SonicBench - Loudness: 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 loudness (contrasts of a few loudness units); accuracy in percent, higher is better.
Metric: Accuracy (%; loudness (integrated LUFS contrasts of at least 2-3 LU); 100 recognition and 100 comparison two-option questions, greedy decoding, abstentions scored wrong; random 0.50). Source: arxiv.org. Saturation forecast: Around February 2027. 33 models tracked.
