thanks everybody.. this goes by far beyond my capabilities, so i decided to turn<br>it around and create a sample-based patch. <br>the basic idea is to control a light installation through sound. 60 neon tubes are controlled
<br>via a custom built max patch. i want to connect the brightness of these tubes to the sound of breathing. my first thought was that it would be easier to deduct data from a<br>patch based on synthesis. after the information i gathered from the list i realize that this
<br>is an immense task that has its focus only next to my intention. so i decided to create a <br>sample based patch. at the moment i am using [fiddle] to read the amplitude of the recorded breath sounds.. however there are some troubles, like its very, very jumpy..
<br>it is also difficult to find a sonically equivalent parameter to "breath in.. breath out".. <br>pitch doesnt work.. [env] only reads the RMS so it does not change too much.. <br>amplitude is close to what we hear as rising and falling, but still very far from the natural
<br>perception.. maybe someone has an idea ? anyways.. i will keep you updated.. : )<br><br>alexandre d. <br><br><br><div><span class="gmail_quote">On 10/07/07, <b class="gmail_sendername">Thomas Grill</b> <<a href="mailto:email@example.com">
