Abstract:
1. Method of decoding an encoded power spectral envelope of a stereo signal or a multichannel signal, comprising: receiving the encoded power spectral envelope of the stereo signal or the multichannel signal having a first channel and a second channel, the first channel and the second channel having a set of frequency bands, the encoded power spectral envelope being represented by a balance parameter for each frequency band and a level parameter representing a total power of the first channel and the second channel for each frequency band; and converting, by a converter, the balance parameters and the level parameters into power values of the first channel and the second channel, wherein the step of converting is performed based on the following equations: wherein P wherein P wherein B is the balance parameter, and wherein P is the level parameter, wherein the converter comprises a hardware implementation.
