The openSMILE tool enables you to extract large audio feature spaces in realtime for emotion and sentiment analysis from audio and video. It is written in C++ and is available as both a standalone commandline executable as well as a dynamic library (A GUI version is to come soon). The main features of openSMILE are its capability of on-line incremental processing and its modularity. Feature extractor components can be freely interconnected to create new and custom features, all via a simple configuration file. New components can be added to openSMILE via an easy plugin interface and a comprehensive API. openSMILE is free software licensed under the GPL license and is currently available via Subversion [1] in a pre-release state [2].
