Vamp Plugin SDK

h1. Output Sample Type and Sample Rate

A Vamp plugin takes audio as input, as a series of process blocks with associated timestamps, and returns a series of "feature structures". (See diagram.)

Each returned feature might have a timestamp... or it might not. Whether a timestamp is provided -- and, if it is provided, what it means -- are determined by the "sample type" and "sample rate" properties of the plugin output that returns the feature.
