Generally, the adjustable range (range) of each sound effect parameter is predetermined. When the values of the plurality of sound effect parameters are adjusted within such a constant range, a change in sound such as noise that is not intended by the user may occur depending on the combination of the values of the sound effect parameters. If the user is familiar with the relationship between multiple sound effect parameters, it is possible to adjust the value of each sound effect parameter within an appropriate range. Difficult to do.

An object of the present invention is to provide a sound effect control device, a sound effect control program, and a sound effect control method capable of appropriately controlling sound effects by a simple operation without requiring special knowledge. ..

Therefore, the user can appropriately control the acoustic effect without causing any discomfort in hearing with a simple operation without requiring special knowledge.
Also, whether or not a plurality of types of parameters are linked depends on the type of acoustic effect. Therefore, with respect to the acoustic effect in which the change of the sound that is not intended by the user is unlikely to occur, the acoustic effect can be controlled with a high degree of freedom by independently adjusting a plurality of types of parameters.

The parameter value determination means may determine the value of the parameter corresponding to the other operator based on the range of the parameter corresponding to the other operator and the state of the other operator.

In this case, the user can arbitrarily adjust the value of the parameter corresponding to the other operator within an appropriate range depending on the value of the parameter corresponding to the reference operator by operating the other operator. You can

(2) Functional Configuration of Acoustic Effect Control Device 100 FIG. 2 is a diagram for explaining the functional configuration of the acoustic effect control device 100 according to the embodiment of the present invention. As shown in FIG. 2, in the present embodiment, three operators 7 that are rotary encoders are provided. Hereinafter, in order to distinguish the three operators 7, the three operators 7 are referred to as operators 7A, 7B, and 7C, respectively. Each of the operators 7A to 7C has a convex reference portion ST. An arcuate scale SC is provided so as to surround the outer circumference of each of the operators 7A to 7C. One end SCa of the scale SC corresponds to the lower limit value of the adjustable range of parameter values (hereinafter referred to as the operation range) corresponding to each operator, and the other end SCb corresponds to the upper limit value of the operation range. The user rotates the operating elements 7A to 7C to align each reference portion ST with an arbitrary position between one end SCa and the other end SCb of the scale SC. Hereinafter, the position of the scale SC indicated by the reference portion ST of the operators 7A to 7C will be referred to as the scale position.

When the CPU 11 of FIG. 1 executes the sound effect control program stored in the ROM 10 or the storage device 13, the reference operator setting unit 21, the operation detection unit 22, the selection unit 23, the sound effect information acquisition unit 24, and the parameter type acquisition. Functions of the unit 26, the parameter value determination unit 27, and the parameter output unit 28 are realized. These functional units may be realized by hardware such as an electronic circuit.

The reference operator setting unit 21 sets one of the operators 7A to 7C as a “reference operator”. Details of the “reference operator” will be described later. The operation detection unit 22 detects an operation of the setting operation unit 4 and the operators 7A to 7C of FIG. The operation detection unit 22 also detects the states of the operators 7A to 7C. In this example, the states of the operators 7A to 7C correspond to the scale positions of the operators 7A to 7C. The selection unit 23 receives the selection of the sound effect type based on the operation of the setting operation unit 4 detected by the operation detection unit 22. The sound effect information acquisition unit 24 acquires sound effect information corresponding to the selected sound effect type. For example, sound effect information corresponding to all sound effect types is stored in advance in the storage device 13 of FIG. In that case, the sound effect information acquisition unit 24 reads the corresponding sound effect information from the storage device 13. The acoustic effect information may be acquired from the external storage device 15 by the communication I/F 14 or may be acquired via a communication network.

The parameter type acquisition unit 26 acquires a plurality of types of acoustic effect parameters (hereinafter, referred to as parameter types) corresponding to the operators 7A to 7C based on the acquired acoustic effect information. The parameter value determination unit 27 determines a plurality of parameter values respectively corresponding to the operators 7A to 7C. In this case, the parameter value determination unit 27 determines whether to link a plurality of types of acoustic effect parameters based on the acquired acoustic effect information. When interlocking a plurality of types of sound effect parameters, the parameter value determination unit 27 determines the operation range of the parameter values corresponding to the other operators 7 based on the parameter value corresponding to the “reference operator”.

The parameter output unit 28 outputs the parameter type and the parameter value corresponding to the operators 7A to 7C as acoustic effect data. The sound effect data output from the parameter output unit 28 is given to the effect circuit 17 of FIG. In the effect circuit 17, the parameter value stored in the register corresponding to the given parameter type is updated to the given parameter value.

