Std.Audio.Device

17 public declarations

• closeStream&Std.Audio.Device.Stream -> Bool -> Int -> Result[(), Std.Audio.Device.DeviceError]

  Release the stream exactly once, optionally sounding every queued frame.

  fn
• DeviceError

  Why a bounded clip could not be presented to the default output device.

  type
• openStream&Std.Audio.Device.StreamPlan -> Result[Std.Audio.Device.Stream, Std.Audio.Device.DeviceError]

  Open the default output and return the format accepted by its queue.

  fn
• pause&Std.Audio.Device.Stream -> Result[(), Std.Audio.Device.DeviceError]

  Stop consuming queued frames while keeping them and the stream's position.

  fn
• planInt -> Int -> Int -> Result[Std.Audio.Device.Plan, Std.Audio.Device.DeviceError]

  Admit two to eight preallocated buffers of 16 through 4,096 frames each.

  fn
• Plan

  Queue bounds and the total monotonic deadline for one clip.

  type
• play&Std.Audio.Device.Plan -> &Std.Audio.Pcm -> Result[Std.Audio.Device.Playback, Std.Audio.Device.DeviceError]

  Play one admitted interleaved signed-16 clip and await exact completion.

  fn
• Playback

  Completion reported by the native device queue.

  type
• resume&Std.Audio.Device.Stream -> Result[(), Std.Audio.Device.DeviceError]

  Continue consuming queued frames from where a pause left them.

  fn
• setVolume&Std.Audio.Device.Stream -> Float64 -> Result[(), Std.Audio.Device.DeviceError]

  Set linear output volume from silence through unity.

  fn
• snapshot&Std.Audio.Device.Stream -> Result[Std.Audio.Device.StreamSnapshot, Std.Audio.Device.DeviceError]

  Read one coherent telemetry sample and audio-master clock.

  fn
• Stream

  One evaluation-owned output capability and its negotiated format.

  type
• streamPlanStd.Audio.Format -> Int -> Int -> Int -> Result[Std.Audio.Device.StreamPlan, Std.Audio.Device.DeviceError]

  Admit a persistent stream request before touching a device.

  fn
• StreamPlan

  Bounds and requested PCM shape for a persistent output stream.

  type
• StreamSnapshot

  Monotonic counters and the audio-master media clock.

  type
• StreamState

  Observable output state without exposing a target framework.

  type
• write&Std.Audio.Device.Stream -> &Std.Audio.Pcm -> Result[Int, Std.Audio.Device.DeviceError]

  Enqueue one exact PCM chunk with bounded backpressure.
