This repository is the official implementation of [Neural Waveshaping Synthesis](https://benhayes.net/projects/nws/).

## Model Architecture



## Requirements

To install:

```setup

pip install -r requirements.txt

pip install -e .

```

We recommend installing in a virtual environment.

## Data

We trained our checkpoints on the [URMP](http://www2.ece.rochester.edu/projects/air/projects/URMP.html) dataset.

Once downloaded, the dataset can be preprocessed using `scripts/create_urmp_dataset.py`. 

This will consolidate recordings of each instrument within the dataset and preprocess them according to the pipeline in the paper.

```bash

python scripts/create_urmp_dataset.py \

  --gin-file gin/data/urmp_4second_crepe.gin \ 

  --data-directory /path/to/urmp \

  --output-directory /path/to/output \

  --device cuda:0  # torch device string for CREPE model

```

Alternatively, you can supply your own dataset and use the general `create_dataset.py` script:

```bash

python scripts/create_dataset.py \

  --gin-file gin/data/urmp_4second_crepe.gin \ 

  --data-directory /path/to/dataset \

  --output-directory /path/to/output \

  --device cuda:0  # torch device string for CREPE model

```

## Training

To train a model on the URMP dataset, use this command:

```bash

python scripts/train.py \

  --gin-file gin/train/train_newt.gin \

  --dataset-path /path/to/processed/urmp \

  --urmp \

  --instrument vn \  # select URMP instrument with abbreviated string

  --load-data-to-memory

```

Or to use a non-URMP dataset:

```bash

python scripts/train.py \

  --gin-file gin/train/train_newt.gin \

  --dataset-path /path/to/processed/data \

  --load-data-to-memory

```
