FIG. 9.

Cochlear filtering preserves phase-based envelope differences in AN fibers. ρ _ENV is shown as a function of ΔF0 for F0-shift conditions (A) and Freq-shift conditions (B), for an AN fiber with CF = 1.61 kHz. Tone complexes had individual components with random starting phase, even for the zero-shift condition with this fiber. The shaded region adjacent to the ordinate emphasizes that ρ _ENV values are scattered between 0.3 and 1 (even for zero-shift conditions). Given the independence of ρ _ENV on ΔF0 or ΔF, no lines were fit to the data.
