Extract text from ULT files
To convert your ULT file to another format, you need Ultimaker Cura or other Audio software.
To convert other file formats to the "Tracker Module" file type, you need software like Ultimaker Cura or a similar tool.
The .ULT file extension represents two completely different formats, creating a common source of confusion. Most frequently today, it is a Sliced 3D Model created by Ultimaker Cura for older Ultimaker 3D printers. These files contain G-code instructions (toolpaths, temperatures, speeds) rather than editable 3D geometry. Users often try to open them in CAD software like Fusion 360 or Blender, only to find they are unrecognized or import as non-editable path lines. For these files, the goal is often to visualize the print path or, rarely, to reverse-engineer a printable mesh.
Alternatively, a .ULT file is an Ultra Tracker Module, an audio format from the 1990s designed for the Gravis Ultrasound sound card. Unlike standard MP3 or WAV files, these modules contain raw instrument samples and sequencing patterns. They provide high-quality playback for their size but are completely incompatible with modern media players like iTunes or standard web browsers. To make the music accessible, users must convert them to MP3 or FLAC, or use specialized tracker software.
Convert.Guru analyzes your ULT file, detects the exact format, and lets you read the text inside.
If you want to convert ULT file to MP3, WAV, AAC, FLAC, OGG, WMA, M4A, AIFF, OPUS, ALAC, APE or WV, you can use Ultimaker Cura or similar software from the "3D Printing Instructions / Audio Module" category. In the File menu, look for Save As… or Export….

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 ULT converter.
