In units of milliseconds. Increasing the value of <CODE>m_DelayTime</CODE> increases the time by which echoes are delayed. In addition, when you increase the size of <CODE>m_DelayTime</CODE>, you need to increase the size of memory that can be obtained by the <CODE><a href="../../../../../nn/snd/CTR/FxDelay/GetRequiredMemSize.html">GetRequiredMemSize</a></CODE> function. The initial value is 250.</p><p><CODE>m_FeedbackGain</CODE> expresses the feedback gain for the delay sound. It needs to be set in range from 0.0f to 1.0f. Increasing the value of <CODE>m_FeedbackGain</CODE> prevents the delay sound from vanishing. Specifying a value of 0.0f (no feedback) indicates a one-shot delay. This value is initially 0.4f.</p><p>The value of <CODE>m_Damping</CODE> affects the behavior of low-pass filters. It needs to be set in range from 0.0f to 1.0f. Increasing this value decreases the cutoff frequency. If you specify a value of <CODE>0.0f</CODE>, a low-pass filter is not applied. This value is initially 0.5f.</p><p>When <CODE>m_IsEnableSurround</CODE> is <CODE>true</CODE>, the surround components (rear left and right) are also delayed. When <CODE>false</CODE>, delay processing is skipped for the surround components and that processing load is decreased. On the other hand, when <CODE>true</CODE>, the processing load increases, and the amount of needed memory to be obtained from the <CODE><a href="../../../../../nn/snd/CTR/FxDelay/GetRequiredMemSize.html">GetRequiredMemSize</a></CODE> function increases.</p><p>When you change <CODE>m_DelayTime</CODE> while an effect is executing, there is the possibility that noise will occur.</p><p>In addition, if you continually change m_FeedbackGain and m_Damping even while an effect is executing, noise will not occur.</p><p>To change a parameter while an effect is executing, call the <CODE><a href="../../../../../nn/snd/CTR/FxDelay/SetParam.html">SetParam</a></CODE> function.</p><!-- write here --></div> 68 <a name="variable" id="variable"> 69<h2>Member Variables</h2> 70 <div class="section"> 71 <table class="members"> 72 <tr> 73 <td width="100"> </td> 74 <th> 75<span class="argument"><CODE>m_DelayTime</CODE></span> 76 </th> 77<td>The delay time (in milliseconds).
