<p><P>PROBLEM TO BE SOLVED: To provide a sound signal processor capable of identifying easily a selected sound pickup directivity and performing intuitively and simply switching operation for the sound pickup directivity. <P>SOLUTION: A posture sensor 11 generates posture data, according to the state where a chassis 2 is installed at an installation surface 100, and outputs the data to a controller 10. Based on the posture data, the controller 10 reads out a sound pickup directivity control parameter from a memory 12 and gives the parameter to a sound pickup controller 13. The sound pickup controller 13 has a sound pickup gain adjustment unit 131 and an adder 132, and adjusts gain of each of amplifiers 1311-1313 at the sound pickup gain adjustment unit 131, based on the sound pickup directivity control parameter. Thus, the amplifiers 1311-1313 amplify a sound pickup signal from microphones MIC1, MIC2, and MIC3, respectively, using the established gain. The adder 132 adds each amplified sound pickup signal to generates a directivity control sound pickup signal. Thereby, the directivity control sound pickup signal can be acquired, according to the posture of the chassis 2. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
