In digital audio playback systems for home entertainment, multimedia PC, game station and portable audio devices, there is a strong demand to produce deep bass using small multimedia speakers and earphones, without the need for additional subwoofer or expensive speakers/earphones. This paper describes a technique in synthesizing psycho-acoustic bass over a pair of stereo speakers using the pitch perception theory. This new method of creating a bass effect for the musical signal has been found to be very effective and simple in implementation, without increasing significant cost in many modern digital audio systems. A subjective evaluation is also being performed to validate the virtual bass implementation
