On the use of backward adaptation in a perceptual audio coder
João M. O. S. Rodrigues, Ana Maria Tomé · IEEE Transactions on Speech and Audio Processing · 2000
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.
