  text: Microphone arrays represent the basis for many challenging acoustic sensing
    tasks. The accuracy of techniques like beamforming directly depends on a precise
    knowledge of the relative positions of the sensors used. Unfortunately, for certain
    use cases manually measuring the geometry of an array is not feasible due to practical
    constraints. In this paper we present an approach to unsupervised shape calibration
    of microphone array networks. We developed a hierarchical procedure that first
    performs local shape calibration based on coherence analysis and then employs
    SRP-PHAT in a network calibration method. Practical experiments demonstrate the
    effectiveness of our approach especially for highly reverberant acoustic environments.
