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>
