Title: Audio device, method of calculating delay time, and recording medium
Inventor: ASADA KOHEI
IPC: H04R3/00
Filed: 2006-04-24
Abstract: An audio device, a method of calculating delay time, and a recording medium are provided to prevent the stress on a memory for storing an impulse response when calculating a time delay. In an audio device, a positive value conversion unit(83) converts a test signal emitted from a speaker into a positive value with respect to a response signal obtained by a microphone. A detection device detects a first transient response part to be the first mountain part of the response signal converted into the positive value by the positive value conversion unit(83). An analogizing device analogizes a rising point of the corresponding response signal from more than N (N is a positive number over 1) points including the peak position or vicinity of the first transient response part and determined in response to the response signal converted into the positive value. A calculating device calculates a time delay of voice collected by the microphone based on the rising point analogized by the analogizing device and a generation timing of the test signal.
