A virtual 3D sound generating apparatus and method, which can be easily applied to portable devices such as headphones and earphones. The method includes delaying a first input signal for a first time corresponding to a distance between a first virtual sound source and the left ear of a virtual listener, and delaying a second input signal for a second time corresponding to a distance between a second virtual sound source and the right ear of the virtual listener. Accordingly, a maximum virtual 3D sound effect can be obtained using a minimum number of elements by delaying signals for different amounts of time to simulate geometrical asymmetry of a real listening space.
