 // (***) !!! REVISIT!!! FL: THD 192 kHz "fudge factor" for CB PCM buffer size.
-// Using this factor in PCM buffer size definition, buffer large enough to execute 96/192 kHz w/o CB OVR/UND.
-// Need to define CB size in different terms than existing macros, e.g. eliminate usage of ASP_DECOP_CB_MAX_NUM_PCM_FRAMES,
-// increase size of ASP_DECOP_CB_MAX_PCM_FRAME_LEN for worst case THD decoder output frame size in 20 msec.
