TorchAudio Ruby

🔥 An audio library for Torch.rb

Installation

First, install SoX. For Homebrew, use:

brew install sox

Add this line to your application’s Gemfile:

gem "torchaudio"

Getting Started

This library follows the Python API. Many methods and options are missing at the moment. PRs welcome!

Tutorial

• PyTorch tutorial
• Ruby code

Download the audio file and install the matplotlib gem first.

Basics

Load a file

waveform, sample_rate = TorchAudio.load("file.wav")

Save a file

TorchAudio.save("new.wave", waveform, sample_rate)

Transforms

TorchAudio::Transforms::Spectrogram.new.call(waveform)

Supported transforms are:

• AmplitudeToDB
• ComputeDeltas
• Fade
• MelScale
• MelSpectrogram
• MFCC
• MuLawDecoding
• MuLawEncoding
• Spectrogram
• Vol

Functional

TorchAudio::Functional.lowpass_biquad(waveform, sample_rate, cutoff_freq)

Supported functions are:

• amplitude_to_DB
• compute_deltas
• create_dct
• create_fb_matrix
• DB_to_amplitude
• dither
• gain
• highpass_biquad
• lowpass_biquad
• mu_law_decoding
• mu_law_encoding
• spectrogram

Datasets

Load a dataset

TorchAudio::Datasets::YESNO.new(".", download: true)

Supported datasets are:

• YESNO

Disclaimer

This library downloads and prepares public datasets. We don’t host any datasets. Be sure to adhere to the license for each dataset.
