SOUND SIGNAL PROCESSING APPARATUS, MICROPHONE APPARATUS, SOUND SIGNAL PROCESSING METHOD, AND PROGRAM
First Claim
1. 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.

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.
