Design of an Automatic Beat-Matching Algorithm for Portable Media Devices

Methods to achieve accurate beat detection for musical signals have received much attention recently; however, very little literature has addressed techniques for achieving beat matching between two streams on portable devices with limited memory and processing power. This paper describes the architecture, design methods, obstacles, optimizations, and results for a new beat matching algorithm created for real-time use on embedded devices. This algorithm produces promising performance for use on portable media devices that often play modern musical genres.
