Description

The ACX_MICROPHONE_COORDINATES structure specifies the 3D location of the microphone in X, Y, and Z coordinates.

Members

Type

A value from the ACX_MICROPHONE_TYPE enum that identifies the pickup pattern of the microphone.

XCoord

The X coordinate of the microphone, in millimeters. Acceptable values range from -32768 to 32767, inclusive.

YCoord

The Y coordinate of the microphone, in millimeters. Acceptable values range from -32768 to 32767, inclusive.

ZCoord

The Z coordinate of the microphone, in millimeters. Acceptable values range from -32768 to 32767, inclusive.

VerticalAngle

Specifies a value between -15708 and +15708. When divided by 10,000, it gives a radian angle measurement.

HorizontalAngle

Specifies a value between -31416 and +31416. When divided by 10,000, it gives a radian angle measurement.

Remarks
