SOFT MUTE AND AUTO-MUTE
w
The WM8608 has a Soft Mute function set by the SMUTE control bit. Figure 21 shows the application
and release of SMUTE while a full amplitude sinusoid is being played at 48kHz sampling rate. When
SMUTE (lower trace) is asserted, the output (upper trace) begins to decay exponentially from the DC
level of the last input sample. The output will decay towards zero with a time constant of
approximately 64 input samples. When SMUTE is turned off, the output will restart almost
immediately from the current input sample, thus possibly causing a pop sound.
This function is disabled by default.
