ats - Spectral modeling system

ATS is a spectral modeling system based on a sinusoidal plus
critical-band noise decomposition. Psychoacoustic processing informs
the system's sinusoidal tracking and noise modeling
algorithms. Perceptual Audio Coding (PAC) techniques such as
Signal-to-Mask Ratio (SMR) evaluation are used to achieve perceptually
accurate sinusoidal tracking. SMR values are also used as a
psychoacoustic metric to determine the perceptual relevance of
partials during analysis data postprocessing. The system's noise
component is modeled using Bark-scale frequency warping and sub-band
noise energy evaluation. Noise energy at the sub-bands is then
distributed on a frame-by-frame basis among the partials resulting in
a compact hybrid representation based on noise modulated sinusoidal
