1. A control device comprising:
- a conversion unit converting an audio signal collected by a microphone into a pulse signal;
a counting unit counting the number of generated pulses based on the pulse signal;
a counting control unit controlling the counting unit so that pulses generated in a given period starting after one pulse has been generated in the pulse signal are excluded from counting targets of the number of generated pulses; and
a control unit performing given control based on the number of generated pulses.

Abstract
A control device includes: a conversion unit converting an audio signal collected by a microphone into a pulse signal; a counting unit counting the number of generated pulses based on the pulse signal; a counting control unit controlling the counting unit so that pulses generated in a given period starting after one pulse has been generated in the pulse signal are excluded from counting targets of the number of generated pulses; and a control unit performing given control based on the number of generated pulses.

8. A control method comprising the steps of:
-
converting an audio signal collected by a microphone into a pulse signal by a conversion unit; counting the number of generated pulses based on the pulse signal by a counting unit; controlling the counting unit by a counting control unit so that pulses generated in a given period starting after one pulse has been generated in the pulse signal are excluded from counting targets of the number of generated pulses; and performing given control based on the number of generated pulses by a control unit.

9. A control program for allowing a computer to executes the steps of:
-
converting an audio signal collected by a microphone into a pulse signal by a conversion unit; counting the number of generated pulses based on the pulse signal by a counting unit; controlling the counting unit by a counting control unit so that pulses generated in a given period starting after one pulse has been generated in the pulse signal are excluded from counting targets of the number of generated pulse; and performing given control based on the number of generated pulses by a control unit.
