This dataset is preprocessed and compressed to 32khz mp3 files. The bytes of the mp3 files are embedded.
|
| 35 |
-
The mp3 bytes can be decoded quickly using for [example](https://github.com/kkoutini/PaSST/blob/4519e4605989b8c2e62dccb5b928af9bf7bf8602/audioset/dataset.py#L55) or [minimp3](https://github.com/f0k/minimp3py).
