30<h2>Description</h2>
31
32<p>The <CODE>MIXUpdateSettings</CODE> function generates new internal mixing values and updates AX with them. The <CODE>MIXUpdateSettings</CODE> function can run with interrupts enabled. This function must be invoked by the audio frame callback routine, which in turn must be registered by the <CODE>AXRegisterCallback</CODE> function. For example:</p>
33<BLOCKQUOTE><PRE><CODE>static void callbackForAudioFrame(void)
34{
35　　...
36　　// tell the mixer to update settings to AX
37　　MIXUpdateSettings();
38}
39
40void main(void)
41{
42　　...
43
44　　AXInit();
45　　MIXInit();
46　　AXRegisterCallback(&amp;callbackAudioFrame);
47
48　　...
49
50　　MIXQuit();
51　　AXQuit();
52　　...
53}</CODE></PRE></BLOCKQUOTE>
