Abstract
Provided is a device 1 including: a signal processing unit 40 that applies a rotary speaker effect corresponding to a rotation speed value to a sound signal and control a tone color of the sound signal; and a control unit 10 that gradually changes, in response to a change command of the rotation speed value, the rotation speed value from a first speed to a second speed higher than the first speed with a first change curve having a first delay, and gradually changes control of the tone color from a first characteristic to a second characteristic that is stronger in the high frequency range than the first characteristic with a second change curve having a second delay shorter than the first delay.
Claims12
A method of controlling an effect applying device for applying a rotary speaker effect corresponding to a rotation speed value to a sound signal and controlling a tone color of the sound signal, the control method comprising:
- receiving a speed change command of the rotation speed value;
- and
- in response to receiving the speed change command:
- gradually changing the rotation speed value from a first speed, which is a current speed before receiving the speed change command, to a second speed higher than the first speed;
- and
- changing the tone color from a first characteristic, which is the characteristic before receiving the speed change command, to a second characteristic that is different in tone color from the first characteristic.
An effect applying device comprising:
- a signal processing unit configured to apply a rotary speaker effect corresponding to a rotation speed value to a sound signal and control a tone color of the sound signal;
- and
- a control unit including a processor configured to, in response to a change command of the rotation speed value:
- gradually change the rotation speed value from a first speed, which is a current speed before receiving the speed change command, to a second speed higher than the first speed;
- and change the tone color from a first characteristic, which is the characteristic before receiving the speed change command, to a second characteristic that is different in tone color from the first characteristic.
An effect applying device comprising:
- a memory storing instructions;
- and
- a processor that implements the instructions to:
- apply a rotary speaker effect corresponding to a rotation speed value to a sound signal and control a tone color of the sound signal;
- and
- in response to a change command of the rotation speed value:
- gradually change the rotation speed value from a first speed, which is a current speed before receiving the speed change command, to a second speed higher than the first speed;
- and
- change the tone color from a first characteristic, which is the characteristic before receiving the speed change command, to a second characteristic that is different in tone color from the first characteristic.
