Real-time Visualizer for Beats and Scratches of Breaking DJ Performances

Breaking is a dance duel between two dancers to music improvised by a DJ. Since breaking was chosen as an official competition at the Paris Olympics, many people have begun to watch the competitions on television. When a dancer freezes in time with a beat or scratch in breaking, it is called "kill the beat," and when it is successful, the audience gets very excited. However, TV viewers may have difficulty hearing the music due to the announcer's or commentator's voice, making it difficult to judge if the kill the beat is successful or not. In addition, some in the audience may be hard of hearing. Therefore, we developed a visualizer for the beats and scratches of breaking DJ performances.
