Fig. 1    AC-3 Code Configured for AC-3
Fig. 1 is a function block diagram of the application code when configured for Dolby Digital. It gives an idea of the
interaction between the various application modules when AC3 is enabled.

8. Sound Field Effect (Hall, Theater)
Fig. 3    Effect Code Block Diagram
Fig. 3 is a function block diagram of the application code when configured for Effect Processing. It gives an idea of
the interaction between the various application modules when the effects are enabled.
9. Bass Management
Fig. 4    Filter Topology
The Bass Manager is best described with the use of a block diagram.
Fig. 4 shows the topology of the filter used for both the low pass and high pass filters. This filter represents two first
order filters cascaded to implement a second order filter. Depending on the coefficient values, either a second order
low pass or second order high pass can be implemented. The default 3dB frequency for this filter is 100Hz. The
corner frequency can be changed by downloading new values for the coefficients a1, b0 and b1.
