MUTE MODES
Figure 24 Application and Release of Soft Mute
Figure 24 shows the application and release of SOFTMUTE for a full amplitude sinusoid being played
at 48kHz sampling rate. When SOFTMUTE (lower trace) is asserted, the WM8741 output (upper
trace) begins to decay exponentially from the DC level of the last input sample. The output decays
towards V
its previous value.
