SAIL processes Mel-spectrograms, which represent sound content, separately from interaural phase differences, which encode timing differences between the ears and help locate sounds.
Separating sound identity and location improves multisource spatial audio reasoning
SAIL keeps acoustic semantics and spatial cues in distinct, source-specific streams before passing them to a language model.
