Title:
TERMINAL DEVICE AND AUDIO SIGNAL PROCESSING SYSTEM
Document Type and Number:
Japanese Patent JP2016100689
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To perform recording and reproduction of movement of a sound image with an intuitive and simple operation.SOLUTION: When a terminal device 10 is oriented to a movement start position of a sound image, and a movement button is pushed (S41), a rotational angle around a Z-axis, based on the direction of a Y-axis perpendicular to the Z-axis, and a slope angle around an axis which is perpendicular to an axis of the terminal device 10, directed from the terminal device 10 to a predetermined position and also perpendicular to the Z-axis are acquired while considering the rotational angle and the slope angle as angle information from a sensor of the terminal device 10. The terminal device 10 calculates position information on the basis of the angle information, and transmits the position information to an audio signal processor 20 (S42). Subsequently, the orientation of the terminal device 10 is changed so as to draw a locus of the sound image while pushing the movement button, and the position information is calculated on the basis of on the angle information for every predetermined sampling interval and transmitted to the audio signal processor 20.SELECTED DRAWING: Figure 6
