+<p>The <code>SDL::AudioCVT</code> is used to convert audio data between different formats. A <code>SDL::AudioCVT</code> structure is created with the

+<p>Before an <code>SDL::AudioCVT</code> structure can be used to convert audio data it must be initialized with source and destination information.</p>
+<p><code>src_format</code> and <code>dst_format</code> are the source and destination format of the conversion. (For information on audio formats see 
+<code>SDL::AudioSpec</code>). <code>src_channels</code> and <code>dst_channels</code> are the number of channels in the source and destination formats. 
+Finally, <code>src_rate</code> and <code>dst_rate</code> are the frequency or samples-per-second of the source and destination formats. Once again, 
+see <code>SDL::AudioSpec</code>.</p>
+<p>Currently (SDL-1.2.11) only rate conversions of 2x and (1/2)x with x &gt; 0 are done, nearing the requested rate conversion. </p>
