Abstract:
The present document relates an audio encoding and decoding system (referred to as an audio codec system). In particular, the present document relates to a audio codec system which is particularly well suited for voice encoding/decoding. A transform-based speech encoder is configured to encode a speech signal into a bitstream is described. A speech decoder configured to decode audio signals from a bitstream is further described.

Claim (Index 1):
A method for decoding an encoded audio signal in a bitstream, the method comprising:\n determining prediction coefficients based on coefficient data comprised within the bitstream to determine quantized prediction coefficients; inversely quantizing the quantized prediction coefficients to determine dequantized prediction coefficients; and determining a plurality of spectral energy values for a corresponding plurality of frequency bands based on the dequantized prediction coefficients.
