Sound synthesised on the BEAM: play a TuningFork.Voice on a TuningFork.Stage.
{:ok, _pid} = TuningFork.Stage.start_link(sink: TuningFork.Sink.Speaker)
TuningFork.play(TuningFork.Voice.new(shape: :sine, freq: 440.0))Summary
Functions
Whether this machine can play sound.
Sound a voice on the stage registered as TuningFork.Stage.
Render a voice to signed 16-bit little-endian PCM without playing it.
Start a stage under tuning_fork's own DynamicSupervisor.
Functions
@spec available?() :: boolean()
Whether this machine can play sound.
Asked of TuningFork.Sink.Speaker, and false when the tuning_fork_speaker package is
not installed.
@spec play(TuningFork.Voice.t()) :: :ok
Sound a voice on the stage registered as TuningFork.Stage.
Returns immediately; the voice is rendered inside the stage.
@spec render(TuningFork.Voice.t(), pos_integer(), pos_integer()) :: binary()
Render a voice to signed 16-bit little-endian PCM without playing it.
rate is samples per second and channels is 1 for mono or 2 for stereo. Stereo applies
the voice's :pan.
@spec start_stage(keyword()) :: DynamicSupervisor.on_start_child()
Start a stage under tuning_fork's own DynamicSupervisor.
opts are TuningFork.Stage.start_link/1's options. The stage is not linked to the
caller.
