Implementation of Virtual Sound Source Considering Acoustic Path

Abstract — Development of acoustic systems is a necessitate which require research over audio and speech processing. A novel and interesting concept in the real of acoustic systems is controlling room acoustic path. It means to orient the sound locally in a room to a desired person without annoying others and without using headphone. Room acoustic path enable us to create personal sound space in a specific location of the room. In our former research, we convert two input signals into three output signals. The output signals finally conclude two separated personal sound spaces by using a crosstalk cancellation pre-filter. Our research aimed to reach observed signals at each of two points independent from the other one. Up to the time, only room acoustic attenuation and phase shift was considered between speaker and observer. However, the acoustic impulse response was ignored. So, we considered the acoustic impulse response in this system which does not require the setting state of the speaker. In our new research we realize the above system. The research has two parts, hardware implementation and practical investigation of the realized system.
