Audio Spike Detection on Gamelan using Envelope Shape Pattern Analysis
Abstract: Spike detection is
important for the analysis of gamelan signal processing, in detecting the
onset, transcription, and spikes occur on gamelan percussion instruments. Since
the current methods: absolute value and NEO, could not detect spikes properly,
we proposed to develop a new spike detection method. In this paper, the early
stage of spike detection in gamelan music audio was the determination of the
peak signal to obtain the form of a signal pattern (envelope like) which was
then used as threshold for determining the spike locations. We also
demonstrated the effectiveness of their method using shape pattern analysis to
detect spikes.
