A new approach to audio coding based on optimization techniques is presented. In contrast to existing coding algorithms, this framework is based on a signal-adaptive filter bank which is controlled using optimization techniques for a rate distortion or perceptual metric. Dynamic programming techniques allow one to optimize the time-frequency tiling of the filter bank and to minimize the distortion for a given bit budget.
