In this work the software library for binaural sound localization is presented. The main purpose of the library are the applications for localization tasks in audio systems based on two microphones. The implemented mechanisms include binaural single sound source localization, ITD (Interaural Time Difference) and ILD (Interaural Level Difference) cues and support real-time analysis. LibLaura is written in C++ language and is easily extensible to support new features, time delay estimators and user-defined callbacks.
