Validation of web-based testing for classic psychoacoustic tasks with diotic stimuli. Psychometric functions were measured for fundamental-frequency (F0) discrimination (A), and gap detection (B). F0 discmination limens were around 0.5% for F0 = 110 Hz, and gap thresholds were around 6 ms, consistent with lab-based data with similar stimuli. Horizontal error bars in orange indicate the 95% confidence interval of the mean threshold estimated from $N=100$ subjects
