# Audio file compatibility

> Information about the audio file formats Unity supports.

Unity supports various audio file formats and you can import and use these files as [Audio Clips](/engine/6000.6/manual/class-audio-clips.md).

This page gives an overview about the audio file formats Unity supports. For instructions on how to import an audio file, refer to [Import audio files into Unity](/engine/6000.6/manual/audio/files/import.md).

For information about how Unity encodes your files once they are imported, refer to [Audio file compression in Unity](/engine/6000.6/manual/audio/files/compression.md).

## Supported audio file formats

Unity supports mono, stereo, and multichannel audio assets up to eight channels.

You can import the following audio file formats into Unity:

| **Format**                       | **Extensions** |
| -------------------------------- | -------------- |
| MPEG layer 3                     | .mp3           |
| Audio Interchange File Format    | .aiff / .aif   |
| Microsoft Wave                   | .wav           |
| Ogg Vorbis                       | .ogg           |
| Free Lossless Audio Codec (FLAC) | .flac          |

Unity also lets you import [tracker modules](/engine/6000.6/manual/audio/tracker-modules.md) in the following formats:

| **Format**                   | **Extensions** |
| ---------------------------- | -------------- |
| Ultimate Soundtracker module | .mod           |
| FastTracker 2 module         | .xm            |
| Impulse Tracker module       | .it            |
| Scream Tracker module        | .s3m           |

The tracker module assets behave the same way as any other audio assets in Unity although no waveform preview is available in the asset import inspector.
