torchaudio: an audio library for PyTorch

The aim of torchaudio is to apply PyTorch to
the audio domain. By supporting PyTorch, torchaudio follows the same philosophy
of providing strong GPU acceleration, having a focus on trainable features through
the autograd system, and having consistent style (tensor names and dimension names).
Therefore, it is primarily a machine learning library and not a general signal
processing library. The benefits of PyTorch can be seen in torchaudio through
having all the computations be through PyTorch operations which makes it easy
to use and feel like a natural extension.

Support audio I/O (Load files, Save files)

Load a variety of audio formats, such as wav, mp3, ogg, flac, opus, sphere, into a torch Tensor using SoX
Kaldi (ark/scp)

Dataloaders for common audio datasets
Common audio transforms

Spectrogram, AmplitudeToDB, MelScale, MelSpectrogram, MFCC, MuLawEncoding, MuLawDecoding, Resample

Compliance interfaces: Run code using PyTorch that align with other libraries

Kaldi: spectrogram, fbank, mfcc

Installation
Please refer to https://pytorch.org/audio/main/installation.html for installation and build process of TorchAudio.
Quick Usage
import torchaudio

waveform, sample_rate = torchaudio.load('foo.wav') # load tensor from file
torchaudio.save('foo_save.wav', waveform, sample_rate) # save tensor to file

Backend Dispatch
By default in OSX and Linux, torchaudio uses SoX as a backend to load and save files.
The backend can be changed to SoundFile
using the following. See SoundFile
for installation instructions.
import torchaudio
torchaudio.set_audio_backend("soundfile") # switch backend

waveform, sample_rate = torchaudio.load('foo.wav') # load tensor from file, as usual
torchaudio.save('foo_save.wav', waveform, sample_rate) # save tensor to file, as usual

Note

SoundFile currently does not support mp3.
"soundfile" backend is not supported by TorchScript.
