Envelope ITDs at high carrier frequencies are tested using transposed tones.

Evidence

For EEG recordings to ITDs conveyed in the stimulus envelope, 3000-Hz tones were modulated with a transposed envelope (Bernstein and Trahiotis 2002 ) at 128 Hz, and a second-order AM (41 Hz) applied diotically. IPDs of the 128-Hz envelopes were switched between ±90° IPD (around 0°) or from systematically between 0° and 180° (i.e. transposed phase of ‑90° in one ear and + 90° in the other). — Dijk, Pim van, Physiology, Psychoacoustics and…, 2961
