Abstract

Some of the significant solutions and application to the cocktail party problem are discussed. Computational Auditory Scene Analysis (CASA) is one of the solutions that is applied to solve the cocktail party problem. The classification procedure is based on simple approximations of four basic principles. These four basic principles include the inaugural time-difference (ITD), interaural intensity difference (IID), and pitch and temporal onset. The ITD can be computed through the cross-correlation and auto-correlation functions, while IID and onset are based on comparisons involving the signal's power envelope.
