Title:
可変速度で再生可能なテストサウンド信号と基準サウンド信号との間の相関を実行するための装置および方法
Document Type and Number:
Japanese Patent JP5137827
Kind Code:
B2
Abstract:
An apparatus for performing a correlation between a test sound signal replayable at variable speed and a reference sound signal, which is a digitally stored version of the test sound signal, has a determinator for determining a measure for the replay speed of a test sound signal; a variator for varying a test sound signal sampling rate, to generate a modified test sound signal depending on the measure for the replay speed, or for varying a reference sound signal sampling rate, to generate a modified reference sound signal depending on the measure for the replay speed, the variator being formed to vary the test or reference sampling rate so that a deviation between a test or modified test sound signal replay speed and a reference or modified reference sound signal replay speed is reduced; and a comparator for comparing the test or modified test sound signal and the reference or modified reference sound signal to obtain a correlation result.
