</div>I suggest you do some experiments before you give a talk. At 4 Hz you<br>
won't be able to hear anything, you won't even be able to reproduce a<br>
4 Hz sound with common speakers.<br></blockquote><div><br>You took me quite literally, [I did put the vibrate into quotes :-) ]<br>Let me spell out the experiment in more detail:<br>Say I have a rhythm in 4/4 time -- 4 even quarter notes, bar repeating every second played by say a click. [What kind of click I am not very sure; sharp with few harmonics would be best I expect]<br>
Now if there were some (realtime) way of sliding the tempo from 1 sec to millisec I expect the separate clicks would vanish into a hum at some stage.<br><br>This (and other such experiments) is what I want to demo.<br>Ive started looking at chuck.<br>
How does it compare with puredata?<br><br><br></div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

<br>
</div>puredata springs to mind, it's easy to use and has everything you need.<br>