(3) Sound effect information FIG. 3 is a diagram for explaining an example of the sound effect information. FIG. 3 shows sound effect information corresponding to “Low Pass Filter” and “Delay”, which are examples of sound effect types. In FIG. 3, the sound effect parameter corresponding to the operator 7A is represented as “parameter A”, the sound effect parameter corresponding to the operator 7B is represented as “parameter B”, and the sound corresponding to the operator 7C is represented. The effect parameter is represented as “parameter C”. Priorities are set for the operators 7A to 7C. In the example of FIG. 3, the priorities of the operators 7A, 7B, and 7C are set to the first, second, and third positions, respectively. The priority may be fixed or changeable. Further, the priority order of the operators 7A to 7C may be set for each sound effect type.

Each piece of acoustic effect information includes the parameter types of parameters A to C and the reference range. The reference range is a reference range that is predetermined for each parameter type, and is, for example, the maximum operation range. For example, the sound effect information corresponding to “Low Pass Filter” includes “Cutoff Frequency”, “Resonance”, and “Dry/wet” as parameter types, and “10 Hz to 20 kHz” and “−” as reference ranges of these. 20 dB to +20 dB" and "0% to 100%".

In addition, each sound effect information includes interlocking information indicating whether or not to interlock a plurality of sound effect parameters. In the following description, regarding the two sound effect parameters corresponding to the n-th (n is a positive integer) manipulator 7 and the n+1-th manipulator 7, the sound effect parameter corresponding to the n-th manipulator 7 is ranked higher. And the sound effect parameter corresponding to the n+1th operator 7 is called a lower parameter. When the interlocking information is ON, the operation range of the lower parameter changes depending on the value of the upper parameter. In this example, the operating range of the parameter B depends on the value of the parameter A, and the operating range of the parameter C depends on the value of the parameter B. Details of interlocking the sound effect parameters will be described later. When the interlocking information is off, the operation range of each sound effect parameter does not depend on the values of other parameters.

The sound effect information further includes a change mode of the operation range of the lower parameter when the interlocking information is on. In the example of FIG. 3, the acoustic effect information corresponding to “Low Pass Filter” includes “pattern A” and “pattern B” as the changing modes of the parameters B and C. The change mode of the operation range is represented by, for example, a map, a table, or a mathematical formula. Note that in this example, ON/OFF of the interlocking information is predetermined for each sound effect type, but the user may be able to switch the ON/OFF of the interlocking information.

(4) Interlocking acoustic effect parameters Interlocking a plurality of acoustic effect parameters will be specifically described. Here, an example in which the acoustic effect type is “Low Pass Filter” and the operation range of the parameter B (“Resonance”) changes depending on the value of the parameter A (“Cutoff Frequency”) will be described.

FIG. 4 is a diagram showing the relationship between the states of the operators 7A and 7B and the values of the parameters A and B. FIG. 5 is a diagram illustrating an example of how the operating range of the parameter B changes. The example of FIG. 5 corresponds to the pattern A of FIG. In FIG. 5, the horizontal axis represents the value of the parameter A, and the vertical axis represents the upper limit value of the operation range of the parameter B. The straight line L1 represents the relationship between the value of the parameter A and the upper limit value of the operation range of the parameter B. Specifically, as the value of the parameter A increases, the upper limit value of the operation range of the parameter B linearly decreases. In this example, the operating range of the parameter B changes so that the absolute value of the lower limit value becomes equal to the upper limit value.

The operation range of the parameter A corresponding to the operator 7A having the highest priority matches the reference range. Therefore, in the example of FIGS. 4A and 4B, the operation range of the parameter A is “10 Hz to 20 kHz”. Within the operation range of the parameter A, the value of the parameter A is determined based on the state of the operator 7A. In the example of FIG. 4A, the value of the parameter A is “TA1”, and in the example of FIG. 4B, the value of the parameter A is “TA2”.

As shown in FIG. 5, when the value of the parameter A is “TA1”, the upper limit value of the operation range of the parameter B is “+TB1r”, and when the value of the parameter A is “TA2”, the operation of the parameter B is performed. The upper limit value of the range is “+TB2r”. Therefore, in the example of FIG. 4A, the operation range of the parameter B is “−TB1r to +TB1r”, and in the example of FIG. 4B, the operation range of the parameter B is “−TB2r to +TB2r”. ..

