[0033] figure 1 is a schematic block diagram showing the overall structure of the sound data reproducing device 1 having a sound data retrieval support function.

[0034] The sound data reproducing device 1 includes operation switches 22 , a hard disk (HDD) 23 , an external information input / output section 24 , a CD drive 25 , a display section 26 , an audio amplifier 27 , a speaker 28 and a control unit 29 . The operation switch 22 receives an instruction operation command performed by the user, and the hard disk 23 stores various data including sound data. The external information input / output section 24 is capable of receiving information items from other devices than the sound data reproducing device 1, or outputting information to another device. The display unit 26 displays various information. The audio amplifier 27 and the speaker 28 are used to output various sounds. Based on various information items and data items including instructions input from the operation s...

[0096] Figure 9A An example of a virtual space formed on the basis of a two-dimensional orthogonal coordinate system having an X axis (horizontal axis) representing beats and a Y axis (vertical axis) representing categories is shown. can make in Figure 9A The search points used in the virtual space shown are free to move on X-Y coordinates or can only jump between X-Y coordinate points.

[0097] exist Figure 9B In another example of the virtual space shown, if there is no music data in a certain area in the coordinate system, that area is covered by the closest sound field or the closest sound field with the same category and tempo, which enlarges the sound field. As a result, the search point used in the virtual space is only allowed to jump between X-Y coordinate points, regardless of the position of the search point, the sound can always be heard. In other words, referring to Figure 9B , the sound is always heard regardless of the position of the search point, in th...

[0099] Figure 10 It is shown by using a two-dimensional orthogonal coordinate system (similar to Figure 9A and 9B An example of a three-dimensional virtual space formed by adding the Z axis to a position in the two-dimensional virtual space shown in the coordinate system shown in . In this three-dimensional virtual space, when there are multiple pieces of music with the same category and the same tempo, a Z axis perpendicular to both the X axis and the Y axis is added so that multiple pieces of music data representing multiple pieces of music can be stacked along the Z axis . The search points used in the three-dimensional virtual space can be configured so that when a predetermined operation is performed using the operation switch 22, the search points can be moved in a predetermined order to sequentially find pieces of music data having the same category and tempo.

Abstract

A sound data retrieval support device includes an operation receiving unit, a sound output unit, and a control unit. The sound data retrieval support device supports the user in retrieving a desired sound data item among a plurality of sound data items. The each of the plurality of sound data items is associated with a location and a sound field in the virtual space based on attribute information items of the sound data item. The control unit causes a search point to be moved in the virtual space based on the operation command received via the operation receiving unit. The control unit causes the sound output unit to output sound that corresponds to one of the plurality of sound data items. The search point is located in the sound field of the one of the plurality of sound data items.

Description

technical field [0001] The present invention relates to a sound data retrieval support device. Background technique [0002] Conventionally, recording media such as optical discs have been used to process and reproduce sound data. However, with the widespread use of large-capacity devices such as hard disks and flash memories (hereinafter, collectively referred to as "hard disks"), the amount of data that can be recorded on media has been increasing. Therefore, sound data reproducing apparatuses have been studied in order to record sound data on a hard disk and reproduce desired music from the hard disk. [0003] The hard disk can be used at a high access speed, and music data recorded on the hard disk can be reproduced in a desired order. Thereby, sound data recorded on a plurality of music CDs can be recorded on a hard disk, and songs recorded from a plurality of music CDs can be classified, for example, by title or artist name. Since the data recorded on the hard disk ...
