Extract text from Omnisphere part presets (PRT_OMN)
To convert PRT_OMN part presets to another format, you need Omnisphere or other Settings software.
To convert other file formats to the "Audio Plugin Preset" file type, you need software like Omnisphere or a similar tool.
The .prt_omn file is a proprietary synthesizer part preset used exclusively by Spectrasonics Omnisphere, a flagship software instrument. These files store parameters like oscillator choices, envelope settings, filter routing, and effects chains for a specific part within a multi-timbral setup.
Opening this file natively requires an expensive software license for Omnisphere, which is a major disadvantage for producers trying to share sounds with collaborators who do not own the plugin. Furthermore, the format is entirely proprietary and locked into the Spectrasonics ecosystem.
Many users mistakenly try to convert .prt_omn files directly to audio formats like WAV or MP3. This is impossible because the file contains zero audio data; it is merely a text-based recipe instructing the synthesizer on how to generate sound. Standard online audio converters fail completely when processing these files because they look for waveform data that does not exist.
Underneath the proprietary extension, the file is actually structured as standard XML. The most pragmatic conversion target is XML or TXT, allowing you to read the raw synthesis parameter values. Because this is a closed, proprietary format, it is extremely difficult to translate patches into generic plugin formats like FXP or VSTPRESET. Often, only the original software can properly read or export the sound data. However, just drag and drop your file onto convert.guru to see what it is and convert it if supported. Since our analysis detects the supported underlying XML format, viewing the text content or converting it to generic readable text is fully supported.
Convert.Guru analyzes your PRT_OMN file, detects the exact format, and lets you read the text inside.
Users also converted FFX, NFX and EPR files.
If you want to convert PRT_OMN file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Omnisphere or similar software from the "Synthesizer Part Preset" 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 PRT_OMN, try Omnisphere or another comparable tool in the "Synthesizer Part Preset" 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 PRT_OMN converter.
