摘要
A parameter calculator calculates lower resolution parametric information and interpolation information. On a decoder-side, an upmixer (500) is used for generating the output channels (502). The upmixer (500) uses high resolution parametric information (506) generated by a parameter interpolator (508) using the low resolution parametric information (510) and decoder-side derived interpolation information (512) or encoder-generated interpolation information (512) for selecting one of a plurality of different interpolation characteristics.
