1 What's you're favorite Audio tutorial and reference links? (aside from the wonderful CB, of course)? I give Shure major kudos for their educational brochures they make available. They aren't just adware, they are full of understandable theory and real-world best practices. Raises the bar and satisfaction level for all. "Selecting & Using Wireless Microphone Systems" and "Microphone Selection and Techniques" are both really good with useful graphics for self and passing on to clients, students, or others who are learning the ropes. (I much prefer their 3D polar pattern graphics than the typical 2D ones, for educating the differences) http://shure.com/ProAudio/TechLibrary/index.htm http://shure.com/ProAudio/TechLibrary/EducationalArticles/index.htm 2 and this is a pretty cool flash page, I'd guess it was made by a forum user, but Shure is hosting it and I found it real interesting to play with basic mic type, polar patten, room reflectivity, distance, etc parameters. http://www.shure.com/stellent/group...ocuments/web_resource/us_pro_dir_amb_demo.swf General observations based on those examples: 1) parabolics bring up a sound, but are _Very_ tunnel sounding, and you still have to sort through the other material (background noise). A shotgun mic however, gets you just as good pickup without all the other ambient noise. 2) not much hearable difference between a cardoid and hyper-cardioid, but a hyper would still probably provide better feedback rejection. a WORLD of difference between the unidirectional (cardioid, super- and hyper-cardioid) and omni mics. Of course. Just fun to compare side-by-side so quickly. A picture being worth a thousand words, this is an audio "picture". Enjoy.
