36<H2>Description</H2>
37<P>The <code>AXARTSet3DDopplerScale</code> function sets an arbitrary closing speed scale for the Doppler pitch of 3D sounds. The AXART library finds the pitch for the Doppler Effect using the following formula when a sound source approaches the camera. The scale set by this function is assigned to <code>scale</code> in the formula, while the <code>AXART_3D</code> articulator member <code>closingSpeed</code> is assigned to <code>closingSpeed</code>. Calculation results are saved in the same <code>AXART_3D</code> articulator's member <code>pitch</code>.</P>
