Abstract: A method for producing an electronically-simulated live musical performance, the method comprising providing morph-friendly solo tracks, morphing the morph-friendly solo tracks to produce a morphed track, and post-processing the morphed track. The method may also include combining the post-processed morphed track with one or more supporting tracks to produce an acoustic image for playback.

Abstract: An apparatus (402) and method for measuring a surface energy of a test surface (12), which includes a viscoelastic polymer layer (20), disposed on a moveable component (34), that is compressed against the test surface (12) with a compressive force. The moveable component (34) is then moved relative to the test surface (12) at a predetermined velocity, and a drive force applied to the moveable component (34) is measured. The surface energy of the test surface (12) is then determined based at least in part on the compressive force, the predetermined velocity, and the measured drive force.
