My goal is a quick and dirty program that will measure the time between two large audio events (in the input sound buffer, live recording.) Essentially what I want to do is use ChucK for practical demonstrations of simple physics... IE demonstrating average velocity of a falling object (that generates a sufficiently loud event when it is released and when it hits the floor.)<br> <br>Any tips where to start on this project? <br><br><br>Ryan<br><br><br><br> <br>_______________________________________________<br> chuck-users mailing list<br> <a href="mailto:chuck-users@lists.cs.princeton.edu">chuck-users@lists.cs.princeton.edu</a><br> <a href="https://lists.cs.princeton.edu/mailman/listinfo/chuck-users" target="_blank">https://lists.cs.princeton.edu/mailman/listinfo/chuck-users</a><br> <br></blockquote></div><br><br clear="all"><br>-- <br>Release me, insect, or I will destroy the Cosmos!<br> </div> _______________________________________________<br>chuck-users mailing list<br><a href="mailto:chuck-users@lists.cs.princeton.edu">chuck-users@lists.cs.princeton.edu</a><br>https://lists.cs.princeton.edu/mailman/listinfo/chuck-users<br></blockquote></div><br></div></body></html>
