45    <h2>Description</h2>
46    <div class="section">
47      <p>Changes the surround pan (front-back position) of a track in a stream sound.</p><p>Changes the surround pan of a stream track in the sound associated with the handle. If the handle is invalid, the function does nothing.</p><p>The value specified by this function operates independently of other surround pan parameters, which are all layered.</p><p>The trackBitFlag argument specifies the track. Tracks are identified from the lower bit in sequence; for example, Track 0, Track 1, Track 2 and so on. The silent status will change for all tracks with enabled bits. For example, to change the silent status of Track 2 and Track 5, use  (1 &lt;&lt; 2) | (1 &lt;&lt; 5); i.e., 0x0024.</p><p>surroundPan specifies a value representing the relative change in the location of the sound. Pitch does not change when 0.0 is specified. If 1.0 is specified, a sound located in the center is relocated to the front. If 2.0 is specified, a sound located in the center is relocated to the back. Specify a negative number if you wish to move the location toward the front. The default value is 0.0.</p></div>
