LOCATA challenge - evaluation tasks and measures

Sound source localization and tracking algorithms provide estimates of the positional information about active sound sources in acous- tic environments. Despite substantial advances and significant in- terest in the research community, a comprehensive benchmarking campaign of the various approaches using a common database of audio recordings has, to date, not been performed. The aim of the IEEE-AASP Challenge on sound source localization and tracking (LOCATA) is to objectively benchmark state-of-the-art localization and tracking algorithms using an open-access data corpus of record- ings for scenarios typically encountered in audio and acoustic signal processing applications. The challenge tasks range from the local- ization of a single source with a static microphone array to tracking of multiple moving sources with a moving microphone array. This paper provides an overview of the challenge tasks, describes the per- formance measures used for evaluation of the LOCATA Challenge, and presents baseline results for the development dataset
