### Sample WAV Processing Pipeline

Source: https://hexdocs.pm/membrane_wav_plugin

Example of a Membrane pipeline that reads a WAV file, parses it, converts the audio format, serializes it back to WAV, and saves it to a new file.

```elixir
defmodule Mixing.Pipeline do
  use Membrane.Pipeline

  @impl true
  def handle_init(_ctx, _opts) do
    spec = child(:file_src, %Membrane.File.Source{location: "/tmp/input.wav"})
      |> child(:parser, Membrane.WAV.Parser)
      |> child(:converter, %Membrane.FFmpeg.SWResample.Converter{
        input_stream_format: %Membrane.RawAudio{channels: 1, sample_rate: 16_000, sample_format: :s16le},
        output_stream_format: %Membrane.RawAudio{channels: 2, sample_rate: 48_000, sample_format: :s16le}
      })
      |> child(:serializer, Membrane.WAV.Serializer)
      |> child(:file_sink, %Membrane.File.Sink{location: "/tmp/output.wav"})

    {[spec: spec], %{}}
  end
end
```
