MSM6722
GENERAL DESCRIPTION
The MSM6722 converts in real-time the pitch of the speech signal in a range of one octave upward
or downward.
Two pitch control methods can be selected. One is to change the pitch in 17 steps by two switch
inputs, and the other is to select one of 16 steps by four binary input lines.
Since a microphone preamplifier and a low-pass filter are built in, the pitch conversion set can
easily be configured by connecting a microphone, amplifier, and speaker in the peripheral
circuit. The MSM6722 is functionally compared to the MSM6322, as described below.
1.Speech pitch step reset (UP/DW mode)
MSM6322 ·············· PRST pin only
MSM6722 ·············· PRST pin and UPC (DWC) pin available.
2.Change in pitch
MSM6322 ·············· Speech pitch is changeable in 17 steps.
