Further, the CPU 14 controls the operation of the sound adjustment visualizer displayed on the
display device 10 in accordance with the operation of the pointing device 12.
[0022]
Here, the sound adjustment visualizer displayed on the display device 10 (hereinafter, simply
referred to as a visualizer.
Will be described.
[0023]
For example, as shown in FIG. 2, the visualizer comprises a conical GUI image, and as described
above, the shape state changes appropriately according to the information contained in the
sound, and Has a sound adjustment function to adjust the sound.
The relationship between the shape and the state change is merely an example, and the shape
may be another shape as shown in FIG. 3 other than the conical shape, and various state changes
can be considered.
In FIG. 3, the shape changes in response to the sound in the low range in the Visualizer a, the
shape changes in response to the sound in the middle range in the Visualizer b, and the sound
changes in the high range in the Visualizer c. Shape changes.

Specifically, the user operates the pointing device 12 to move the conical visualizer in a
predetermined direction, and adjust the sound by changing the state of the shape and the
coordinate position.
[0025]
In addition, as shown in FIG. 2, the conical shape visualizer has an upper right portion A, an
upper left portion B, a central right portion C, a central left portion D, a lower right portion E, and
a lower left portion F And a lowermost portion G, and a table is stored in the ROM 16 to which
adjustment values are associated corresponding to the change in shape of each part.
As shown in FIG. 4, the table stored in the ROM 16 is associated with the state of the sound with
respect to the state of the visualizer.
[0026]
When the CPU 14 selects any part of the conical visualizer by the pointing device 12 during
sound reproduction, and the selected portion is moved (changed) by dragging or the like, the
position after the change (change) The (state) is read, and a setting value corresponding to the
position (state) is determined with reference to the above table, and a sound is generated based
on the difference between the setting value before movement (change) and the setting value after
movement (change) Adjust the
[0027]

stop, fast forward, rewind, sound field setting, equalizing, sound select, various effect operations
(reverb, chorus, etc.) There are distortion, flanger, delay, overdrive, phaser etc.
[0029]
Therefore, the user can perform the adjustment operation of the sound output from the sound
output unit 13 intuitively and visually by the operation of the pointing device 12.
[0030]
Here, the significance of making a visualizer having a sound adjustment function into a threedimensional shape will be described.
Conventional visualizers for sound adjustment are displayed and operated almost flat on sliders
and buttons for adjustment, etc., so it was difficult to grasp the state of sound adjustment at first
glance.
Therefore, as in the present invention, by expressing it in a three-dimensional shape, it is possible
to grasp the adjustment situation of the sound at first glance, and it is possible to adjust the
sound by the intuitive operation by the user's vision.
[0031]
Further, as an example of intuitive operation, when it is desired to increase the sound volume
(UP), as shown in FIG. 6, the basic visualizer A is enlarged by the operation of the pointing device
12 (A1 in FIG. 6). Or may be realized by lengthening (A3 in FIG. 6), or when it is desired to
decrease the volume of the sound (DOWN), the basic visualizer A may be used as the pointing
device 12). The configuration may be realized by downsizing (A2 in FIG. 6) or shortening (A4 in
FIG. 6) by operation.

[0032]
In addition, in the case where it is desired to emphasize the low range (woofer) in the sound
range, the configuration may be realized by squeezing the upper end of the visualizer by
operating the pointing device 12 (A5 in FIG. 6). In addition, when emphasizing the high range
(tweeter), the configuration may be realized by squeezing the lower end portion of the visualizer
by the operation of the pointing device 12 (A6 in FIG. 6).
[0033]
In addition, in the sound output unit 13, when it is desired to change the left-right output balance
and increase the output from the right side more than the left side, the configuration may be
realized by stretching the right side of the visualizer rightward. (A7 in FIG. 6).
[0034]
Further, in the case where the sound output unit 13 is configured by a plurality of speakers,
when adjusting the listening point, for example, as shown in FIG. 7, a virtual three-dimensional
space is displayed on the display device 10, and the three-dimensional space is displayed. The
same speaker configuration that is actually arranged in space is virtually displayed, and moving
the visualizer to an arbitrary listening point adjusts the volume of the sound output from each
speaker It may be a configuration.
According to such a configuration, the user can select an arbitrary listening point by an intuitive
operation.
[0035]
In addition, in the case of selecting content (sound data of a predetermined file type), for
example, as shown in FIG. 8, an object indicating each content is displayed on the virtual threedimensional space on the display device 10. The content may be selected by moving the
visualizer over the content of.
According to such a configuration, the user can select any content by intuitive operation.

predetermined file type by the reproduction program, reproducing the decoded sound data, and
adjusting the sound based on the reproduced sound data, A sound adjustment visualizer whose
state is deformed according to the adjustment amount by the sound adjustment and the
information included in the sound data is displayed on the display device 10 as a GUI and
displayed on the display device 10 for sound adjustment The visualizer is operated by a virtual
pointer, and in accordance with the operation, the state of the sound adjustment visualizer is
deformed, and the reproduced sound data is adjusted based on the deformed state of the sound
adjustment visualizer. , Which transforms in real time according to the sound being output Since
the sound is adjusted according to the deformation state, the sound can be easily adjusted to the
sound desired by the user, while viewing the clearer so as to change the state of the visualizer to
the sound desired by the user. Also, it makes it easy to grasp the situation of sound adjustment
by visuals.
Further, according to the present invention, since it is possible to adjust various parameters while
viewing a plurality of adjustment parameters simultaneously, it is possible to easily adjust to the
sound desired by the user also from this point.
