Abstract :
[en] Cover song identification systems deal with the problem of identifying different versions of an audio query in a reference database. Such systems involve the computation of pairwise similarity scores between a query and all the tracks of a database. The usual way of evaluating such systems is to use a set of audio queries, extract features from them, and compare them to other tracks in the database to report diverse statistics. Databases in such research are usually designed in a controlled environment, with relatively clean audio signals. However, in real life conditions, audio signals can be seriously modified due to acoustic degradations. For example, depending on the context, audio can be modified by room reverberation, or by added hands clapping noise in a live concert, etc. In this paper, we study how environmental audio degradations affect the performance of several state-of-the-arty cover song recognition systems. In particular, we study how reverberation, ambient noise and distortion affect the performance of the systems. We further investigate the effect of recording or playing music through a smartphone for music recognition. To achieve this, we use an audio degradation toolbox to degrade the set of queries to be evaluated. We propose a comparison of the performance achieved with cover song identification systems based on several harmonic and timbre features under ideal and noisy conditions. We demonstrate that the performance depends strongly on the degradation method applied to the source, and quantify the performance using multiple statistics.
