1.1 FULLY AUTOMATIC LOUDSPEAKER-ROOM ADAPTATION – the RoomPerfect system

Most systems for Loudspeaker-Room adaptation require the user to interact significantly with the system during the setup procedure. More specifically the user has to make crucial decisions like choosing a target function and/or editing the raw measurements before filter calculation. This is a result of systems relying on too little information about the 3D acoustic problem to be solved, e.g. by measuring sound pressure in only one position in the listening room. The presented system overcomes this problem by acquiring information both of local properties at the listening position and on the acoustic power in the 3D sound field. This enables a fully automatic calculation of target function and no interaction required from the user.
