PURPOSE:To easily restore original acoustic space by computing set data to approximate to a desired curve, transferring computed set data to an acoustic correction means, and registering the set data on a storage means CONSTITUTION:The desired curve is set by a key operation by an audio analyzer 5. Thence, a noise for measurement that is a reference audio signal is outputted from the analyzer 5 to a DSP part 2, and a tone from a speaker 4 is fetched in the analyzer 5, then, the frequency characteristic of the tone is analyzed. An analyzer 6 that is a means to compute the set data decides the set data for the network gain of the DSP part 2 and the one for the parameter value of a parametric equalizer based on an analyzed result, and transmits the set data to the DSP part 2. When the set data is preserved, it is recorded on the floppy disk of a data storage part in a personal computer part 7. Acoustic space can be immediately restored by transmitting the set data from the disk to the DSP part 2. |
