1959 linearly interpolates between the previous weights and the current ones, using
1960 zeros for the previous weights if none are available.
1961 These prediction weights are never included in a mono Opus frame, and the
1962 previous weights are reset to zeros on any transition from mono to stereo.
1965 In that case, the previous weights are used, again substituting in zeros if no
1966 previous weights are available since the last decoder reset
1971 To summarize, these weights are coded if and only if
1979 The prediction weights are coded in three separate pieces, which are decoded

2799 The weights are derived directly from the stage-1 codebook vector.

6601 Spectral tilt. A weighted average of the subband SNRs, with positive weights
6602 for the low subbands and negative weights for the high subbands.
7033 The weights for the quantization errors are the Inverse
7036 These weights are referred to here as Laroia weights.
7046 For each of the N codebook vectors the Laroia weights corresponding
7049 vector is scaled by the square roots of these Laroia weights.
7054 And by scaling with Laroia weights determined from the first-stage
