After several hours experimenting with functionality I found this plugin works as advertised. The documentation and examples are thorough and extensive. Simon anticipated my questions well on many occasions. After trying at least 30 different audio solutions (I have lots of parameter requirements), this one seems to be addressing almost all of my needs and concerns. It's rare that a WP plugin has such clear and extensive documentation. It's above and beyond, but really what every good plugin should have. Nicely done.
