AXART_VOLUME_ENV is a data structure used to describe a volume envelope sound articulator. This articulator will apply a volume attenuation delta for an AXART_SOUND until the volume attenuation reaches the target. Prior to calling AXARTAddArticulator() for the AXART_VOLUME_ENV, the user application must call AXARTInitArtVolumeEnv().
| Data Member | Description |
| AXART_ART art | AXART articulator descriptor maintained by AXART. Do not write to this parameter. |
| s32 delta | Volume attenuation delta per audio frame (0x00010000 = 0.1 dB). |
| s32 target | Volume attenuation target (0x00010000 = 0.1 dB). |
| s32 attenuation | Current envelope output. |
