⚠️ This project is still under development!
UltraSinger is a tool to automatically create UltraStar.txt, midi and notes from music. It automatically pitches UltraStar files, adding text and tapping to UltraStar files and creates separate UltraStar karaoke files. It also can re-pitch current UltraStar files and calculates the possible in-game score.
Multiple AI models are used to extract text from the voice and to determine the pitch.
Please mention UltraSinger in your UltraStar.txt file if you use it. It helps others find this tool, and it helps this tool get improved and maintained. You should only use it on Creative Commons licensed songs.
There are many ways to support this project. Starring ⭐️ the repo is just one 🙏
You can also support this work on GitHub sponsors or Patreon or Buy Me a Coffee.
This will help me a lot to keep this project alive and improve it.
- Install Python 3.10 (older and newer versions has some breaking changes). Download
- Also install ffmpeg separately with PATH. Download
- Go to folder
installand run install script for your OS.- Choose
GPUif you have an nvidia CUDA GPU. - Choose
CPUif you don't have an nvidia CUDA GPU.
- Choose
- In root folder just run
run_on_windows.batorrun_on_linux.shto start the app. - Now you can use the UltraSinger source code with
py UltraSinger.py [opt] [mode] [transcription] [pitcher] [extra]. See How to use for more information.

For standard use, you only need to use [opt]. All other options are optional.
-i "input/music.mp3"
-i https://www.youtube.com/watch?v=BaW_jenozKc
Note that if you run into a yt-dlp error such as Sign in to confirm you’re not a bot. This helps protect our community (yt-dlp issue) you can follow these steps:
- generate a cookies.txt file with yt-dlp
yt-dlp --cookies cookies.txt --cookies-from-browser firefox - then pass the cookies.txt to UltraSinger
--cookiefile cookies.txt
This re-pitch the audio and creates a new txt file.
-i "input/ultrastar.txt"
Keep in mind that while a larger model is more accurate, it also takes longer to transcribe.
For the first test run, use the tiny, to be accurate use the large-v2 model.
-i XYZ --whisper large-v2
Currently provided default language models are en, fr, de, es, it, ja, zh, nl, uk, pt.
If the language is not in this list, you need to find a phoneme-based ASR model from
🤗 huggingface model hub. It will download automatically.
Example for romanian:
-i XYZ --whisper_align_model "gigant/romanian-wav2vec2"
Is on by default. Can also be deactivated if hyphenation does not produce anything useful. Note that the word is simply split, without paying attention to whether the separated word really starts at the place or is heard.
-i XYZ --hyphenation True
Pitching is done with the crepe model.
Also consider that a bigger model is more accurate, but also takes longer to pitch.
For just testing you should use tiny.
If you want solid accurate, then use the full model.
-i XYZ --crepe full
The vocals are separated from the audio before they are passed to the models. If problems occur with this, you have the option to disable this function; in which case the original audio file is used instead.
-i XYZ --disable_separation True
For Sheet Music generation you need to have MuseScore installed on your system.
Or provide the path to the MuseScore executable.
-i XYZ --musescore_path "C:/Program Files/MuseScore 4/bin/MuseScore4.exe"
This defines the format version of the UltraStar.txt file. For more info see Official UltraStar format specification.
You can choose between 3 different format versions. The default is 1.0.0.
0.3.0is the old format version. Use this if you have problems with the new format.1.0.0is the current format version.1.1.0is the upcoming format version. It is not finished yet.
-i XYZ --format_version 1.0.0
The score that the singer in the audio would receive will be measured. You get 2 scores, simple and accurate. You wonder where the difference is? Ultrastar is not interested in pitch hights. As long as it is in the pitch range A-G you get one point. This makes sense for the game, because otherwise men don't get points for high female voices and women don't get points for low male voices. Accurate is the real tone specified in the txt. I had txt files where the pitch was in a range not singable by humans, but you could still reach the 10k points in the game. The accuracy is important here, because from this MIDI and sheet are created. And you also want to have accurate files
With a GPU you can speed up the process. Also the quality of the transcription and pitching is better.
You need a cuda device for this to work. Sorry, there is no cuda device for macOS.
It is optional (but recommended) to install the cuda driver for your gpu: see driver.
Install torch with cuda separately in your venv. See tourch+cuda.
Also check you GPU cuda support. See cuda support
Command for pip:
pip3 install torch==2.0.1+cu117 torchvision==0.15.2+cu117 torchaudio==2.0.2+cu117 --index-url https://download.pytorch.org/whl/cu117
When you want to use conda instead you need a different installation command.
The pitch tracker used by UltraSinger (crepe) uses TensorFlow as its backend. TensorFlow dropped GPU support for Windows for versions >2.10 as you can see in this release note and their installation instructions.
For now UltraSinger runs the latest version available that still supports GPUs on windows.
For running later versions of TensorFlow on windows while still taking advantage of GPU support the suggested solution is to run UltraSinger in a container.
If something crashes because of low VRAM then use a smaller model.
Whisper needs more than 8GB VRAM in the large model!
You can also force cpu usage with the extra option --force_cpu.
