Researchers have identified structural bottlenecks in end-to-end neural audio models that limit their ability to directly represent interpretable features like pitch and timbre. These bottlenecks, predictable from the model's architecture, collapse primitives into alias equivalence classes and restrict frequency resolution. A post-hoc intervention called Gabor Latent Refactorization (GLRF) was introduced, which re-expresses encoder latents in a frequency-localized basis. GLRF successfully reduces filter bandwidths and improves control over attributes like pitch without retraining, while preserving reconstruction fidelity. AI
