Fig. 1.

Color online: schematic representation of stimuli shown monaurally in panels a–d and binaurally in panel e. a AM reference high-rate pulse train with F0 of 125 Hz. b High-rate pulse train with F0 of 125 Hz with inserted SIPI pulses in every 1/SIPI rate interval; inset shows SIPI fraction. c SIPI phase conditions for F0 of 125 Hz. d SIPI phase conditions for F0 of 250 Hz. e Binaural illustration of pulse train with SIPI at 90° (from panel c), with ITD applied to the entire pulse train. SIPI, short inter-pulse interval; A, amplitude modulation. For more information on the SIPI phase, refer to the text
