PitchBench - Pitch under Time Stretching: leaderboard

Pitch hearing in audio-language models (PitchBench, Liessens Dujardin et al., 2026): naming the sounding pitch of a tone after resampling or pitch-preserving time stretching (192 stimuli), with synthetic stimuli. A pitch answer counts when any of MIDI number, scientific pitch notation or frequency is right; accuracy in percent, higher is better.

Metric: Accuracy (%; name the sounding pitch after resampling or time stretching). Source: arxiv.org. Saturation forecast: Around June 2028. 6 models tracked.
