# `TuningFork.Sink.Process`
[🔗](https://github.com/jaman/tuning_fork/blob/v0.1.11/tuning_fork/lib/tuning_fork/sink/process.ex#L1)

Raw signed 16-bit little-endian PCM as messages to a process, paced to real time: each
chunk arrives as `{:pcm, chunk}`, and the sink sleeps until the audio before it has
nearly played out, keeping `:lead_ms` in flight.

    TuningFork.Stage.start_link(sink: TuningFork.Sink.Process, sink_opts: [owner: self()])

A write after the owner has exited returns `{:error, :owner_gone}`, which stops the
stage feeding the sink.

## Options

  * `:owner` — the process the chunks go to. Required
  * `:lead_ms` — audio kept in flight ahead of real time. Default `60`
  * `:rate`, `:channels` — the PCM format, as the stage passes them
