README
# NeuralNote
NeuralNote is the audio plugin that brings **state-of-the-art Audio to MIDI conversion** into
your favorite Digital Audio Workstation.- Works with any tonal instrument (voice included)
- Supports polyphonic transcription
- Supports pitch bend detection
- Lightweight and very fast transcription
- Allows to adjust the parameters while listening to the transcription
- Allows to scale and time quantize transcribed MIDI directly in the plugin## Install NeuralNote
Download the latest release for your platform [here](https://github.com/DamRsn/NeuralNote/releases) (Windows and macOS (
Universal) supported)!Currently, only the raw `.vst3`, `.component` (Audio Unit), `.app` and `.exe` (Standalone) files are provided.
Installers will be created soon. In the meantime, you can manually copy the plugin/app file in the appropriate
directory. The code is signed on macOS, but not on Windows, so you might have to perform few extra steps in order to be
able to use NeuralNote on Windows.## Usage
![UI](NeuralNote_UI.png)
NeuralNote comes as a simple AudioFX plugin (VST3/AU/Standalone app) to be applied on the track to transcribe.
The workflow is very simple:
- Gather some audio
- Click record. Works when recording for real or when playing the track in a DAW.
- Or drop an audio file on the plugin. (.wav, .aiff, .flac, .mp3 and .ogg (vorbis) supported)
- The MIDI transcription instantly appears in the piano roll section.
- Listen to the result by clicking the play button.
- Play with the different settings to adjust the transcription, even while listening to it
- Individually adjust the level of the source audio and of the synthesized transcription
- Once you're satisfied, export the MIDI transcription with a simple drag and drop from the plugin to a MIDI track.**Watch our presentation video for the Neural Audio Plugin
competition [here](https://www.youtube.com/watch?v=6_MC0_aG_DQ)**.NeuralNote uses internally the model from Spotify's [basic-pitch](https://github.com/spotify/basic-pitch). See
their [blogpost](https://engineering.atspotify.com/2022/06/meet-basic-pitch/)
and [paper](https://arxiv.org/abs/2203.09893) for more information. In NeuralNote, basic-pitch is run
using [RTNeural](https://github.com/jatinchowdhury18/RTNeural) for the CNN part
and [ONNXRuntime](https://github.com/microsoft/onnxruntime) for the feature part (Constant-Q transform calculation +
Harmonic Stacking).
As part of this project, [we contributed to RTNeural](https://github.com/jatinchowdhury18/RTNeural/pull/89) to add 2D
convolution support.## Build from source
Requirements are: `git`, `cmake`, and your OS's preferred compiler suite.
Use this when cloning:
```
git clone --recurse-submodules --shallow-submodules https://github.com/DamRsn/NeuralNote
```The following OS-specific build scripts have to be executed at least once before being able to use the project as a
normal CMake project. The script downloads onnxruntime static library (that we created
with [ort-builder](https://github.com/olilarkin/ort-builder)) before calling CMake.#### macOS
```
$ ./build.sh
```#### Windows
Due to [a known issue](https://github.com/DamRsn/NeuralNote/issues/21), if you're not using Visual Studio 2022 (MSVC
version: 19.35.x, check `cl` output), then you'll need to manually build onnxruntime.lib like so:1. Ensure you have Python installed; if not, download at https://www.python.org/downloads/windows/ (this does not
currently work with Python 3.11, prefer Python 3.10).2. Execute each of the following lines in a command prompt:
```
git clone --depth 1 --recurse-submodules --shallow-submodules https://github.com/tiborvass/libonnxruntime-neuralnote ThirdParty\onnxruntime
cd ThirdParty\onnxruntime
python3 -m venv venv
.\venv\Scripts\activate.bat
pip install -r requirements.txt
.\convert-model-to-ort.bat model.onnx
.\build-win.bat model.required_operators_and_types.with_runtime_opt.config
copy model.with_runtime_opt.ort ..\..\Lib\ModelData\features_model.ort
cd ..\..
```Now you can get back to building NeuralNote as follows:
```
> .\build.bat
```#### IDEs
Once the build script has been executed at least once, you can load this project in your favorite IDE
(CLion/Visual Studio/VSCode/etc) and click 'build' for one of the targets.## Reuse code from NeuralNote’s transcription engine
All the code to perform the transcription is in `Lib/Model` and all the model weights are in `Lib/ModelData/`. Feel free
to use only this part of the code in your own project! We'll try to isolate it more from the rest of the repo in the
future and make it a library.The code to generate the files in `Lib/ModelData/` is not currently available as it required a lot of manual operations.
But here's a description of the process we followed to create those files:- `features_model.onnx` was generated by converting a keras model containing only the CQT + Harmonic Stacking part of
the full basic-pitch graph using `tf2onnx` (with manually added weights for batch normalization).
- the `.json` files containing the weights of the basic-pitch cnn were generated from the tensorflow-js model available
in the [basic-pitch-ts repository](https://github.com/spotify/basic-pitch-ts), then converted to onnx with `tf2onnx`.
Finally, the weights were gathered manually to `.npy` thanks to [Netron](https://netron.app/) and finally applied to a
split keras model created with [basic-pitch](https://github.com/spotify/basic-pitch) code.The original basic-pitch CNN was split in 4 sequential models wired together, so they can be run with RTNeural.
## Roadmap
- Improve stability
- Save plugin internal state properly, so it can be loaded back when reentering a session. Make parameters visible to
the DAW.
- Add tooltips
- Make internal synth support pitch bends
- Send MIDI out of the plugin to be routed to another instrument## Bug reports and feature requests
If you have any request/suggestion concerning the plugin or encounter a bug, please file a GitHub issue.
## Contributing
Contributions are most welcome! If you want to add some features to the plugin or simply improve the documentation,
please open a PR!## License

- [minimp3](https://github.com/lieff/minimp3) (CC0-1.0 license)## Could NeuralNote transcribe audio in real-time?
Unfortunately no and this for a few reasons:
- Basic Pitch uses the Constant-Q transform (CQT) as input feature. The CQT requires really long audio chunks (> 1s) to
get amplitudes for the lowest frequency bins. This makes the latency too high to have real-time transcription.
- The basic pitch CNN has an additional latency of approximately 120ms.
- The note events creation algorithm processes the posteriorgrams backward (from future to past) and is hence
non-causal.But if you have ideas please share!
