Patent ID: 8744843

Claim:
A multi-mode audio decoder for providing a decoded representation of audio content on the basis of an encoded bitstream, a multi-mode audio decoder comprising a memory; and a processor configured to decode a global gain value per frame of the encoded bitstream, wherein a first subset of the frames being coded in a first coding mode and a second subset of the frames being coded in a second coding mode, with each frame of the second subset being composed of more than one sub-frames, decode, per sub-frame of at least a subset of the sub-frames of the second subset of frames, a corresponding bitstream element differentially to the global gain value of the respective frame, and complete decoding the bitstream using the global gain value and the corresponding bitstream element in decoding the sub-frames of the at least subset of the sub-frames of the second subset of frames and the global gain value in decoding the first subset of frames, wherein the multi-mode audio decoder is configured such that a change of the global gain value of the frames within the encoded bitstream results in an adjustment of an output level of the decoded representation of the audio content.
