 See Open AL Specifications (available to download on Open AL web site) for detailed information on the various kind of attenuation.
“Orientation”. Orientation control is a pair of 3-tuples consisting of an ‘at’ vector and an ‘up’ vector, where the ‘at’ vector represents the ‘forward’ direction of the listener and the orthogonal projection of the ‘up’ vector into the subspace perpendicular to the ‘at’ vector represents the ‘up’ direction for the listener. OpenAL expects two vectors that are linearly independent. These vectors are not expected to be normalized. If the two vectors are linearly dependent, behavior is undefined.
“Edit/Lock”. Click and drag this slider to freeze all global settings or to enable the settings’ editing.
“Doppler Factor”. This slider is a simple scaling of source and listener velocities to exaggerate or de-emphasize the Doppler (pitch) shift resulting from the calculation. The Doppler effect depends on the velocities of source and listener relative to the medium, and the propagation speed of sound in that medium. You might want to emphasize or de-emphasize the Doppler effect as physically accurate calculation might not give the desired results. The amount of frequency shift (pitch change) is proportional to the speed of listener and source along their line of sight.
“Speed of Sound”. Changes the reference (propagation) speed used in the Doppler calculation. The default speed of sound value is 343.3.
“Velocity (Listener Vector)”. The OpenAL listener object and source objects have attributes to describe their position, velocity and orientation in three dimensional space. OpenAL -- like OpenGL -- uses a right-handed Cartesian coordinate system (RHS), where in a frontal default view X (thumb) points right, Y (index finger) points up, and Z (middle finger) points towards the viewer/camera. “Velocity (Listener Vector)” value is taken into account by the driver to synthesize the Doppler effect perceived by the listener for each source, based on the velocity of both source and listener, and the Doppler related parameters.
