About ON files
The .on file extension is primarily classified as an Audio Utility Tuningwrench Compressed File. It is a highly proprietary, legacy archive format used to store and compress audio data. Because the original software developer is unknown and the software is virtually extinct, these files are notoriously difficult to open today. Most modern media players and standard online converters cannot process the proprietary compression algorithm used in .ON files. This means that without the original Tuningwrench software, extracting the audio into a MP3 or WAV is impossible through conventional means. Furthermore, many users encounter .ON files simply because of a typo - someone accidentally truncated a Microsoft OneNoteONE file extension. If you are stuck with a .on file, standard online converters will fail. If our analysis detects a supported underlying or embedded format - such as a standard ZIP directory or an embedded audio stream - viewing or conversion may still be possible.
Convert.Guru analyzes your ON file, detects the exact format, and lets you read the text inside.
If you want to convert ON file to PDF, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT or DB, you can use Audio Utility Tuningwrench or similar software from the "Legacy Audio Archive" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to ON, try Audio Utility Tuningwrench or another comparable tool in the "Legacy Audio Archive" category.
The ON Converter Story
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 ON converter.
