[Invited Paper] Automated Cheering System Using Sound Communication for Live Performances

Year: 2025

Type: article

Abstract: We propose a customizable, automated cheering system that enhances fan experiences during live performances through sound-based communication in the audible band. The system operates in the 17–18.8 kHz frequency range, which is minimally perceived by the human ear. A chirp signal, known for its robustness against noise, is used to transmit index data and is additively embedded into the music. Receiver devices detect the chirp signal using correlation analysis, achieving synchronization with the performance. Based on the received 7-bit index data, the system automatically selects and displays the corresponding pre-configured idol cheering screen from a set of 128 messages in real-time.
