These are all based on rate-distortion optimized coding using a perceptual distortion measure. We show how a number of well-known computationally efficient methods for incorporating perception in sinusoidal parameter estimation relate to minimizing this perceptual distortion measure. A number of methods for parametric coding of transients are compared and results of listening tests are presented. Finally, we show how the complexity of rate-distortion optimized audio coding can be reduced by rate-distortion estimation." }
