Goal: The evaluation of key finding algorithms applied to audio sound files
Dataset: 1,252 audio files synthesized from MIDI Note: There is a close relationship (same musical datasets) between this contest and the Symbolic Key Finding contest. Here is a link to the Symbolic Key Finding results.
Two databases used: Winamp synthesized audio (w) and Timidity with Fusion soundfonts synthesized audio (t). Each database is approximately 3.1 gigabytes for a total of 6.2 gigabytes of audio files.
The composite score is calculated by averaging the Winamp and
Timidity scores.
