EAX_ECHO

The structure EAX_ECHO used to control the echo filter in the EAX 4 3D provider

struct EAX_ECHO
{
  S32 Slot;
  S32 Volume;
  F32 Delay;
  F32 LRDelay;
  F32 Damping;
  F32 Feedback;
  F32 Spread;
};

Slot: specifies the slot to query or set. Echo can use slot 2 and/or 3.
Volume: specifies the volume of this slot in standard EAX attenuation units (-10000 to 0 fixed point millibels, default 0.0).
Delay: specifies the initial delay time in seconds (0.002 to 0.207, default 0.1).
LRDelay: specifies the delay time between the first and second taps in seconds (0.002 to 0.404, default 0.1).
Damping: controls a low-pass filter that dampens the echoes (0.0 to 0.99, default 0.5).
Feedback: controls the duration of echo repetition (0.0 to 1.0, default 0.5).
Spread: controls the left-right spread of the echoes (-1.0 to 1.0, default -1.0).

See the EAX 4 documentation for technical details on this filter.
