Abstract:
There are provided decoding and encoding methods for encoding and decoding of multichannel audio content for playback on a speaker configuration with N channels. The decoding method comprises decoding, in a first decoding module, M input audio signals into M mid signals which are suitable for playback on a speaker configuration with M channels; and for each of the N channels in excess of M channels, receiving an additional input audio signal corresponding to one of the M mid signals and decoding the input audio signal and its corresponding mid signal so as to generate a stereo signal including a first and a second audio signal which are suitable for playback on two of the N channels of the speaker configuration.

Claim (Index 2):
The method according to  claim 1 , wherein the waveform-coded mid signal comprises spectral data corresponding to frequencies up to a second frequency, the method further comprising:\n extending the mid signal to a frequency range above the second frequency by performing high frequency reconstruction prior to performing parametric upmixing.
