# Membrane MP3 Lame plugin

[![Hex.pm](https://img.shields.io/hexpm/v/membrane_mp3_lame_plugin.svg)](https://hex.pm/package/membrane_mp3_lame_plugin)

[![CircleCI](https://circleci.com/gh/membraneframework/membrane_mp3_lame_plugin.svg?style=svg)](https://circleci.com/gh/membraneframework/membrane_mp3_lame_plugin)

The module contains element that encodes raw audio to MPEG-1 layer 3 format.

For now, only encoding audio with 2 channels, s32le format and 44100 sample rate is supported.

It is a part of [Membrane Multimedia Framework](https://membraneframework.org).

## Installation

Add the following line to your `deps` in `mix.exs`. Then, run `mix deps.get`.

```elixir

    {:membrane_mp3_lame_plugin, "~> 0.18.5"}

```

This package depends on the [Lame encoder library](http://lame.sourceforge.net) library. The precompiled builds will be pulled and linked automatically. However, should there be any problems, consider installing it manually.

### MacOS

```bash

brew install lame

```

### Ubuntu

```bash

sudo apt-get install libmp3lame-dev

```

### Arch, Manjaro

```bash

sudo pacman -S lame

```

### Fedora

```bash

sudo dnf install lame-devel

```

## Usage

You can find an example in [`example.exs`](example.exs), where the `MP3.Lame.Encoder` element

was used in a pipeline that redirects audio from default input to an MP3 file.

To run the example, you can use the following command:

```bash

iex example.exs

```
