# DiffWave
 [](https://github.com/lmnt-com/diffwave/blob/master/LICENSE)
DiffWave is a fast, high-quality neural vocoder and waveform synthesizer. It starts with Gaussian noise and converts it into speech via iterative refinement. The speech can be controlled by providing a conditioning signal (e.g. log-scaled Mel spectrogram). The model and architecture details are described in [DiffWave: A Versatile Diffusion Model for Audio Synthesis](https://arxiv.org/pdf/2009.09761.pdf).
## What's new (2021-04-01)
- fast sampling algorithm based on v3 of the DiffWave paper
## What's new (2020-10-14)
- new pretrained model trained for 1M steps
- updated audio samples with output from new model
## Status (2021-04-01)
- [x] fast inference procedure
- [x] stable training
- [x] high-quality synthesis
- [x] mixed-precision training
- [x] multi-GPU training
- [x] command-line inference

## Audio samples
[22.05 kHz audio samples](https://lmnt.com/assets/diffwave)
## Pretrained models
[22.05 kHz pretrained model](https://lmnt.com/assets/diffwave/diffwave-ljspeech-22kHz-1000578.pt) (31 MB, SHA256: `d415d2117bb0bba3999afabdd67ed11d9e43400af26193a451d112e2560821a8`)
This pre-trained model is able to synthesize speech with a real-time factor of 0.87 (smaller is faster).
### Pre-trained model details
- trained on 4x 1080Ti
- default parameters
- single precision floating point (FP32)
- trained on LJSpeech dataset excluding LJ001* and LJ002*
- trained for 1000578 steps (1273 epochs)
## Install
Install using pip:
```
pip install diffwave
```
or from GitHub:
```
git clone https://github.com/lmnt-com/diffwave.git
cd diffwave
pip install .
```
### Training
Before you start training, you'll need to prepare a training dataset. The dataset can have any directory structure as long as the contained .wav files are 16-bit mono (e.g. [LJSpeech](https://keithito.com/LJ-Speech-Dataset/), [VCTK](https://pytorch.org/audio/_modules/torchaudio/datasets/vctk.html)). By default, this implementation assumes a sample rate of 22.05 kHz. If you need to change this value, edit [params.py](https://github.com/lmnt-com/diffwave/blob/master/src/diffwave/params.py).
```
python -m diffwave.preprocess /path/to/dir/containing/wavs
python -m diffwave /path/to/model/dir /path/to/dir/containing/wavs
# in another shell to monitor training progress:
tensorboard --logdir /path/to/model/dir --bind_all
```
You should expect to hear intelligible (but noisy) speech by ~8k steps (~1.5h on a 2080 Ti).
#### Multi-GPU training
By default, this implementation uses as many GPUs in parallel as returned by [`torch.cuda.device_count()`](https://pytorch.org/docs/stable/cuda.html#torch.cuda.device_count). You can specify which GPUs to use by setting the [`CUDA_DEVICES_AVAILABLE`](https://developer.nvidia.com/blog/cuda-pro-tip-control-gpu-visibility-cuda_visible_devices/) environment variable before running the training module.
### Inference API
Basic usage:
```python
from diffwave.inference import predict as diffwave_predict
model_dir = '/path/to/model/dir'
spectrogram = # get your hands on a spectrogram in [N,C,W] format
audio, sample_rate = diffwave_predict(spectrogram, model_dir, fast_sampling=True)
# audio is a GPU tensor in [N,T] format.
```
### Inference CLI
```
python -m diffwave.inference --fast /path/to/model /path/to/spectrogram -o output.wav
```
