Determines the operation used to calculate the transmission loss value for a transmission path. A ray is cast from listener to emitter, and this operation is applied to combine the current surface with the previous. A geometry instance can be marked as solid by using AkGeometryInstanceParams::IsSolid. If a geometry instance is solid, transmission loss is applied for each pair of hit surfaces, representing an entrance and exit through the geometry. The transmission loss from a pair of hits through a solid geometry instance will be the max of both hits.
| 枚举值 |
|---|
| AkTransmissionOperation_Add | Transmission loss of each hit surface is summed until it reaches 100%.
|
| AkTransmissionOperation_Multiply | The inverse of transmission loss (1 - TL) is multiplied in succession, and the result inverted. With each hit surface, the effect of additional transmission loss is reduced. The total loss will approach but never reach 100% unless a surface with 100% loss is found.
|
| AkTransmissionOperation_Max | The highest transmission loss of all hit surfaces is used.

| AkTransmissionOperation_Default | |
