MIRAGE augments 2-microphone pairs with learning-based early-echo estimation and physics-based aggregation to enable azimuth and elevation source localization in simulated data with one reflective surface.
We model the problem as multi-target regression, with interaural level difference (ILD) and interaural phase difference (IPD) as input features, andV ∈ R3 as output parameters
