This work examined the effect of band power weighting on understanding stimuli synthesized with temporal envelope or Hilbert-fine-structure (HFS) waveforms. The power of modulated carrier in a vocoder model or HFS waveform was level-matched to that of the bandpass filtered signal (matched condition) or equalized across bands (flat condition). The processed stimuli were played to normal-hearing listeners to recognize. For both vocoded and HFS stimuli, there was no significant performance
