Hi, Greg and Pau<br><br>I did some tests on SDIF files out of wave files and so far it works fine.<br>Now I am trying to find out the loop of a single note and store the loop in .xml file.<br>Here I have questions for each of you separately:<br>
<br>(1) for Greg<br>I compiled your makeLoop (from the examples folder) successfully.<br>But if I specify the start time and the end time of the steady state, makeLoopExe always "calculate 0 EarthMover's distance".<br>
If I do not specify the time, makeLoopExe would never finish. ( it gives dots ".................." )<br><br>Did you notice this problem before? Maybe it only happened to me.<br><br>Also, in your previous message you said you "turned off the database lookup function".<br>
Can you please explain more about what "the lookup function" is supposed to do and why you turned it off?<br><br>( I could see that you disabled the residual part in the SDIFInConfig. But I am not sure if this is what you were talking about... ) <br>
<br>(2) for Pau:<br>So far we have not decide which woodwind instrument we should work with.<br>Should I work on Saxophone or Oboe?<br>Do we have annotated saxophone notes from SALTO with all loop identified?<br><br>
I cut and labeled 72 oboe notes recorded in an anechoic chamber by hand (24 pitches C4-B5 * 3 different dynamics).<br>
It will take a while to find the loop for those notes. Before I proceed, I would like to make sure I am working on the right instrument :-) <br><br><br>Best regards,<br>Han, Yushen<br><br><div class="gmail_quote">On Sun, May 18, 2008 at 10:35 AM, Greg Kellum <<a href="mailto:greg.kellum@gmail.com">greg.kellum@gmail.com</a>> wrote:<br>

<br>
In response to point 3, I turned off the database lookup function at<br>
some point, because of an exception that kept occurring... I can't<br>
remember whether I eventually fixed this or not. I'll have to<br>
check...<br>
