The 2007 LabROSA Cover Song Detection System

We describe our cover song detection system, as submitted to the MIREX 2007 Cover Song Detection evaluation. The system is developed from our 2006 MIREX system, which was the best-performing entry in last year’s evaluation. Using the new “covers80” dataset of 80 pairs of songs and covers, we improve the overall detection from 42.5% to 67.5% through a collection of minor modificationsrelatingtocorrelationnormalization, tempotracking, andtemporalfilteringofthebeat-synchronouschroma representation.
