ABSTRACT:
An audio signal recording compensation apparatus enhances a frequency characteristic and prevents saturation of a recording signal by controlling the level of the recording signal when an audio signal is recorded. The audio signal recording compensation apparatus includes a high-pass filter (32) for passing only a high-frequency component of a recording signal. A clipper (34) generates a clipped signal by cutting off the high-pass filtered recording signal beyond predetermined amplitude levels. An adder (36) generates a compensation recording signal by superimposing the clipped signal and the recording signal. In the apparatus, a high frequency component is emphasized without distortion of the recording signal by controlling the level of the high frequency components of the recording signal, thereby improving the frequency characteristic.
