Remarks
A key describing for selecting the DRC effect type for MPEG-D DRC. The supported values are defined in ISO/IEC 23003-4:2015 and are described as follows: <table> <tr><th>Value</th><th>Effect</th></tr> <tr><th>-1</th><th>Off</th></tr> <tr><th>0</th><th>None</th></tr> <tr><th>1</th><th>Late night</th></tr> <tr><th>2</th><th>Noisy environment</th></tr> <tr><th>3</th><th>Limited playback range</th></tr> <tr><th>4</th><th>Low playback level</th></tr> <tr><th>5</th><th>Dialog enhancement</th></tr> <tr><th>6</th><th>General compression</th></tr> </table>
The value -1 (Off) disables DRC processing, while loudness normalization may still be active and dependent on #KEY_AAC_DRC_TARGET_REFERENCE_LEVEL.<br> The value 0 (None) automatically enables DRC processing if necessary to prevent signal clipping<br> The value 6 (General compression) can be used for enabling MPEG-D DRC without particular DRC effect type request.<br> The default DRC effect type is 3 ("Limited playback range") on mobile devices.
This key is only used during decoding.
