A COMPARISON BETWEEN FIXED AND MULTIRESOLUTION ANALYSIS FOR ONSET DETECTION IN MUSICAL SIGNALS
Chris Duxbury, Juan Pablo Bello, Mark B. Sandler, Mike E. Davies · 2004
A study is presented for the use of multiresolution analysis-based onset detection in the complex domain. It shows that using variable time-resolution across frequency bands generates sharper detection functions for higher bands and more accurate detection functions for lower bands. The resulting method improves the localisation of onsets on fixed-resolution schemes, by favouring the increased time precision of higher subbands during the combination of results.
