A schematic illustration of the calculation of the SIED cue. Envelopes were extracted from the analytic signals, which were obtained using the Hilbert transform of the fourth-order gammatone filtered waveforms. The center frequency of the gammatone filter was set to the tone frequency of 500 Hz. The SIED was half-wave rectified and integrated over time to obtain the SIED DV.
