arXiv:2605.03929v4 Announce Type: replace-cross Abstract: Stem retrieval, the task of matching missing stems to a given audio submix, is a key challenge currently limited by models that discard temporal information. We introduce PHALAR, a contrastive framework achieving a relative accuracy increase of up to $\approx 70\%$ over the state-of-the-art while requiring $<50\%$ of the parameters and a 7$\times$ training speedup. By utilizing a Learned Spectral Pooling layer and a complex-valued head, PHALAR enforces pitch-equivariant and phase-equivariant biases. PHALAR establishes new retrieval stat
Advances in AI research, particularly in neural network architectures and computational efficiency, are continuously pushing the boundaries of what is possible in specialized domains like audio processing.
This development indicates significant progress in creating more efficient and accurate AI models for media content analysis and music production, potentially impacting entertainment and creative industries.
New algorithms can now process complex audio data more efficiently and accurately, leading to faster development cycles and reduced computational costs for tasks like stem retrieval and music generation.
