We briefly overview algorithms for obtaining, manipulating and inverting cortical representation of a sound and describe algorithms for manipulating signal pitch and timbre separately. ...
In this paper we use a recently proposed cortical representation to represent and manipulate sound. ...
A goal of this paper is the development of controls for independent manipulation of pitch and timbre of a sound source using a cortical sound representation that was introduced in [1] and used for assessment ...
