摘要
A method of measuring and improving acoustic properties, and a recording medium and a music reproduction apparatus that are suitable for the method. The method includes reproducing and outputting an analysis signal stored in codec file types, recording the output analysis signal in the codec file types, obtaining an impulse response by performing convolution on the recorded signal and an inverse signal of the analysis signal, and correcting frequency properties based on the impulse response. By storing a signal that is supposed to be generated by a signal generation device in codec file types, it is possible to implement the signal in a music reproduction apparatus without a need for the signal generation device. By correcting frequency property, the music reproduction apparatus can improve the performance of an output acoustic signal close to that of an original sound.
