APPARATUS AND METHOD FOR GENERATING MULTI-CHANNEL SYNTHESIZER CONTROL SIGNAL AND APPARATUS AND METHOD FOR MULTI-CHANNEL SYNTHESIZING

摘要

On an encoder-side, a multi-channel input signal is analyzed for obtaining smoothing control information, which is to be used by a decoder-side multi-channel synthesis for smoothing quantized transmitted parameters or values derived from the quantized transmitted parameters for providing an improved subjective audio quality in particular for slowly moving point sources and rapidly moving point sources having tonal material such as fast moving sinusoids.
