SRA is a web application that calculates the auditory roughness of sound signals, based on a roughness calculation model by Dr. Pantelis N. Vassilakis. Sound files are analyzed using a spectral analysis method developed by Dr. Kelly Fitz & colleagues, and the spectral parameters are fed to the roughness calculation model. Programmed by Kelly Fitz and coordinated by Drs. Jonathan Middleton and Pantelis N. Vassilakis. Keywords: Spectral analysis, signal analysis, roughness, dissonance, consonance, timbre, spectrum, Fourier, acoustics, psychoacoustics.
