I'm sure you can think of numerous uses for this command! Use the frequency of your sound as the 'baseline' for pitch change. So if your sample is at 11025 hertz, increase the pitch to 22050 to make the pitch higher, 8000 to make it lower, etc. While similar to <a href='SoundPitch.htm'>SoundPitch</a>, this command let's you change the pitch individually of each and every channel in use.</td></tr></table><p class='header'>Example: <br><br><table width='100%' border='0' cellspacing='2' cellpadding='2' align='center'><tr><td>; Channel examples<br>
