[LAD] swh plugins problem/addition

Hallo Steve, list ! I just noticed, that the "triple band parametric with shelves" LADSPA plugin generates a DC offset (tried version 0.4.15 and 0.4.14). The offset is not always the same: first when I create the plugin, there is no offset. Then I pressed play/stop (in ardour) and the DC offset was here - also the amount of the offset is somehow changing when I play with different parameters (but I did not find out a real correspondens). However, when I use the "Single band parametric" and the shelves alone I don't get an offest (which should be the same code ?). I also made some other small additions to your plugin collection: - single low and high shelving filters (see attached files): they are the same code as in "triple band parametric with shelves", because I often need only a single shelving filter - in the "single band parametric" the slider to change the frequency was linear, I changed this to logarithmic (file attached) Maybe you could include those plugins/changes in your collection, at least for me they are quite usefull.
