cleanunet is a Python package that provides an easy-to-use interface for speech denoising, based on the official PyTorch implementation of CleanUNet. This package allows users to perform high-quality speech denoising with minimal setup, leveraging the power of CleanUNet directly from PyPI.

CleanUNet is a state-of-the-art model for causal speech denoising on raw waveforms, utilizing an encoder-decoder architecture with self-attention blocks. It was originally developed by Kong, Zhifeng; Ping, Wei; Dantrey, Ambrish; and Catanzaro, Bryan. Full details can be found in their paper: Speech Denoising in the Waveform Domain with Self-Attention.

To install cleanunet, simply use pip:

pip install cleanunet

cleanunet can be used to denoise audio files easily. Here's a basic example:

import torchaudio
from cleanunet import CleanUNet

# Load an audio file
aud, sr = torchaudio.load("path_to_your_audio_file.wav")

# Initialize CleanUNet
net = CleanUNet.from_pretrained(variant='full') # or 'high'

# Perform denoising
denoised_aud = net(aud)[0]

# Save the denoised audio
torchaudio.save('path_to_denoised_audio_file.wav', denoised_aud, sr)

To utilize CUDA for faster processing:

aud, sr = torchaudio.load("path_to_your_audio_file.wav")
net = CleanUNet.from_pretrained(variant='full', device='cuda')
denoised_aud = net(aud.to('cuda'))[0]

This package is a pip-installable version of the CleanUNet model, as described in the paper by Kong et al. The original implementation and more comprehensive details can be found in their GitHub repository.

The structure and distributed training are adapted from WaveGlow (PyTorch), and other components are adapted from various sources as detailed in the original CleanUNet repository.
