soundstream 0.0.1

Implementation of SoundStream, an end-to-end neural audio codec

SoundStream - PyTorch

Implementation of SoundStream, an end-to-end neural audio codec

• 🔊 Implements SoundStream model inference
• 🎛️ Works with 27M parameter model pretrained on 10k hours of English speech (Multilingual LibriSpeech dataset)

Install

pip install soundstream

Usage

Note The pretrained model is configured as specified in NaturalSpeech 2, so it has different channels/strides than the original SoundStream.

import torchaudio

from soundstream import from_pretrained, load


waveform = load('in.wav')
audio_codec = from_pretrained()  # downloads model from Hugging Face

quantized = audio_codec(waveform, mode='encode')
recovered = audio_codec(quantized, mode='decode')

torchaudio.save('out.wav', recovered[0], 16000)
