Abstract :
An onset detection system based on linear prediction with scalable complexity is proposed in this work. One unique feature of the proposed onset detection algorithm is that it can offer a trade-off between complexity and detection accuracy by adjusting its parameters. Consequently, it can be used in consumer electronics such as karaoke performance evaluation and automatic visual effect generation in portable media players.
