[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound browsing apparatus and method for acquiring necessary sound data from a large amount of sound data such as voices, sound effects, and music on a display device.

[0002]

2. Description of the Related Art Conventionally, among many acoustic data,
There is a system that can appropriately select acoustic data desired by a user and confirm it by hearing, and is used in fields such as multimedia content production support.

[0003] However, with the rapid progress of computerization technology in recent years, the volume of audio data to be handled by such a system has been dramatically increased, and among these huge audio data, the audio data that the user truly wants is desired. It is becoming difficult to choose the right one.

[0004] In order to overcome such adverse effects, an acoustic browsing apparatus capable of performing an acoustic search by utilizing an acoustic spatial arrangement technique has been devised. This is done by first performing a sensitivity word evaluation experiment based on the SD (Semantic Differential Method) method for short-time sound effects, and applying a general method based on factor analysis and a self-organizing map to the obtained evaluation values. It is trying to arrange the space by the method. At the time of sound search, spatial sound reproduction is introduced, and the desired sound data is reproduced by selecting and clicking the sound data icon displayed on the screen.

[0005]

However, in the above-described sound browsing apparatus, it is impossible to predict what kind of sound data the sound data displayed by the icon is without actually reproducing the sound data. Also, there is no judgment as to whether or not the sound data desired by the user is approaching. Therefore, there is a problem that considerable skill is required to reach the audio data that the user really wants, and it may be difficult to utilize the data in practical use.

According to the present invention, in order to solve the above-mentioned problems, it is possible to intuitively judge where sound data desired by a user is stored, and to easily obtain the sound data without skill.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An acoustic browsing apparatus according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of an acoustic browsing apparatus according to an embodiment of the present invention. In FIG. 1, 11 denotes an acoustic data storage unit, 12 denotes an acoustic space coordinate data generating unit, 13 denotes an acoustic space coordinate data storing unit, 14 denotes an icon image generating unit, 15 denotes an acoustic data display unit, and 16 denotes an acoustic data display unit. An acoustic space coordinate input unit, 17 is a stereophonic sound reproduction processing unit, and 1 is
Reference numeral 8 denotes an acoustic data reproducing unit.

In FIG. 1, a sound data storage unit 11 stores a set of sound data itself, an icon image used for displaying the sound data on a screen, and a sound feature amount of the sound data. .

The acoustic feature is not only a physical feature such as a frequency and a spectrum related to acoustic data, but also a sensible feature which a person feels when hearing sound, for example, "pleasant".
A feature amount indicating a degree such as “powerful” or “high” is also meant.

On the basis of the acoustic features, the acoustic space coordinate data generating unit 12 generates coordinate data of the acoustic data in the acoustic space to be displayed on the screen. That is, the position at which the sound data should be displayed in the sound space is calculated.

Specifically, the acoustic space itself must be created first. In order to create an acoustic space, an evaluation scale is configured using a plurality of evaluation words. For example, using the evaluation words such as “loud”, “beautiful”, and “clear” which are sensibility words, the degree of contribution of various sounds is evaluated. Here, the contribution rate means the ratio of each eigenvalue to the sum of eigenvalues obtained from the correlation matrix, and the evaluation of the contribution rate itself is evaluated based on the evaluator's own sensitivity. Therefore, it can be determined that the higher the contribution ratio is, the more the sound has a sensitivity closer to the evaluation word.

However, if the number of evaluation words is large, the evaluation dimension becomes higher as the number of evaluation words increases. Therefore, the amount of sensitivity which can be a factor for analysis to simplify the display is determined, and each evaluation word is determined. Perform factor analysis. Therefore, it is possible to map acoustic data using n evaluation words onto a space composed of several factors.

Next, by performing factor analysis on each evaluation word and calculating the load amount for each factor, it is possible to determine at which position in the acoustic space the respective acoustic data is located with each factor as an axis. Can be. In the present embodiment, since there are three factors, it is possible to display in three-dimensional space coordinates.

For example, considering an arrangement in a right-handed reference system in which the first factor axis is in the right direction, the second factor axis is in the upward direction, and the third factor axis is in the forward direction, the evaluation target is obtained using the coordinate values of the factor axes as clues. Can be searched for.

Here, the creation of the acoustic space using the factor analysis has been described. However, the present invention is not particularly limited to this. For example, the acoustic data distribution is displayed as a two-dimensional space, and the creation date of the acoustic data is displayed. Alternatively, a method of generating a pseudo three-dimensional space by adding one navigation axis may be used.

The acoustic space coordinate data generated by the acoustic space coordinate data generating unit 12 is stored in the acoustic space coordinate data storage unit 13 to be displayed on the screen, and is referred to when displaying the acoustic data on the screen. . Also at the time of reproducing the sound data, the sound data is referred to when selecting the sound data to be reproduced and determining the volume of the reproduction sound. In the present embodiment, the acoustic space coordinate data and the acoustic data are stored separately, but may be stored in the same database without separately storing them.

