2010 talk:Audio Key Detection

From MIREX Wiki

A potential discussion about Audio Key Detection could be about the nature of the database, which is not "real" audio. I believe the keys of the Beatles songs are available, and could thus be used in this task.

Another discussion could be about the key changes. Instead of "only" providing the global key (or main key) of a song, the proposed algorithms could follow the different keys as they may change during the song. If this is not the main goal of this task, maybe another task, labelled Audio Key Changes could be considered in the future.
