Audio Processors IC

Audio processors IC are semiconductor devices used to detect, decode and process analog or digital video. Basic functions for these integrated circuits (ICs) include multi-channel input selection, treble and bass controls, and left-right or balance controls. Audio processors IC may also provide bus-controlled volume, tone and balance controls, a surround sound matrix, and a voice-cancelling function. By loading commands from a serial bus, the surround sound matrix can use phase shifters to create music, movie, and simulated stereo effects. By loading an internal eight-bit control register, audio processors IC can be programmed to provide hundreds of different arrangements for each effect. Audio processing products that use a combination of bipolar and complementary metal-oxide semiconductor (CMOS) technologies can reduce noise, distortion, and the decibel (dB) level of volume and tone steps.
