PURPOSE:To use a DSP so as to implement properly surround processing, creation of a sound field and its correction picture. CONSTITUTION:The equipment is provided with 1st-3rd DSPs and a A/D converter. The 1st DSP implements generation of a test tone signal, adjustment of balancing levels of plural digital audio signals, and correction of a dynamic range. The 2nd DSP applies decode processing for surround stereo reproduction to an output signal of the 1st DSP to output a digital surround signal. The 3rd DSP applies sound field creation or correction processing to an output signal of the 2nd DSP. The D/A converter converts the output signal of the 3rd DSP into an analog audio signal, which is outputted. |
