SonicBench - Brightness: leaderboard

SonicBench (Sun et al., 2026) tests whether audio language models perceive physical properties of sound with two-option questions built from controlled contrasts far above human discrimination thresholds, each attribute asked as recognition of one clip and as comparison of two clips; abstentions count as wrong and random guessing scores 50. This board is the 200 questions on spectral brightness (NSynth); accuracy in percent, higher is better.

Metric: Accuracy (%; spectral brightness (NSynth); 100 recognition and 100 comparison two-option questions, greedy decoding, abstentions scored wrong; random 0.50). Source: arxiv.org. Saturation forecast: Estimated already saturated. 33 models tracked.
