Abstract

[Object] To provide a signal processing apparatus that can perform presentation so that a body motion itself can be aurally felt. [Solution] There is provided a signal processing apparatus including: a control unit configured to execute, on a basis of a waveform signal generated in accordance with a motion of an attachment portion of a sensor attached to a tool or a body, effect processing for the waveform signal or another waveform signal, the waveform signal being output from the sensor. It is possible for the signal processing apparatus to perform presentation so that a body motion itself can be aurally felt can be provided.

First claim

1 . A signal processing apparatus comprising:
a control unit configured to execute, on a basis of a waveform signal generated in accordance with a motion of an attachment portion of a sensor attached to a tool or a body, effect processing for the waveform signal or another waveform signal, the waveform signal being output from the sensor.

2 . The signal processing apparatus according to claim 1 , wherein the waveform signal is a sound signal collected by the sensor.

3 . The signal processing apparatus according to claim 1 , wherein, in a case where the waveform signal is not a sound signal, the control unit converts the waveform signal into a sound signal, and then executes the effect processing.

4 . The signal processing apparatus according to claim 1 , wherein the waveform signal is a signal that is based on a motion amount detected by the sensor.

5 . The signal processing apparatus according to claim 1 , wherein the control unit executes effect processing that is based on the waveform signal, on a signal obtained by synthesizing a sound signal from a predetermined sound source, and the another waveform signal.

6 . The signal processing apparatus according to claim 1 , wherein the control unit synthesizes the waveform signal and the another waveform signal that are obtained after effect processing.

7 . The signal processing apparatus according to claim 1 , wherein the control unit executes, as the effect processing, processing including amplification processing for at least a partial frequency band.

8 . The signal processing apparatus according to claim 1 , wherein the control unit executes, as the effect processing, processing including echo processing for at least a partial frequency band.

9 . The signal processing apparatus according to claim 1 , wherein the control unit executes, as the effect processing, processing including pitch shift processing.

10 . The signal processing apparatus according to claim 1 , wherein the control unit changes a detail of the effect processing in accordance with content of the waveform signal.

11 . The signal processing apparatus according to claim 1 , wherein the control unit changes a detail of the effect processing in accordance with an instruction issued by a user.

12 . The signal processing apparatus according to claim 1 , comprising:
a semispherical case having honeycomb holes, the semispherical case covering a sensor that outputs the waveform signal.

13 . The signal processing apparatus according to claim 12 , wherein the holes of the case become smaller toward a center.

14 . A signal processing method comprising:
executing, by a processor, on a basis of a waveform signal generated in accordance with a motion of an attachment portion of a sensor attached to a tool or a body, effect processing for the waveform signal or another waveform signal, the waveform signal being output from the sensor.

15 . A computer program for causing a computer to execute:
executing, on a basis of a waveform signal generated in accordance with a motion of an attachment portion of a sensor attached to a tool or a body, effect processing for the waveform signal or another waveform signal, the waveform signal being output from the sensor.
