Reference numeral 113 is a three-dimensional stereo sound processing module, which is a feature of the present invention, is connected to the main CPI 101, receives an audio signal from the audio switch 117, and processes and outputs a stereo signal.

The 3D stereo sound processing module 113 is also referred to as QBS (QbigSound TM) 3D Stereo audio processing module, and 3D Stereo is a real-time 3D audio positioning effect using a HRTF (Head Related Transfer Function) technology. . HRTF is known as a 'head function' and can be defined as a change in volume, frequency, or phase that is modified due to various conditions that may be affected in the process of transmitting a sound signal to the human ear. Conditions that can affect these signal changes refer to all three-dimensional relative positions between the sound source and the listener, and physical factors due to body structural effects such as head, nose, shoulder, and ear wheels. The research on HRTF started from the field of psychoacoustics, and it was limited to implementing 3D through special recording techniques or post-processing of audio in the past because the computational complexity, implementation complexity, and mathematical modeling were relatively difficult. Recent developments in high-speed processors have made it possible to implement real-time relatively recently.

With HRTF technology, 'Virtual Surround' can be implemented, so two stereo speakers can be processed as if the sound source is located in the virtual space. In other words, it can overcome the limitations of the space played by the physical speaker and can reproduce the realistic stereoscopic sound.

It is the latest acoustic technology that considers the direction including the diffuse feeling that can make the sound source exist in any position with respect to the listener.

Based on this, it is possible to listen to high-quality audio in the car by applying it in conjunction with karaoke, language school, and audiobook which are currently tried a lot.

Existing MP3 files have a high capacity of 3M or more, except for the map area and the AP area, many songs are not included in the 2G SD CARD. However, the system of the present invention supports MIDI files. Because of its small size, it can store and play 100 times more songs than MP3 files.
