Abstract:
1. A sound recording/reproducing method in a sound recording/reproducing apparatus for recording sound data onto a recording medium and reproducing said sound data from said recording medium, the method comprising: an attribute information recording step of recording, onto said recording medium, attribute information on sound data of a music piece that are to be recorded onto said recording medium; a rule table creation step of creating a rule table that associates the attribute information and digital signal processor (DSP) program parameters, each of the digital signal processor (DSP) program parameters being previously stored in the sound recording/reproducing apparatus and designating a sound field process or a frequency characteristic process, the sound field process or the frequency characteristic process to be performed on a digital signal processor in a connected amplifier apparatus; a DSP program parameter acquisition step of, at a time of reproduction when sound data of a music piece to be reproduced, read out from said recording medium, are to be outputted to said amplifier apparatus that is currently connected to said sound recording/reproducing apparatus, acquiring, from said recording medium, the attribute information on the sound data of the music piece to be reproduced and acquiring, from said rule table, any of the DSP program parameters that corresponds to the attribute information; a step of using, when a model of an amplifier apparatus that is the object of control during creation of said rule table and a model of said amplifier apparatus that is currently connected to said sound recording/reproducing apparatus coincide with each other, said DSP program parameter acquired from said rule table as a DSP program parameter after completion of the acquisition process; a step of using, when the model of an amplifier apparatus that is the object of control during creation of said rule table differs from the model of said amplifier apparatus that is currently connected to said sound recording/reproducing apparatus, a DSP program parameter acquired from said rule table and a DSP program parameter corresponding to said amplifier apparatus that is currently connected to said sound recording/reproducing apparatus from a DSP program associating table that associates DSP program parameters of a plurality of amplifier apparatuses, and using said DSP program parameter acquired from said DSP program associating table as a DSP program parameter after completion of the acquisition process; and a DSP program parameter setting step of setting the DSP program parameter, after completion of the acquisition step, in said digital signal processor of said amplifier apparatus that is currently connected to said sound recording/reproducing apparatus.
