Transformer Model Reconstructs Audio Spatialization Data From Sparse Inputs

By PulseAugur Editorial · [1 sources] ·

Researchers have developed HRIR-Former, a novel time-domain Transformer model designed to reconstruct Head-Related Impulse Responses (HRIRs) at arbitrary directions from sparse measurements. Unlike previous methods that often operate in the frequency domain or rely on minimum-phase assumptions, HRIR-Former reconstructs HRIRs directly in the time domain, avoiding potential degradation in temporal fidelity and spatial continuity. The model incorporates sinusoidal spatial features, a Conv1D refinement module, and auxiliary heads for interaural time and level differences, demonstrating improved performance on the SONICOM dataset compared to existing techniques.

    HRIR-Former: Grid-Free Time-Domain Reconstruction of Head-Related Impulse Responses with a Spatially Encoded Transformer

    arXiv:2603.27998v2 Announce Type: replace-cross Abstract: Individualized head-related impulse responses (HRIRs) enable binaural rendering, but dense per-listener measurements are costly. We address HRIR spatial up-sampling from sparse per-listener measurements: given a few measur…
