About LeCleach horns

There's an interesting thread on diyaudio, where Jean-Michel Le Cléac'h himself is answering questions about his very own horn expansion. The different horn expansion types are based on/follow different assumptions about how sound waves form and travel through air. "Jmmlc" developed one himself. Azurahorns and Musique Concrete horns are LeCleach horns, for instance. It's a very good thread, lots of theory in digestible chunks. Enjoy!
