Re-, Thanks for the fast answers! I've already collected Perl HTML modules and will see what I can do with that. I like the idea of diving in and having a try to find the language that will best suit to one's feelings, but I was wondering which one would handle audio files better. There seem to be plenty of Perl modules on the CPAN archive, including the Audio family (and Number::SPICE I may discover later...): what about Python? Maybe "aifc" (http://www.python.org/doc/1.5.2p2/lib/module-aifc.html)? I suppose Perl is the closest to Matlab as also close to C/C++? I'll document myself on Ruby too! On RubyCentral (http://www.rubycentral.com) I guess? Before anyone asks, let's say I've cheated a bit: I wrap an Akp to Sfz converter inside my script: http://www.rgcaudio.com/downloads/freeware/Akp2Sfz.zip Cheers, Christian
