Abstract
Systems, methods, and storage media for audio processing adapted to voice encoding/decoding are disclosed. In some implementations, a system is adapted to determine prediction coefficients based on coefficient data included within a bitstream to determine quantized prediction coefficients, the coefficient data including one or more model parameters indicating at least one attribute of a signal model. The system inversely quantizes the quantized prediction coefficients to determine dequantized prediction coefficients. The system then determines multiple spectral energy values for multiple corresponding frequency bands based on the dequantized prediction coefficients.
