Researchers have developed a new method to understand the internal workings of audio separation foundation models, specifically flow-matching transformers. By applying causal intervention principles, they identified a dual-pathway mechanism for text conditioning that influences semantic identity and acoustic structure. This analysis revealed an asynchronous layer convergence, where stable layers establish temporal scaffolds early, and faster layers refine details during sampling, leading to the proposal of Layer-Selective Attention Caching (LSAC) for computational efficiency.
