摘要 |
An apparatus for transforming an input signal having a time length L into an output signal having a time length alpha L in accordance with a given time-scale modification ratio alpha , including a correlator for calculating a value of a correlation function between a first signal and a second signal having a time length T and for determining a time delay Tc at which the value of the correlation function becomes the greatest; an adder for adding the first signal multiplied by a first window function to the second signal multiplied by a second window function with a displacement of the time delay Tc; and an outputting circuit for selectively outputting the output of the adder and a third signal succeeding the output of the adder so that the sum of a time length of the output of the adder and a time length of the third signal is substantially equal to a time length defined by the time-scale modification ratio alpha , the time delay Tc and the time length T. <IMAGE> |
