A Perceptual Spectral Difference Model for Binaural Signals

Document Thumbnail

This paper presents a perception based model for calculating the difference between two binaural signals to more accurately represent the perceptual relevance of spectral differences. A basic spectral difference calculation, the difference between the fast Fourier transforms (FFTs) of two audio signals, is not an accurate metric for human perception as the auditory system differs greatly in sensitivity depending on relative amplitude, frequency, and temporal aspects. The presented model is evaluated through objective measures and comparison to the results of a previously published listening test.
