41<h2>Return Values</h2>
42<div class="section">Returns <CODE>true</CODE> if the data was obtained successfully; otherwise, returns <CODE>false</CODE>. </div>
43<h2>Description</h2>
44    <div class="section">
45<p>Copies the <CODE>Mix</CODE> bus data to the specified buffer.</p><p>
46The data is interleaved and copied to the region that begins at <SPAN class="argument">pData</SPAN>. The <CODE>Mix</CODE> bus data contains 16-bit stereo PCM waveforms, so the length of the data being copied will be <CODE>sizeof(s16) * nSamplesPerFrame * 2</CODE>.
47      </p><p>
48This function has to be called within the sound thread. Use the <CODE><a href="../../../nn/snd/CTR/OutputCapture/Overview.html">nn::snd::CTR::OutputCapture</a></CODE> class when you want to get data asynchronously within the sound thread.
