摘要：

Typically, perceptual audio coders have followed a subband or transform coding scheme with forward-adaptive quantization,In this letter we present an alternative scheme which uses backward-adaptive quantization, We discuss the effects of this strategy on perceptual coding and show that it can be successfully applied.
