Free online AUP3 to OGG converter

A device, website, game, or media player may require Ogg Vorbis instead of an Audacity project file, or you may need a smaller file for sharing. Exporting the project creates a playable OGG file containing the rendered mix.

What the AUP3 format is

.aup3 is the native project format used by Audacity 3.0 and later. It is an SQLite-based project database containing audio data, tracks, labels, clip positions, edits, effect settings, and other information needed to reopen the project in Audacity.

An AUP3 file is not a conventional audio recording and cannot be opened by ordinary OGG players. It preserves an editable multitrack project; exporting it renders the audible result into one finished audio file. Open it in a current version of Audacity rather than changing the filename extension or using a converter that does not support Audacity projects.

What the OGG format is

OGG is a multimedia container. Audacity's OGG export normally uses the Vorbis lossy audio codec, which reduces file size substantially compared with uncompressed WAV. Ogg Vorbis is suitable for music, speech, podcasts, web distribution, and applications that explicitly support it.

OGG is not universally supported: compatibility is generally lower than MP3 or WAV on older hardware, consumer players, and some websites. The exported file contains a rendered mix, not separate tracks, editable effects, labels, or undo history.

How to convert AUP3 to OGG

1. Install and open a current version of Audacity.
2. Choose File → Open and select the .aup3 project.
3. Check the track contents, mute or solo tracks as needed, and confirm that the project plays correctly. Save the project first if you made changes.
4. Choose File → Export Audio.
5. Enter the output filename and destination, then select OGG Vorbis in the format list.
6. Choose the Vorbis quality setting. Higher quality produces a larger file; use a lower setting for speech or smaller downloads and a higher setting for music when file size permits.
7. Choose the export range if Audacity offers the choice between the entire project and the current selection, then select Export.
8. Enter metadata such as title, artist, or album if required, and confirm the export.

Audacity is the most reliable desktop tool because it directly understands the AUP3 project structure and renders its tracks and active effects. You can also use the free converter on 101convert.com without installing software; upload the project, select OGG as the output, download the result, and verify it in an Ogg Vorbis-compatible player. Uploading a project sends its embedded audio and project information to the service, so use the desktop method for sensitive material or projects that require exact Audacity compatibility.

Quality and compatibility limits

Vorbis encoding is lossy. If the project already uses compressed source audio, exporting to OGG adds another lossy encoding stage. Keep the AUP3 project for future editing and export a WAV master when you need an archival copy or expect to encode the audio again.

Audacity renders the tracks at the project's sample rate and channel configuration. Muted tracks, active effects, clipping, volume automation, and the selected export range all affect the OGG output. Listen to the exported file and check its duration before deleting the original project.

Renaming filename.aup3 to filename.ogg does not perform a conversion. The project must be opened and rendered by Audacity, 101convert.com, or another application that specifically supports the AUP3 format.
