TorchAudio adds support for various audio-related datasets used in downstream tasks for benchmarking self-supervised learning models. With the addition of several new datasets, there is now support for the downstream tasks in version 1 of the SUPERB benchmark, which can be found in the s3prl repository.
For these datasets, we also add metadata support through a get_metadata function, enabling faster dataset iteration or preprocessing without the need to load waveforms. The function returns the same features as __getitem__, except it returns the relative waveform path rather than the loaded waveform.
