摘要： Methods and devices provide improved perceived quality of an audio (or other) coded signal at a low bit-rate. An input signal may be split into an outlier portion and a stationary portion. The outlier portion of the input signal may be encoded. The stationary portion may be divided into subvectors. Each subvector may be classified as trivial or non-trivial. Each trivial subvector may be encoded using a pre-defined pattern. Each non-trivial subvector may be encoded with at least one location of at least one significant sample and a sign of the significant sample.
