Delay finder setup options
Sets the maximum delay that can be computed. The default is 1 second, which equates to a maximum distance between microphone and speakers of roughly 300 meters, and should be large enough for most practical applications. You can decrease this value as this minimizes the possibility of false readings.
Selects between three different delay finding algorithms:
In the rare case where the standard method fails in your particular environment, you should try other methods.
The delay can be set to work in one or two passes:
Two-stage delay finding can improve accuracy in the context of an environment with heavy multiple reflections.
