# 音频工具

**音频编码器推荐全都加入系统的PATH路径中，这样会大大便利我们使用CLI调用这些软件**

## AAC编码器

AAC编码器这里就推荐QAAC，QAAC是苹果AAC编码器的一个封装前端，所以使用QAAC就必须安装一个64位的iTunes。由于在AAC上苹果编码器做的最好，虽然麻烦但是还是用它好了。

QAAC安装指引：<https://github.com/nu774/qaac/wiki/Installation>

QAAC CLI参考：<https://github.com/nu774/qaac/wiki/Command-Line-Options>

你可以在这里下载到QAAC：<https://github.com/nu774/qaac/releases>

iTunes怎么下我就懒得写了

## FLAC编码器

如果需要无损音频编码器，那么FLAC准没错了。

你可以在这里下载到它：<https://ftp.osuosl.org/pub/xiph/releases/flac/>
