Version 1.2 of the Vamp plugin SDK is now available.
http://www.vamp-plugins.org/
Vamp is a plugin API for audio analysis and feature extraction plugins written
in C or C++. Its SDK features an easy-to-use set of C++ classes for plugin
and host developers, a reference host implementation, example plugins, and
documentation. It is supported across Linux, OS/X and Windows.
Version 1.2 contains a further addition to the host extension classes
introduced in 1.1: a buffering adapter that hosts may use to avoid having to
negotiate the plugin's preferred input step and block sizes.
Plugins and hosts remain 100% binary compatible with those built using the 1.0
version of the SDK.
