Method and apparatus for time scaling of a signal

摘要: A decoder receives (501) a bitstream comprising an encoded mono signal and stereo data. time scale processor (503) generates scaled signal. time-to­frequency frequency sample blocks of the signal, block length being fixed independent scaling. parametric (509) for these are converted to domain by frequency-to-time (511). synchronization (515) synchronizes data with determining association between parameter value block. The is used determine synchronized values that other blocks. invention particularly suitable low complexity generation signals from MPEG-4 signals.
