A signal processing apparatus (6) for a vehicle sound system (2) includes a signal input section (62), through which in operation a multi-channel audio signal is provided, the multi-channel audio signal having at least a left front signal (L F ), a left surround signal (Ls), a right front signal (R F ) and a right surround signal (R S ), a room simulation module (64) adapted to receive the multi-channel audio signal and to generate at least a left 3D signal (L F3D ) and a right 3D signal (R F3D ), with the room simulation module (64) having a left room simulation function generating the left 3D signal (L F3D ), with the left front signal (L F ) and the left surround signal (L S ) being inputs thereto, and a right room simulation function generating the right 3D signal (R F3D ), with the right front signal (R F ) and the right surround signal (Rs) being inputs thereto, and a signal output section (66) for outputting the left 3D signal (L F3D ) and the right 3D signal (R F3D ) to a left 3D speaker (25) and a right 3D speaker (26) disposed in an upper portion of a vehicle. |
