The HT8972 is an echo/surround effect processor. It is designed for various audio systems including karaoke, television, sound equipments, etc. The chip consists of a built-in pre-amplifier, VCO or Voltage Control OSC, 40Kb SRAM, A/D and D/A converters as well as delay time control logic.
HT8972's built-in 40Kb SRAM can generate delay time effect and can control the delay time value through the external VCO resistor.
The VCO circuit HT8972 can reduce external components and make it easy to adjust the delay time.
