Audio reproduction apparatus having audio modulation function, method used by the apparatus, remixing apparatus using the audio reproduction apparatus, and method used by the remixing apparatus

摘要

An audio reproduction apparatus capable of modulating an audio signal with at least one of reproduction factors, including the speed and direction of reproduction, and the sound pressure of the audio signal, an audio reproduction method used by the audio reproduction apparatus, a remixing apparatus employing the audio reproduction apparatus, and a remixing method used by the remixing apparatus are provided. The audio reproduction apparatus for reproducing a first audio signal recorded in a predetermined first recording medium includes: a reproduction control unit for generating a reproduction control signal by analyzing at least one of first and second displacement values, which are varied by a user, and outputting the generated reproduction control signal; and an audio reproduction unit for modulating and reproducing the first audio signal according to the reproduction control signal. The audio reproduction apparatus can modulate an audio signal in a variety of ways. The structures of the audio reproduction apparatus and the remixing apparatus are simple, and an audio signal can be finely modulated at low cost. Drawbacks which would occur by use of a needle can be eliminated. A digital audio signal of a CD can be efficiently modulated and reproduced without need for remastering into an LP record. A high-resolution digital audio signal can be modulated and reproduced at an accurate sampling rate.
