Apparatus and method of processing multi-channel audio input signals to produce at least two channel output signals therefrom, and computer readable medium containing executable code to perform the method

摘要: An apparatus to process m-channel audio input signals produce n channel output signals, and is less than m. This includes a first filter unit reduce correlation between at least two among the virtual sound source generation transform from into sources predetermined positions around listener position, an controller control other based on gains delays of signal unit. Even when are reproduced through 2 channels, surround effect provided by speaker system can be obtained. In addition, localization improved, presence formed. Thus, enhanced listener.
