Spike-Timing-Based Computation in Sound Localization
Figure 4
Cochleograms of test sounds used in simulations: white noise; vowel-consonant-vowel (VCV); instruments; pure tones (between 150 Hz and 5 kHz, uniformly distributed in ERB scale).
The cochleograms show the output of the gammatone filters used in the model, half-wave rectified and low-pass filtered [56].
