Abstract
A decoding apparatus () is disclosed which includes: a storing means () for storing encoded audio signals including multi-channel audio signals; a transforming means () for transforming the encoded audio signals to generate transform block-based audio signals in a time domain; a window processing means () for multiplying the transform block-based audio signals by a product of a mixture ratio of the audio signals and a first window function, the product being a second window function; a synthesizing means () for overlapping the multiplied transform block-based audio signals to synthesize audio signals of respective channels; and a mixing means () for mixing audio signals of the respective channels between the channels to generate a downmixed audio signal. Furthermore, an encoding apparatus is also disclosed which downmixes the multi-channel audio signals, encodes the downmixed audio signals, and generates the encoded, downmixed audio signals.
