Version 1.1b 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 1.1b is a minor update with a small number of build and bug fixes. The prior version 1.1 of the SDK introduced a new set of classes designed to make it very simple for an application to use Vamp plugins, without needing to do complicated plugin lookup or audio processing themselves. Plugins and hosts remain 100% binary compatible with those built using the 1.0 version of the SDK. Chris
