Transposed stimuli induce phase locking to the envelope at high carrier frequencies

Evidence

The high-frequency stimulus was a ˵transposed stimulus,˶ which was a 4-kHz tone carrier amplitude-modulated with a half-wave rectified 125-Hz sinusoid (Bernstein and Trahiotis 2002 ). It is considered that the auditory-nerve firing is phase locked to the modulator waveform, which provides the cue for judging the ITD and modulation rate of the stimulus. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1039