Within the operation range of the parameter B, the value of the parameter B is determined based on the state of the operator 7B. In the example of FIG. 4A and the example of FIG. 4B, the states of the operators 7B are the same. However, the operation ranges of the parameter B are different from each other. Therefore, the value of the parameter B is also different. In the example of FIG. 4A, the value of the parameter B is “TB1”, and in the example of FIG. 4B, the value of the parameter B is “TB2”.

In the example of FIG. 5, when the value of the parameter A is the lower limit value “10 Hz”, the upper limit value of the operation range of the parameter B is “+TB3r”. “+TB3r” is, for example, the upper limit value “20 (dB)” of the reference range of the parameter B.

In this way, the operation range of the lower parameters is determined based on the values of the upper parameters. In the example of FIGS. 4 and 5, the operation range of the parameter B is determined based on the value of the parameter A, but similarly, the operation range of the parameter C is determined based on the value of the parameter B.

In the example of FIG. 5, the lower and upper limits of the operation range of the lower parameter (“Resonance”) change depending on the value of the upper parameter (“Cutoff Frequency”), but the operation of the lower parameter Only one of the lower limit value and the upper limit value of the range may change. For example, when “Dry/Wet” in FIG. 3 is a lower parameter, the lower limit value of the operation range of the lower parameter is fixed to the lower limit value “0%” of the reference range, and the upper parameter (“Resonance”) Depending on the value of, only the upper limit value of the operation range of the lower parameter may change.

Further, in the example of FIG. 5, since the upper limit value of the operation range of the parameter B is equal to the absolute value of the lower limit value, the lower limit value is uniquely determined by determining the upper limit value of the operation range based on the straight line L1. However, the upper limit value and the lower limit value of the operating range may be independently determined. For example, a straight line representing the upper parameter value and the upper limit value of the operating range of the lower parameter, and a straight line representing the upper parameter value and the lower limit value of the operating range of the lower parameter may be set separately. ..

FIG. 6 is a diagram showing another example of how the operating range changes. 6A to 6C, the horizontal axis represents the value of the upper parameter, and the vertical axis represents the upper limit value or the lower limit value of the operation range of the lower parameter. Differences between the example of FIGS. 6A to 6C and the example of FIG. 5 will be described. In the example of FIGS. 6A and 6B, the relationship between the value of the upper parameter and the operation range of the lower parameter is represented by curves L1a and L1b instead of straight lines. In the example of FIG. 6C, as indicated by the straight line L1c, the operating range of the lower parameter increases linearly with the increase of the upper parameter. The operation range of the lower parameters changes in such various modes according to the combination of the types of the upper parameters and the lower parameters. In the example of FIG. 3, the change mode of the operation range of the lower parameter is predetermined, but the user may be able to select the change mode to be used from a plurality of pre-stored change modes. Alternatively, the user may be able to arbitrarily set the change mode.

(5) Sound Effect Control Processing FIGS. 7 and 8 are flowcharts showing an example of the sound effect control processing by the functional units in FIG. The sound effect control process of FIG. 7 is performed when the CPU 11 of FIG. 1 executes the sound effect control program stored in the ROM 10 or the storage device 13.

First, the reference operator setting unit 21 in FIG. 2 sets the operator 7 having the first priority as the “reference operator” (step S1). Next, the acoustic effect information acquisition unit 24 reserves an area in the storage device 13 for temporarily storing the “current parameter value” and the “current range” of each operator 7 (step S2). Next, the CPU 11 determines whether or not an operation for ending the sound effect control process has been detected by the operation detection unit 22 (step S3). The operation for ending is, for example, an operation for setting other than the sound effect. When the operation for ending is detected, the CPU 11 ends the sound effect control process.

When the operation for ending is not detected, the selecting unit 23 determines whether the operation detecting unit 22 detects an operation for selecting the sound effect type (step S4). When the operation for selection is detected, the acoustic effect information acquisition unit 24 acquires acoustic effect information corresponding to the selected acoustic effect type (step S5).

