Transient / Steady-state Separation (TSS)
This file implement a Transient / Steady-state Separation (TSS) as described in:
Christopher Duxbury, Mike E. Davies, and Mark B. Sandler. Separation of transient information in musical audio using multiresolution analysis techniques. In Proceedings of the Digital Audio Effects Conference, DAFx-01, pages 15, Limerick, Ireland, 2001.
