2005:Audio Key Finding Results

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.

Rank	Participant	Composite Percentage Score	Total Score		Percentage Score		Correct Keys		Perfect 5th Errors		Relative Major/Minor Errors		Parallel Major/Minor Errors		Other Errors		Runtime (s)		Machine