Next, the parameter type acquisition unit 26 acquires the parameter type represented by the acquired acoustic effect information for each operator 7 (step S6). Next, the parameter value determination unit 27 determines whether or not to interlock the acquired plurality of types of acoustic effect parameters, based on the interlocking information of the acquired acoustic effect information (step S7). When a plurality of types of sound effect parameters are not linked, the parameter value determination unit 27 determines, based on the reference range represented by the acquired sound effect information and the state of each operator 7 detected by the operation detection unit 22, A parameter value corresponding to each operator 7 is calculated (step S8). In this case, the operation range of the sound effect parameter corresponding to each operator 7 is set to the reference range represented by the sound effect information. Next, the parameter output unit 28 outputs the acquired parameter type and the calculated parameter value as acoustic effect data (step S9).

When a plurality of types of sound effect parameters are interlocked in step S7, the reference operator setting unit 21 and the parameter value determination unit 27 perform a parameter update process (step S10), and the “current parameter value” stored in the storage device 13 is stored. And "Current Range" are updated. Details of the parameter update processing will be described later. Next, the parameter output unit 28 outputs the acquired parameter type and the updated "current parameter value" as acoustic effect data (step S11).

When the operation for selecting the sound effect type is not detected in step S4, when step S9 is executed, or when step S11 is executed, the CPU 11 detects the operation of one of the operating elements 7 as an operation. It is determined whether or not it is detected by the unit 22 (step S12 in FIG. 8). When the operation of any of the operators 7 is not detected, the CPU 11 returns to step S3. When the operation of any one of the operators 7 is detected, the parameter value determination unit 27 determines whether to interlock a plurality of types of acoustic effect parameters based on the interlocking information of the acquired acoustic effect information. (Step S13).

When step S9 or step S11 is executed, the determination of step S13 is performed based on the acoustic effect information acquired in step S5. On the other hand, immediately after the start of the sound effect control process, and when the operation for selecting the sound effect type is not selected in step S4, the determination in step S13 is made based on the sound effect information acquired in advance. Is done. For example, at the start of the sound effect control process, the sound effect information corresponding to the default sound effect type, or the sound effect information corresponding to the sound effect type selected at the end of the previous sound effect control process is acquired. The determination in step S13 is performed based on the sound effect information.

When a plurality of types of sound effect parameters are not linked, the parameter value determination unit 27 determines the parameter value corresponding to each operator 7 based on the reference range and the state of each operator 7, as in step S8 of FIG. Calculate (step S14). Next, the parameter output unit 28 outputs the parameter type acquired in step S6 and the parameter value calculated in step S14 as acoustic effect data (step S15), and returns to step S3 in FIG. 7.

If you are integrating a plurality of types of sound effects parameters in step S13, the reference operator setting unit 21 sets the operating element 7 which operation is detected in the "reference operator" (step S 16). Next, the reference manipulator setting unit 21 and the parameter value determination unit 27 perform a parameter updating process described later (step S17) to update the "current parameter value" and the "current range" stored in the storage device 13. To do. Next, the parameter output unit 28 outputs the parameter type acquired in step S6 and the updated “current parameter value” as acoustic effect data (step S18), and returns to step S3 in FIG. 7.

The parameter updating process of step S10 of FIG. 7 and step S17 of FIG. 8 will be described. FIG. 9 is a flowchart showing an example of the parameter updating process. First, the parameter value determination unit 27 calculates the parameter value corresponding to the “reference operator” based on the states of the “current range” and the “reference operator” corresponding to the “reference operator” (step S21). ). At the start of the parameter updating process in step S10, the “reference operator” is the operator 7 having the first priority, and the “current range” is the reference corresponding to the operator 7 having the first priority. It is a range. At the start of the parameter updating process in step S17, the "reference operator" is the operator 7 whose operation was detected in the immediately preceding step S12, and the "current range" was updated in the previous parameter updating process. The operating range. The method for calculating the parameter value is the same as the method for calculating the parameter value in step S8 of FIG. 7 and step S14 of FIG. 8 except that the “current range” is used instead of the reference range.

Next, the parameter value determination unit 27 updates the "current parameter value" corresponding to the "reference operator" to the parameter value calculated in step S21 (step S22). Next, the parameter value determination unit 27 determines whether or not the priority of the “reference operator” is the lowest (step S23). When the priority of the “reference operator” is not the lowest, the parameter value determination unit 27 determines the “current parameter value” corresponding to the “reference operator” and the operation range represented by the acquired sound effect information. The operating range of the operator 7 (hereinafter, referred to as "lower operator") whose priority is one lower than that of the "reference operator" is calculated based on the change mode (step S24). In this case, the sound effect parameter corresponding to the “reference operator” corresponds to the upper parameter, and the sound effect parameter corresponding to the “lower operator” corresponds to the lower parameter. In step S24, as in the example of FIGS. 4 and 5, the operation range of the lower parameter is determined based on the value of the upper parameter.

