I was searching around on the Google for some training resources, and I happened to come across this: The Audio Masterclass Music Production and Sound Engineering Online Course It seems quite thorough, including instruction, self-assessment, and a 12-volume media library with a myriad of acoustic sample files for comparison. Has anyone enrolled/purchased this set? Is it as comprehensive and worthwhile as it claims? I'm seriously considering purchasing the set, however I would like to know if there are any other opinions before spending the $477. Also, are there any other resources in this format for other areas of production (i.e., lighting, scenic, etc.)? It would be incredible to have a huge library of instructional resources in this kind of format.
