Miles Sound System SDK 7.2a

AIL_set_3D_doppler_factor

The function AIL_set_3D_doppler_factor sets the driver's global 3D Doppler factor.

void AIL_set_3D_doppler_factor(
  HDIGDRIVER driver,
  F32 factor
);

In Parameters

driver: indicates the driver to set.
factor: indicates new Doppler factor to use.

Discussion

The Doppler factor controls the scale of the Doppler effects. The default Doppler scale is 1.0 which means no change to the calculated "real-world" Doppler effect. You can double the Doppler effect by using 2.0, and you can turn off Doppler completely by using 0.0.

Use the AIL_set_sample_3D_velocity and AIL_set_listener_3D_velocity functions to set the velocities of your samples and the listener.
