Version 1.3 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 1.3 is a maintenance release, with several bugfixes (almost all of which only affect hosts, not plugins) and no new features. Changes since 1.2: * PluginBufferingAdapter has several important fixes to bugs that could cause incorrect timings or output descriptors to be returned * Conversion between real-time and frames has been improved to avoid rounding error in round-trip calculations * Plugin lookup no longer relies on non-portable DT_REG * The SDK now compiles with gcc 4.3 (knowing my luck it probably won't, but it's supposed to) Plugins and hosts remain binary compatible with those built using the 1.0 version of the SDK.
