Stereo audio systems are widely used in different scenarios, especially for portable devices.
For their usability, it is important to develop algorithms capable of improving audio
performance. In this context, the proposed system aim to enhance spatial sound
reproduction taking advantages of three psychoacoustic effects. Starting from a virtual bass
algorithm used to increase the perception of lowest frequencies exploiting the missing
fundamental phenomenon, a stereo enhancer is used to add a spatialization effect to sound …
