Introduction
Goal
To classify polyphonic music audio (in PCM format) into genre categories.
Dataset
Two sets of data were used: Magnatune and USPOP. The Magnatune dataset has a hierarchical genre taxonomy, while the USPOP categories are at a single level. The audio sampling rates used were either 44.1 KHz or 22.05 KHz (mono). More data information is in the following table:
| Dataset | Size (@ 44.1 KHz) | Number of Training Files | Number of Testing Files |
|---|---|---|---|
| Magnatune | 34.3 GB | 1005 | 510 |
| USPOP | 28.4 GB | 940 | 474 |
