Description
In MDCT-Stereo stereo processing in the decoder, one of the channels is scaled to undo the ILD compensation. There is a bug in the scaling of the spectrum that can lead to only half of the spectrum being scaled up, while the upper half stays at too low level then. Fix is implemented and potentially affects BE in all MDCT-Stereo modes.
