Abstract
A decoder for reproducing information from an encoded signal that has been frequency-domain transformed by a transform conversion circuit in response to audio signal samples grouped into time-domain blocks based on selected block time lengths, includes a reverse conversion transformation circuit that groups the frequency-domain transfer coefficients into transform blocks based on the block time length information used in the encoding operation and applies the inverse discrete transform function to generate time-domain signal sample blocks therefrom.
