   Accurate modeling of spatial acoustics is critical for immersive and intelligible audio in confined, resonant environments such as car cabins. We propose INFER (Implicit Neural Frequency Response fields), a frequency-domain neural framework jointly conditioned on source and receiver positions and orientations to directly learn complex-valued frequency response fields inside confined, resonant environments. Our approach significantly outperforms time- and hybrid-domain baselines on both simulated and real-world automotive datasets, cutting average magnitude and phase reconstruction errors by over 39% and 51%, respectively.
