties such as volume and position before the sound is actually played.

    Returns Playback[]

    An array of Playback instances that are ready to be played.

  • Removes a BiquadFilterNode from the container's filter chain. Only affects future playbacks - existing playbacks retain their cloned filters.

    Parameters

    Returns void

    Throws

    If the filter was never added to this container.

  • Parameters

    Returns void

  • Seeks to a specific time within the sound's playback.

    Parameters

    • time: number

      The time in seconds to seek to. This method iterates through all active Playback instances and calls their seek() method with the specified time.

    Returns void

  • Fades out all playbacks then stops them.

    Parameters

    • duration: number

      The fade-out duration in milliseconds.

    • Optional type: FadeType

      The fade curve type. Defaults to "linear".

    Returns Promise<void>

    Resolves when the fade completes and all playbacks are stopped.
