5.3 Audio Manager in DSP Composer Environment
All configuration information described in Section 5.2 can be controlled in DSP Composer. The Audio Manager is included
with the (SPP) Standard Post Processing Overlay as well as the (APP) Advanced Post Processing Overlay Post
Processing Modules. To insert the Audio Manager, drag the Post Processing Modules folder to the workspace and select
either SPP or APP. Once the SPP or APP Module is on the workspace, the runtime controls for Audio Manager can be
accessed by double-clicking the SPP or APP Module. The runtime control for the Audio Manager Module is shown in
Fig. 5-1 , for Remap for the cs48520 in Fig. 5-2 , and Remap for the cs48540 in Fig. 5-3 . Remap is part of Audio Manager,
but has been separated into the system block to centralize channel mapping controls. The controls are adjustable during
runtime to interact with the DSP in a similar way as would a host-microcontroller in an actual system.
