Extract text from UTAU sequences (UST)
To convert UST sequences to another format, you need UTAU or other Audio software.
To convert other file formats to the "Vocal Synth Sequence File" file type, you need software like UTAU or a similar tool.
.ust files are UTAU Sequence Text files utilized by the UTAU singing synthesizer. They function as a musical score, storing data such as notes, lyrics, phonemes, tempo, and precise pitch-bend parameters.
The primary disadvantage of the .ust format is its strict proprietary nature. It is not an audio file; you cannot play it in VLC media player or Windows Media Player. It only contains text-based instructions for the synthesizer. To hear the song, you must have the exact voicebank installed, otherwise the file will produce absolute silence. Furthermore, the internal phonetic mapping is highly specific, often requiring manual conversion between Hiragana and Romaji aliases if you change voicebanks.
To use the melody in a standard Digital Audio Workstation (DAW) like FL Studio, you must convert it to a Standard MIDI file (MID). Note that MIDI conversion will strip out all lyrics and UTAU-specific vocal expressions. If you are migrating the project to Yamaha Vocaloid, convert the file to VSQX to preserve the lyrics and basic note timing.

If you want to convert UST file to EST, PST, IST, VSQX, CST, MP3, WAV, AAC, FLAC, OGG, WMA or M4A, you can use UTAU or similar software from the "Vocal synthesizer sequence storage" 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 UST, try UTAU or another comparable tool in the "Vocal synthesizer sequence storage" 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 UST converter.
