Hi Derek, <br><br>they have to be separate. The idea is to control a cursor by sound. <br>Every direction (left, right, up, down) is supposed to be controlled by a different sound source. <br>Currently I am using one microphone and the SpectralAnalyzerMorph. The fft allows me to split up different frequencies. Consequently, by whisteling at specific frequencies one can control the cursor in different directions. <br>
<br>What I have in mind however are different sound sources having the same frequency content. The control of the cursor hence relies on amplitude.<br><br>One possibility would be to record four microphones, externally modulate the frequencies, combine the signals an pull them apart by the fft again. <br>
<br>I was hoping for something more out of the box :). But there apparently is no simple way to solve that problem<br><br>Best<br>Martin<br><br><br><br><br><br><br><br><br><div class="gmail_quote">2009/2/7 Derek O'Connell <span dir="ltr"><<a href="mailto:doconnel@gmail.com">doconnel@gmail.com</a>></span><br>

If they do have to be separate then a better idea of what you want to<br>
do would allow alternative suggestions.<br>
