Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: In an MPEG Advanced Audio Coder (AAC), for each frequency subband, the quantization parameter called scale factor controls the quantization noise and the bit rate. Tuning this coder would require a characterization of the rate-distortion function per subband, which seems to be available only in a parametric manner. ,  show that an accurate model for the quantization noise, depending on the scale factor value, can lead to a simple expression of the relation beten the scale factor and the error por per subband. In other terms,  are now able to obtain an explicit writing of the distortion-rate function. In a second time,  apply these results to the coding algorithm in case of a fixed output bit rate and propose a new coding algorithm. Unlike the one described in the informative annex of the MPEG-2 standard, it makes use of a single loop and happens to be faster and more flexible towards psychoacoustic criteria.
