Paper abstract


A Method to Convert Stereo to Multichannel Sound System


Roy Irwan and Ronald M. Aarts
Philips Research, Eindhoven, The Netherlands

While stereo music reproduction was a dramatic advance over mono, the transition to multichannel audio has created a more involved experience for listeners. Space mapping can be employed as a process to enhance the conversion from stereo to multichannel sound reproductions. A better sound distribution to the surround channels is achieved by using the cross-correlation technique.
