IIn the past, it has often been assumed that when a high-frequency resolution filter bank was used in a coding system, no easy access to the signal's temporal fine structure was possible. This paper presents the general framework for accessing and manipulating the temporal structure of signals by using the dual of the standard -LPC- paradigm, i.e. predicting in frequency instead of time. Examples for the application of this principle are given including the Temporal Noise Shaping (TNS) technique of the ISO/MPEG-2 Advanced Audio Coding System.
