Abstract :
A microcomputer-controlled HI-FI audioprocessor with input selector, and base treble, volume, and fader control is described. This audioprocessor satisfies all necessary requirements for audiosignal processing of microcomputer-controlled car radios. The flexible concept allows further application in microcomputer-controlled HI-FI receivers with monitor and loudness function. The excellent distortion of 0.01%, a signal-to-noise ratio of 96 dB, and a high crosstalk attenuation higher than 90 dB qualifies this IC for high-end audio applications
