Re: [LAU] sample preview program?

After installing ' waf.noarch 0:1.5.18-1.fc12' and rebuilding, it runs! It's works very nice and all, and it's good to know I can build a jack app this easily... so how would you go about adding a spectrogram/waveform display for the samples you display, e.g. http://www.mega-nerd.com/libsndfile/tools/#spectrogram . And then using that as a visual reference, be able to zoom and drag out regions on-top of the waveform or spectrogram. Then use the dimensions of the regions to play in the loop, preferably, animating a cursor in real-time as the sound plays. Of course you should be able to create and destroy these loopers as independent "UI units" within a scrolling region that can hold an infinite number of playing loops... as well as dynamically collapse the "view" of the loop data to include a polar spectrogram display, ala http://freewheeling.sourceforge.net/shots.shtml but without the reptilian GUI. ......................................... gnulem-120-.../Vala/PreHear> delete -rf build/ gnulem-121-.../Vala/PreHear> ./waf configure Setting build options & flags...
