Abstract
A sound signal processing apparatus includes a sliding operation detecting section to which a sound signal collected by a microphone is inputted, and which determines start and end of a sliding operation by a determination process using a sliding sound signal component in the inputted sound signal, the sliding sound signal component being produced by the sliding operation on the microphone itself or its vicinity, and a control section that performs a predetermined control process that is set with respect to the sliding operation, during a period from the start to the end of the sliding operation determined by the sliding operation detecting section.
Claims13
A sound signal processing apparatus comprising:
- a sliding operation detecting section to which a sound signal collected by a microphone is inputted, and which determines start and end of a sliding operation on the microphone itself or its vicinity by a determination process using the inputted sound signal;
- and
- a control section that performs a predetermined control process that is set with respect to the sliding operation, during a period from the start to the end of the sliding operation determined by the sliding operation detecting section;
- wherein as the determination process, the sliding operation detecting section determines that the sliding operation has been started, when a time during which an energy level of the inputted sound signal is equal to or higher than a first level has continued for a first time or more;
- and
- wherein as the determination process, the sliding operation detecting section determines that the sliding operation has been ended, when a time during which the energy level of the inputted sound signal is lower than a second level has continued for a second time or more.
A microphone apparatus comprising:
- a microphone;
- and
- a sliding guide section that is formed in a vicinity of the microphone and guides a sliding operation position.
A microphone apparatus comprising:
- a microphone;
- and
- a directional sound source section that is provided in a vicinity of the microphone, and produces different sound signal components depending on a sliding operation direction.
A microphone apparatus comprising:
- a microphone;
- and
- a plurality of sliding sound source sections that are provided in a vicinity of the microphone, and produce different sound signal components when a sliding operation is performed.
A sound signal processing method comprising:
- determining start and end of a sliding operation on a microphone itself or its vicinity by a determining process using a sound signal collected by the microphone;
- and
- performing a predetermined control process that is set with respect to the sliding operation, during a period from the determined start to end of the sliding operation.
A program for causing an arithmetic processing apparatus to execute:
- determining start and end of a sliding operation on a microphone itself or its vicinity by a determining process in a sound signal collected by the microphone;
- and
- performing a predetermined control process that is set with respect to the sliding operation, during a period from the determined start to end of the sliding operation.
