Audio Datasets

Author: Moto Hira

torchaudio provides easy access to common, publicly accessible datasets. Please refer to the official documentation for the list of available datasets.

import IPython

import matplotlib.pyplot as plt


_SAMPLE_DIR = "_assets"
YESNO_DATASET_PATH = os.path.join(_SAMPLE_DIR, "yes_no")
os.makedirs(YESNO_DATASET_PATH, exist_ok=True)


def plot_specgram(waveform, sample_rate, title="Spectrogram"):
    waveform = waveform.numpy()

    figure, ax = plt.subplots()
    ax.specgram(waveform[0], Fs=sample_rate)
    figure.suptitle(title)
    figure.tight_layout()

Here, we show how to use the torchaudio.datasets.YESNO dataset.

dataset = torchaudio.datasets.YESNO(YESNO_DATASET_PATH, download=True)
