SpectralBridge: Adding High-Frequency Capability to Large Audio-Language Models
SpectralBridge is presented, a lightweight extension that gives a large audio-language model access to the 8-16 kHz band by joining low- and upper-band representations with time-aligned paired cross-frequency attention and improves both zero-shot transfer and downstream fine-tuning.
