AB  - A class of re?ector localization techniques use multichannel room impulse responses (RIRs) for the visualization of room re?ections on 2D maps. In this paper, we focus on a setup comprising a linear loudspeaker array and a single microphone, which has become practically more relevant given the growing popularity of soundbars. First, the state-of-the-art visualization techniques developed for the generation of 2D time-domain direction-of-arrival (DOA) maps describing the temporal evolution of room re?ections are reviewed, and then an alternative high-resolution mapping approach is introduced. The performances of the existing techniques and the proposed method are compared using simulated and experimental multichannel RIR data generated in various room conditions.
