Bassline Pitch Prediction for Real-Time Performance Systems

This paper presents a methodology for predicting the pitch of bass notes by utilising their metrical position within the bar. Our system assumes two separate audio channels for drums and bass. We make use of onset detection and beat tracking algorithms to determine the onset times for each bass note and the beat locations. A monophonic bass track is analysed for repetitive structures relative to the beat grid, enabling the system to make a prediction of the pitch of each bass note prior to any pitch-related analysis. We present an analysis on a small collection of studio recordings.