Next, the icon image to be displayed on the screen is
It is automatically generated by the icon image generation unit 14 based on the acoustic feature amount. Specifically, an icon is displayed so that the physical feature amount and the sensible feature amount can be intuitively grasped by the icon image.

In the present embodiment, generation of an icon image based on a 3 × 3 square is shown. First, the background color of the icon image is determined based on the sensible feature amount. That is, three main kansei parameters representing the acoustic data to be displayed are selected, and three color arrangement patterns are determined for the kansei parameters based on the kansei of the evaluator using colors that can image the characteristics of the sound. I do. Then, the color arrangement patterns are displayed in three stages without changing the order.

For example, with respect to certain acoustic data, representative sensibility parameters are “high”, “powerful”,
If there are three “noisy”, three color arrangement patterns are determined for each sensitivity parameter. For example, the sensitivity parameter of "high" is "blue", "yellow", "reddish purple", and the sensitivity parameter of "powerful" is "red", "gold", "dark green", "high""Red" for the parameter,
The color scheme is uniquely determined, such as "yellow" or "green".

Next, the amplitude pattern of the sound data is drawn based on the physical feature amount, and the drawing position is displayed up and down according to the spectrum distribution. For example, for certain acoustic data, if the amplitude pattern is a “smooth attenuation” pattern and its spectral distribution is in the middle range, the display is as shown in FIG. A display icon as shown in FIG. 3 is completed by superimposing a color scheme of the background determined based on the sensible feature amount.

By using such display icons, the following advantages can be enjoyed. That is, first, the sound data whose representative sensibility parameters are similar are arranged at a position close to the sound space, and it is possible to continuously search for the sound data having similar sensibility. . Further, since the characteristics of the sound data can be inferred from the background color of the icon without actually reproducing the sound data, it is easy to find a position in the sound space where the sound data to be obtained is located.

The display icon image generated by the icon image generation unit 14 is stored in the audio data storage unit 11 as an icon image for displaying the audio data.

When the three items of sound data, icon image, and sound space coordinate data are prepared, the sound data can be displayed on the sound data display unit 15. In the sound data display unit, for example, by displaying the icon generated by the icon image generation unit 14 on the sound space as shown in FIG. 4, the position where the sound data exists can be confirmed, and the sound data can be searched. can do. In FIG. 4, the icon is not displayed using the newly generated icon. However, the icon displayed in an elliptical shape in FIG. 4 is replaced with the icon shown in FIG. 3 and displayed.

When a user reproduces sound data,
Conventionally, it was necessary to select the displayed sound data icons and reproduce them one by one. In the present embodiment, the user first specifies acoustic space coordinates from the acoustic space coordinate input unit 16. The input may be a numerical input using an input medium such as a keyboard, but generally a pointer input using an input medium such as a mouse is mainstream.

When the acoustic space coordinates are inputted from the acoustic space coordinate input unit 16, the inputted spatial coordinates are compared in the stereophonic sound reproduction processing unit 17 by comparing the inputted spatial coordinates with the acoustic space coordinates of the acoustic data. And reproduces sound data at a distance equal to or less than a certain threshold value, and raises or lowers the reproduction volume according to the magnitude of the distance.

Then, in the sound data reproducing unit 18,
It becomes possible to reproduce sound data corresponding to the input sound space coordinates. In this case, if the mouse or the like is continuously moved, the sound data to be reproduced also changes continuously.
That is, the volume of the reproduced sound data changes,
At the same time, the sound data to be reproduced is increased or decreased, or the sound data to be reproduced is changed.

The reproduced synthesized sound can be stored in the acoustic data storage unit 11 as new acoustic data. In this case, the user can select and save, or can save automatically.

Next, an acoustic browsing apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 5 shows a configuration diagram of the acoustic browsing apparatus according to the embodiment of the present invention. In FIG. 5, 51 is an acoustic data storage device, 52 is an acoustic space coordinate data generation device, 53 is an acoustic space coordinate data storage device, 54 is an icon generation device, 55 is a CRT, 56 is an input device, Reference numeral 57 denotes a three-dimensional sound reproduction device, and 58 denotes a sound reproduction device.

FIG. 5 is basically the same as that of FIG. 1, except that an input device 56 uses an input medium such as a keyboard and a mouse, and a sound reproducing device 58 uses speakers and headphones via a sound board. ing. With the input device 56, a viewpoint moving operation of the acoustic space displayed on the CRT 55 can be performed, and the acoustic space display can be changed in real time.

