Extract text from Unreal Engine audio packages (UAX)
To convert UAX audio packages to another format, you need Unreal Engine or other Game software.
To convert other file formats to the "Unreal Audio Package" file type, you need software like Unreal Engine or a similar tool.
.UAX files are proprietary audio packages used by the Unreal Engine to store and manage game sound effects, music, and voice assets. They serve as bulk containers, allowing a game client to load hundreds of related sounds simultaneously rather than fetching individual audio files from a hard drive.
Game developers and modders typically open and edit .UAX files using the native Unreal Editor toolset included with the engine. For extraction, third-party reverse-engineering tools like UE Viewer are popular among the modding community, especially for older titles like Lineage II.
You cannot play a .UAX file directly in standard media players like VLC or Windows Media Player. The format acts as a compressed archive rather than a standard audio stream. This creates a major challenge for gamers who want to extract the soundtrack or sound effects from their favorite games. The proprietary nature of the container means that without dedicated modding tools, the audio remains completely locked away and unusable in standard workflows.
To make the audio usable, users must extract the internal contents and convert them to universal formats like WAV, MP3, or OGG. Converting to WAV preserves the exact original quality of the uncompressed game files, while converting to MP3 introduces slight compression but guarantees playback compatibility with virtually any device.
This file format is exceptionally difficult to open or convert because it is a closed, engine-specific container. Often, only the original game software or highly specific community-built extraction tools can properly read or export the embedded audio data. Standard online converters will completely fail to process it. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your UAX file, detects the exact format, and lets you read the text inside.
Users also converted RUT_UAX, USA_UAX, UMX, WAV, MP3, OGG, EXE, SPL7, FCSTD, F3D, WEBARCHIVE, CDW and DAT files.
If you want to convert UAX file to MP3, WAV, AAC, FLAC, OGG, WMA, M4A, AIFF, OPUS, ALAC, APE or WV, you can use Unreal Engine or similar software from the "Game Audio Asset Archive" category. In the File menu, look for Save As… or Export….
To convert MIDI, AAC, TTA, AU, WV, DTS, MID, FLAC, RA, MP3, PCM or WAV files to UAX, try Unreal Engine or another comparable tool in the "Game Audio Asset Archive" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our UAX converter.
