3G2 is a multimedia container format used mainly for mobile video and audio, originally associated with 3G phones. AU is an audio file format developed by Sun Microsystems, commonly used for simple sound clips and legacy Unix systems. Converting 3G2 to AU means extracting the audio stream from a video container and saving it as an AU audio file.
Why convert 3g2 to au
You may want this conversion when you only need the sound from a 3G2 video, need a lightweight legacy audio format, or must work with software that supports AU better than modern video containers.
Best software for conversion
FFmpeg is the best overall choice for 3G2 to AU conversion because it is fast, free, supports many formats, and preserves audio quality well. For a graphical option, VLC media player can also convert media files, though it is less flexible than FFmpeg.
How to convert with ffmpeg
Use FFmpeg from the command line to extract audio and save it as AU:
ffmpeg -i input.3g2 output.au
If you want to control audio settings, you can specify codec and bitrate depending on the source audio and compatibility needs.
How to convert with vlc
In VLC, open the file and use the conversion feature:
Media → Convert / Save → Add → Convert / Save
Then choose an audio profile that supports AU output, if available, or use a compatible export option through additional settings.
Important notes
- AU is an older format, so compatibility may be limited in modern players.
- 3G2 files may contain video and audio; the conversion usually keeps only the audio track.
- If the source has multiple audio tracks, make sure to select the correct one before converting.
- For best results, verify the output in an audio player that supports AU.
Recommended workflow
- Open the 3G2 file in FFmpeg or VLC.
- Extract or convert the audio stream.
- Save the result as .au.
- Test playback to confirm the file is valid.
Summary
3G2 to AU conversion is mainly an audio extraction task. FFmpeg is the most reliable converter, while VLC is a convenient alternative for users who prefer a graphical interface.
