Tempoexpress: an expressivity-preserving musical tempo transformation system
Maarten Grachten, Josep Lluís Arcos, Ramón López de Mántaras · 2006
The research described in this paper focuses on global tempo transformations of monophonic audio recordings of saxo-phone jazz performances. More concretely, we have inves-tigated the problem of how a performance played at a partic-ular tempo can be automatically rendered at another tempo while preserving its expressivity. To do so we have devel-oped a case-based reasoning system called TempoExpress. The results we have obtained have been extensively compared against a standard technique called uniform time stretching (UTS), and show that our approach is superior to UTS.
