Multiband room effect simulator for 5.1-channel sound system

The paper investigates a new room effect simulator with different quality of audio sound sources for a 5.1-channel sound system. The audio effect relates its impulse response with different room dimensions. A multiband equalizer is designed to generate many kinds of music impressions. We also modify the mono Dolby surround decoder into a simplified surround decoder so that the stereo room simulator can generate 5.1-channel surround outputs. All experiments are at a sampling rate of 44.1 kHz and 16 bits per sample. By the room effect simulator, we can get a full and a live listening experience.
