20    <div class="section">
21      <p>
22      <ul>
23        <li>A Button: Plays the sound while pressed (no Doppler effect or filter applied)</li>
24        <li>X Button: Plays the sound while pressed (no Doppler effect or filter applied)</li>
25        <li>B Button: Resets sound source coordinates</li>
26        <li>L/R Buttons: Selects the filter type</li>
27        <li>+Control pad: Moves the sound source coordinates</li>
28      </ul>

32    <div class="section">
33      <p>
34      The following demos show the techniques required for processing 3D sounds.
35      <ul>
36        <li><a href="../Sound3DManager/Overview.html">nw::snd::Sound3DManager Class</a></li>
37        <li><a href="../Sound3DActor/Overview.html">nw::snd::Sound3DActor Class</a></li>
38        <li><a href="../Sound3DListener/Overview.html">nw::snd::Sound3DListener Class</a></li>
39      </ul>
40      The demo demonstrates the use of the above classes.
41      </p>
42      <p>
43      Use of 3D sounds allows you to apply panning and volume changes suited to the 3D game space.
44      </p>
45      <p>
46        Move along the x-axis using +Control pad Left/Right. This results in a left-right panning motion.<BR> Move along the z-axis using +Control pad Up/Down.
47      </p>
48      <p>
49        A Doppler effect can be applied while playing a sound with the X Button by moving the sound coordinates using the +Control pad. <br>The biquad filter selected using the L/R Buttons is also applied.
