A test plugin for use by developers working on Vamp plugin hosts.
This plugin does not carry out any real work. It simply provides a variety of outputs with different output descriptors, and returns some test values that can be used to check whether the host is interpreting the output sample type, sample rate, and bin counts correctly. Read a description here.
If you are developing plugins rather than hosts, and you want help in testing them, look instead at the Vamp Plugin Tester.
