Abstract

There is provided a signal processing apparatus including a provision control unit that provides choices expressed subjectively and associated with control for an acoustic signal, and an output unit that outputs a predetermined choice selected from the provided choices.

Claims

1. A signal processing apparatus comprising:

a provision control unit that provides choices expressed subjectively and associated with control for an acoustic signal; and

an output unit that outputs a predetermined choice selected from the provided choices.

2. The signal processing apparatus according to claim 1,

wherein the provision control unit changes a display aspect of the provided choices, according to the selected choice or a feature amount of an acoustic signal of a processing object.

3. The signal processing apparatus according to claim 1,

wherein the provided choices are subjective senses and/or subjective requests to be handled.

4. The signal processing apparatus according to claim 1, further comprising:

a calculating unit that calculates an adjustment parameter to adjust an acoustic signal of a processing object, based on individual parameters measured in advance, the selected predetermined choice, and a feature amount of the acoustic signal of the processing object.

5. The signal processing apparatus according to claim 4,

wherein the individual parameters are parameters showing aural characteristics.

6. The signal processing apparatus according to claim 4,

wherein the individual parameters are parameters showing characteristics of a microphone and/or a speaker.

7. A signal processing method comprising:

providing choices expressed subjectively and associated with control for an acoustic signal; and

outputting a predetermined choice selected from the provided choices.

8. A signal processing apparatus comprising:

an acquiring unit that acquires an adjustment parameter calculated based on individual parameters measured in advance, a predetermined choice selected from choices expressed subjectively and associated with control for a provided acoustic signal, and a feature amount of an acoustic signal of a processing object; and

a signal processing unit that adjusts the acoustic signal of the processing object, based on the acquired adjustment parameter.

9. The signal processing apparatus according to claim 8,

wherein the signal processing unit has a first buffer and a second buffer that accumulate the adjustment parameter, and

wherein, when the adjustment parameter is acquired by the acquiring unit in a use state of the adjustment parameter accumulated in one buffer, the signal processing unit accumulates the acquired adjustment parameter in another buffer and then switches the use state into a use state of the adjustment parameter accumulated in the another buffer.

10. The signal processing apparatus according to claim 8,

wherein the signal processing unit has a buffer that accumulates the adjustment parameter, and

wherein, when the adjustment parameter is acquired by the acquiring unit in a use state of the adjustment parameter accumulated in the buffer, the signal processing unit mutes an output of the adjusted acoustic signal, accumulates the acquired adjustment parameter in the buffer, and then releases muting.

11. The signal processing apparatus according to claim 8, further comprising:

an analyzing unit that analyzes the acoustic signal of the processing object and calculates a feature amount of the acoustic signal.

12. The signal processing apparatus according to claim 8, further comprising:

a calculating unit that calculates the adjustment parameter.

13. A signal processing method comprising:

acquiring an adjustment parameter calculated based on individual parameters measured in advance, a predetermined choice selected from choices expressed subjectively and associated with control for a provided acoustic signal, and a feature amount of an acoustic signal of a processing object; and

adjusting the acoustic signal of the processing object, based on the acquired adjustment parameter.