In FIG. 5, the acoustic data storage device 51 stores the acoustic data itself, an icon image used when displaying the acoustic data on the screen, and an acoustic feature amount of the acoustic data as a set. .

Based on the acoustic features, the acoustic space coordinate data generating device 52 generates coordinate data of the acoustic data in the acoustic space to be displayed on the screen. That is, the position at which the sound data should be displayed in the sound space is calculated.

In this embodiment, in order to create an acoustic space, factor loads are obtained by factor analysis using evaluation words such as "large", "beautiful", and "clear", which are sensitivity words. . The varimax rotation is performed so that the first, second, and third factors to be axes of the acoustic space can be described by as few evaluation variables as possible, in other words, so that a small number of evaluation variables overlap as many as three factor axes. Do. As a result of the factor analysis for the evaluation value in the present embodiment, the original factor loading and the factor loading after varimax rotation are shown in (Table 1).

[0039]

[Table 1]

After performing the factor analysis in this way, considering the arrangement in a right-handed reference system in which the first factor axis is to the right, the second factor axis is to the upper direction, and the third factor axis is to the front, It is possible to search for acoustic data to be evaluated using the coordinate values of the axes as clues.

The acoustic space coordinate data generating device 52
Are stored in the acoustic space coordinate data storage device 53 to be displayed on the screen, and are referred to when displaying the acoustic data on the screen. Also at the time of reproducing the sound data, the sound data is referred to when selecting the sound data to be reproduced and determining the volume of the reproduction sound.

Next, the icon image to be displayed on the screen is
The icon is automatically generated by the icon generation device 54 based on the acoustic feature amount. Specifically, an icon is displayed so that the physical feature amount and the sensible feature amount can be intuitively grasped by the icon image.

Also in this embodiment, an icon image based on a 3 × 3 square is generated, and an icon image as shown in FIG. 3 is uniquely generated for each sound data.

With such a display icon, sound data having similar sensibility parameters are arranged at a position close to the sound space, and sound data having the same sensibility are continuously displayed. Search. Further, since the characteristics of the sound data can be inferred from the background color of the icon without actually reproducing the sound data, it is easy to find a position in the sound space where the sound data to be obtained is located.

The display icon image generated by the icon generation device 54 is stored in the audio data storage device 51 as an icon image used when displaying the audio data in the audio space.

When the three items of sound data, icon image and sound space coordinate data are prepared, the sound data can be displayed on the CRT 55. In the CRT 55, for example, by using an icon image generated by the icon generation device 54 in an acoustic space as shown in FIG.
It is possible to confirm the position where the sound data exists, and to search for the sound data. FIG.
Is not displayed using the newly generated icon, but the icon displayed in an elliptical shape in FIG. 4 is actually replaced with an icon as shown in FIG. 3 and displayed.

The user first specifies the acoustic space coordinates to be reproduced from the input device 56. The input may be a numerical input using an input medium such as a keyboard, but generally a pointer input using an input medium such as a mouse is mainstream.

When the sound space coordinates are input from the input device 56, the three-dimensional sound reproduction processing device 57 compares the input space coordinates with the sound space coordinates of the sound data so that the input space coordinates are fixed. The sound data at a distance equal to or less than the threshold value is reproduced, and the reproduction volume is increased or decreased according to the magnitude of the distance.

The sound data reproducing device 58 can reproduce sound data corresponding to the input sound space coordinates. Specifically, a sound board or the like is provided, and the user can listen to the reproduced sound data through the connected speakers or headphones. If the mouse or the like is continuously moved, the sound data to be reproduced also changes continuously. That is, the volume of the reproduced audio data changes, the amount of the reproduced audio data increases / decreases, or the reproduced audio data changes.

As described above, according to the present embodiment, it is possible to search for the sound data to be obtained while confirming the position between the sound data by spatially displaying a large amount of sound data in a three-dimensional manner. Becomes In addition, by displaying the icon in accordance with the feature amount of the sound data, it is possible to search for the sound data to be obtained without reproducing.

The acoustic browsing apparatus according to the present embodiment has a wide range of application, and examples of application in various fields are conceivable. The following embodiments can be considered as main application examples.

First, use as an audio data editing tool is conceivable. This reflects the human sensibility, which is difficult to quantify, in the audio data editing, and changes the value of each factor axis for the audio data to be edited by slider operation, mouse operation, etc. However, it is possible to edit sound data that matches the user's sensitivity.

The present invention can also be used for generating a new sound material by mixing sound data. This makes it possible to reproduce the sound data while smoothly changing the sound data by overlapping the specific sound data with other sound data.

Further, it can be used as a design support tool for an acoustic space. For example, in the design of a hall or a performance hall, it is expected that a simulation can be easily performed on how sound data changes and sounds depending on the use ratio and use position of a sound absorbing material or a reflecting material.
