Abstract or Description

We present a way to make environmental recordings controllable again by the use of continuous annotations of the high-level semantic parameter one wishes to control, e.g. wind strength or crowd excitation level. A partial annotation can be propagated to cover the entire recording via cross-modal analysis between gesture and sound by canonical time warping (CTW). The annotations serve as a descriptor for lookup in corpus-based concatenative synthesis in order to invert the sound/annotation relationship. The workflow has been evaluated by a preliminary subject test and results on canonical correlation analysis (CCA) show high consistency between annotations and a small set of audio descriptors being well correlated with them. An experiment of the propagation of annotations shows the superior performance of CTW over CCA with as little as 20 s of annotated material.
