Patent JP-2008539462-A (JP)
IPC: G10L19/02
Filed: 2006-03-23
Abstract: The time needed to encode an input audio stream is reduced by dividing the stream into two or more overlapping segments of audio information blocks, applying an encoding process to each segment to generate encoded segments in parallel, and appending the encoded segments to form an encoded output signal. The encoding process is responsive to one or more control parameters. Some of the control parameters, which apply to a given block, are calculated from audio information in one or more previous blocks. The length of the overlap between adjacent segments is chosen such that the differences between control parameter values and corresponding reference values at the end of the overlap interval are small enough to avoid producing audible artifacts in a signal that is obtained by decoding the encoded output signal.
