Abstract
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
