記録するようにしている。For example, a signal obtained by doubling a signal between 15 kHz and 20 kHz is superimposed, and in periods T1c and T1d, an ultra-treble amplified modified signal (B), for example, a 15 kHz signal, is amplified twice on the original audio signal, The signal is superimposed with the magnification set to 4 times as high as the frequency of 20 kHz by gradually increasing the magnification. This superimposed and generated modified new audio signal is recorded on a modified new tape 85 by a modified new audio recorder 83.
