39<h2>Description</h2>
40    <div class="section">
41<p>Sets the interpolation method of a voice.</p><p>Specify a value from the <CODE>nn::snd::CTR::InterpolationType</CODE> enumerated type.
42      </p><p>
43The default value is <CODE>INTERPOLATION_TYPE_POLYPHASE</CODE>.
44</p><p><b>Bug:</b> Using <CODE>INTERPOLATION_TYPE_LINEAR</CODE> can cause noise. Sound sources that match the following may be noisy.
45        <ul><li>
46Adjacent 16-bit PCM samples differ by 32768 or more.
47          </li></ul>
48This would apply to -6dB pulse waveforms, for instance. Do not use <CODE>INTERPOLATION_TYPE_LINEAR</CODE> for sound sources that match the above. Noise does not occur with sound sources that do not include high-frequency components and sound sources with 16-bit PCM amplitudes under 16384.
49      </p><p>
50This bug should be fixed in CTR-SDK 0.16.
