A PSYCHOACOUSTICS BASED SOUND ONSET DETECTION ALGORITHM FOR POLYPHONIC AUDIO

摘要：

We propose a new sound onset detection method using principles of psychoacoustics.Our algorithm mimics the human auditory system to detect onsets in polyphonic audio.A filterbank based processing scheme is used that allows for a more robust detection of onsets using a popular model of loudness.We show the versatility of our algorithm by evaluating its performance over a wide range of sounds.
