Audio Processor Block
STV82x6
SRS™ creates a fully immersed three-dimensional soundfield through the use of a standard
2-speaker stereo configuration. For monaural audio, the source is first converted into a synthetic
stereo signal before creating the 3D effect. The virtual gain for the Surround and Center
components can be adjusted by registers LS_SRS_SPACE and LS_SRS_CENTER (respectively)
in Stereo mode only. These values are used to adapt spatial effects to the source.
For ST WideSurround Sound, Stereo or Mono output mode is automatically selected by the
Automatic Standard Recognition System (AUTOSTD) according to the detected audio source. By
default, ST WideSurround Sound is selected. SRS™ Surround is selected in register
LS_SRD_CTRL.
