🔥 An audio library for Torch.rb

Add this line to your application’s Gemfile:

gem "torchaudio"

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

Load a file (requires torchcodec)

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

Save a file (requires torchcodec)

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

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

Supported transforms are:

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

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
