Abstract: Beat detection systems and onset detections are used in music information retrieval (MIR) research field for the calculation of the global tempo (GT) and beat positions in audio recordings. The aim of this article is to introduce the enhancement of the onset detector and therefore the beat tracking system. The enhancement is based on the Teager-Kaiser energy operator (TKEO), which is used in pre-processing stage before the onset computation. The proposed method is firstly evaluated in terms of ability to estimate GT of a given audio track and then it is tested on the string quartet database. Results suggest that the TKEO could improve accuracy of GT estimation. Proposed beat tracking system could be used for analysis of interpretation changes in string quartet music.