Next, the parameter value determination unit 27 updates the "current range" corresponding to the "lower operator" to the operation range calculated in step S24 (step S25). Next, the parameter value determination unit 27, based on the states of the “current range” and the “lower operator” corresponding to the “lower operator”, the parameter corresponding to the “lower operator” as in step S21. A value is calculated (step S26).

Next, the parameter value determination unit 27 updates the “current parameter value” corresponding to the “lower operator” to the parameter value calculated in step S26 (step S27). Next, the reference operator setting unit 21 sets the "lower operator" to the "reference operator" (step S28), and returns to step S23.

When the priority of the "reference operator" is the lowest in step S23, the reference operator setting unit 21 sets the operator 7 having the first priority as the "reference operator" (step S29). The process ends.

In this way, the plurality of operators 7 are sequentially set as the “reference operators” according to the priority order, and the “current range” and “current parameter value” of the “reference operators” are sequentially updated. In step S10 of FIG. 7, since the operator 7 having the first priority is first set to the “reference operator”, the “current range” and “current parameter value” of all the operators 7 are set. Will be updated. In step S17 of FIG. 8, since the operator 7 in which the operation has been detected is first set as the “reference operator”, the operator 7 in which the operation has been detected and the operator 7 having a lower priority than that. The "current range" and "current parameter value" are updated.

(6) Effects In the acoustic effect control device 100 according to the present embodiment, one of the operators 7 is set as the reference operator, and the priority order is given to the reference operator based on the parameter value of the reference operator. The operating range of the manipulator 7 (lower manipulator) having a low value is determined. As a result, when the lower operator is operated, the parameter value corresponding to the lower operator changes only within an appropriate range depending on the parameter value corresponding to the reference operator. Therefore, the relationship between the parameter value corresponding to the reference manipulator and the parameter value corresponding to the lower manipulator is appropriately maintained. In this way, by appropriately maintaining the relationship between the parameter values of the plurality of operators 7, it is possible to prevent a change in sound such as noise that is not intended by the user. Therefore, the user can appropriately control the acoustic effect without causing any discomfort in hearing with a simple operation without requiring special knowledge.

Further, the parameter value corresponding to the lower-order manipulator is determined based on the operation range of the lower-order manipulator and the state of the lower-order manipulator. Thereby, the user can arbitrarily adjust the parameter value corresponding to the lower-order manipulator by operating the lower-order manipulator within an appropriate operation range depending on the parameter value corresponding to the reference manipulator.

Further, in the present embodiment, acoustic effect information corresponding to the selected acoustic effect type is acquired, and it is determined whether or not a plurality of types of acoustic effect parameters are to be linked based on the acoustic effect information. In this case, for the sound effect type in which it is difficult for the user not to change the sound, the sound effect parameters are controlled independently by adjusting each sound effect parameter independently without linking a plurality of kinds of sound effect parameters. can do. As described above, various acoustic effects can be appropriately controlled by switching whether or not the acoustic effect parameters are interlocked according to the acoustic effect type.

However, the present invention is not limited to this. The target sound effect type may be fixed in advance to one, and the sound effect parameter assigned to each operator may be fixed in advance to one.

(B) In the above embodiment, the operation range of the operator 7 whose priority is one lower than that of the operator 7 is determined based on the parameter value corresponding to the one operator 7, but the present invention is not limited to this.

For example, both the operating range of the parameter B and the operating range of the parameter C may be determined based on the value of the parameter A in FIG. Further, among the plurality of operators 7, only the sound effect parameters corresponding to some of the operators 7 may be linked, and the sound effect parameters corresponding to the other operators 7 may be arbitrarily adjustable. For example, the operation range of the parameter B depends on the value of the parameter A, but the operation range of the parameter C does not depend on either of the parameters A and B and may be fixed to a fixed range (for example, a reference range).

(C) In the above-described embodiment, the operation range of the sound effect parameter having the highest priority and the operation range of the sound effect parameter that is not the target of interlocking are set to the reference range represented by the sound effect information. The upper limit value and the lower limit value of these operation ranges may be settable.

(D) Each operator 7 is not limited to a rotary encoder, but may be a linear encoder that is slid, an image displayed on a touch panel display, or a combination thereof. Moreover, the number of the operators 7 is not limited to three, and two or four or more operators 7 may be provided.
