QLoud is a tool to measure loudspeaker frequency response. Find it here: http://gaydenko.com/qloud/ Uwe has released Qwt v.5.0.0rc0. As a result, QLoud doesn't depend on any CVS tree now. v.0.16 is out - INSTALL is changed to be in accordance with Qwt development. Also, min. smoothing was reduced to 1/1024 :-) If you already use the app, you can stay with v.0.15 (no bugs were found). If you have rejected the app because of Qwt CVS-tree dependency - try it now :-) Andrew
