### Install Membrane MP3 MAD Plugin (Elixir)

Source: https://hexdocs.pm/membrane_mp3_mad_plugin/index

Add the Membrane MP3 MAD plugin dependency to your `mix.exs` file. After adding the line, run `mix deps.get` to fetch the dependency. This package relies on the MAD library, which is typically installed automatically.

```elixir
{:membrane_mp3_mad_plugin, "~> 0.18.4"}
```

### Sample MP3 Decoding Pipeline (Elixir)

Source: https://hexdocs.pm/membrane_mp3_mad_plugin/index

Demonstrates how to create a Membrane pipeline to read an MP3 file, decode it using the MAD decoder, and save the raw audio payload to a file. This example defines a pipeline with a File source, MAD decoder, and File sink.

```elixir
defmodule MadExamplePipeline do
  use Membrane.Pipeline

  alias Membrane.MP3.MAD
  alias Membrane.File

  @impl true
  def handle_init(_ctx, _opts) do
    structure =
      child(:src, %File.Source{location: "input.mp3"})
      |> child(:decoder, MAD.Decoder)
      |> child(:sink, %File.Sink{location: "output.raw"})

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

### Sample MP3 Decoding Pipeline using Membrane MP3 MAD Plugin

Source: https://hexdocs.pm/membrane_mp3_mad_plugin/readme

This Elixir code defines a sample pipeline using the Membrane Multimedia Framework and the MP3 MAD plugin. It sets up a pipeline that reads an MP3 file ('input.mp3'), decodes it using `Membrane.MP3.MAD.Decoder`, and saves the raw decoded payload to 'output.raw'.

```elixir
defmodule MadExamplePipeline do
  use Membrane.Pipeline

  alias Membrane.MP3.MAD
  alias Membrane.File

  @impl true
  def handle_init(_ctx, _opts) do
    structure =
      child(:src, %File.Source{location: "input.mp3"})
      |> child(:decoder, MAD.Decoder)
      |> child(:sink, %File.Sink{location: "output.raw"})

    {[spec: structure], %{}}
  end
end
copy

```

### Add Membrane MP3 MAD Plugin Dependency in mix.exs

Source: https://hexdocs.pm/membrane_mp3_mad_plugin/readme

This snippet shows how to add the Membrane MP3 MAD plugin to your project's dependencies in the `mix.exs` file. After adding the line, you should run `mix deps.get` to fetch the package. This plugin requires the MAD library, which is usually linked automatically.

```elixir
        {:membrane_mp3_mad_plugin, "~> 0.18.4"}copy

```
