On the Multichannel Sinusoidal Model for Coding Audio Object Signals

Document Thumbnail

This paper presents two improvements on a recently proposed multichannel sinusoidal modeling system for coding multiple audio object signals. The system includes extracting the sinusoidal components and an LPC envelope for each object signal, as well as transform coding of the residuals' downmix. The contributions of this paper are: (a) a psychoacoustic model for enabling the system to scale well with multiple object signals, and (b) an improved method to encode the common residual, tailored to the "white" nature of this signal. As a result, sound quality of 90% on the MUSHRA scale is obtained for 10 simultaneous object signals coded with a total rate of 150 kbit/s, while retaining the individual object parametric representations.
