+ * Explanation of the adjustToFitBitpool inner loop.
+ *
+ * The inner loop computes the effect of adjusting the bit allocation up or
+ * down. Allocations must be 0 or in the range 2..16. This is accomplished by
+ * the following code:
+ *
+ * for (s = bands - 1; s >= 0; --s) {
+ * OI_INT bits = bitadjust + bitneeds[s];
+ * bits = bits < 2 ? 0 : bits;
+ * bits = bits > 16 ? 16 : bits;
+ * count += bits;
+ * }
+ *
+ * This loop can be optimized to perform 4 operations at a time as follows:
+ *
+ * Adjustment is computed as a 7 bit signed value and added to the bitneed.
+ *
+ * Negative allocations are zeroed by masking. (n & 0x40) >> 6 puts the
+ * sign bit into bit 0, adding this to 0x7F give us a mask of 0x80
+ * for -ve values and 0x7F for +ve values.
+ *
+ * n &= 0x7F + (n & 0x40) >> 6)
+ *
+ * Allocations greater than 16 are truncated to 16. Adjusted allocations are in
+ * the range 0..31 so we know that bit 4 indicates values >= 16. We use this bit
+ * to create a mask that zeroes bits 0 .. 3 if bit 4 is set.
+ *
+ * n &= (15 + (n >> 4))
+ *
+ * Allocations of 1 are disallowed. Add and shift creates a mask that
+ * eliminates the illegal value
+ *
+ * n &= ((n + 14) >> 4) | 0x1E
+ *
+ * These operations can be performed in 8 bits without overflowing so we can
+ * operate on 4 values at once.

+ Dequantizer for SBC decoder; reconstructs quantized representation of subband samples.

+/**
+ This function is a fixed-point approximation of a modification of the following
+ dequantization operation defined in the spec, as inferred from section 12.6.4:
+
+ @code
+ dequant = 2^(scale_factor+1) * ((raw * 2.0 + 1.0) / ((2^bits) - 1) - 1)
+
+ 2 <= bits <= 16
+ 0 <= raw < (2^bits)-1 (the -1 is because quantized values with all 1's are forbidden)
+
+ -65535 < dequant < 65535
+ @endcode
+
+ The code below computes the dequantized value divided by a scaling constant
+ equal to about 1.38. This constant is chosen to ensure that the entry in the
+ dequant_long_scaled table for 16 bits is as accurate as possible, since it has
+ the least relative precision available to it due to its small magnitude.
+
+ This routine outputs in Q16.15 format.
+
+ The helper array dequant_long is defined as follows:
+
+ @code
+ dequant_long_long[bits] = round(2^31 * 1/((2^bits - 1) / 1.38...) for 2 <= bits <= 16
+ @endcode
+
+
+ Additionally, the table entries have the following property:
+
+ @code
+ dequant_long_scaled[bits] <= 2^31 / ((2^bits - 1)) for 2 <= bits <= 16
+ @endcode
+
+ Therefore
+
+ @code
+ d = 2 * raw + 1 1 <= d <= 2^bits - 2
+
+ d' = d * dequant_long[bits]
+
+ d * dequant_long_scaled[bits] <= (2^bits - 2) * (2^31 / (2^bits - 1))
+ d * dequant_long_scaled[bits] <= 2^31 * (2^bits - 2)/(2^bits - 1) < 2^31
+ @endcode
+
+ Therefore, d' doesn't overflow a signed 32-bit value.
+
+ @code
+
+ d' =~ 2^31 * (raw * 2.0 + 1.0) / (2^bits - 1) / 1.38...
+
+ result = d' - 2^31/1.38... =~ 2^31 * ((raw * 2.0 + 1.0) / (2^bits - 1) - 1) / 1.38...
+
+ result is therefore a scaled approximation to dequant. It remains only to
+ turn 2^31 into 2^(scale_factor+1). Since we're aiming for Q16.15 format,
+ this is achieved by shifting right by (15-scale_factor):
+
+ (2^31 * x) >> (15-scale_factor) =~ 2^(31-15+scale_factor) * x = 2^15 * 2^(1+scale_factor) * x

+/** @file
+
+This file, along with synthesis-generated.c, contains the synthesis
+filterbank routines. The operations performed correspond to the
+operations described in A2DP Appendix B, Figure 12.3. Several
+mathematical optimizations are performed, particularly for the
+8-subband case.
+
+One important optimization is to note that the "matrixing" operation
+can be decomposed into the product of a type II discrete cosine kernel
+and another, sparse matrix.
+
+According to Fig 12.3, in the 8-subband case,
+@code
+ N[k][i] = cos((i+0.5)*(k+4)*pi/8), k = 0..15 and i = 0..7
+@endcode
+
+N can be factored as R * C2, where C2 is an 8-point type II discrete
+cosine kernel given by
+@code
+ C2[k][i] = cos((i+0.5)*k*pi/8)), k = 0..7 and i = 0..7
+@endcode
+
+R turns out to be a sparse 16x8 matrix with the following non-zero
+entries:
+@code
+ R[k][k+4] = 1, k = 0..3
+ R[k][abs(12-k)] = -1, k = 5..15
+@endcode
+
+The spec describes computing V[0..15] as N * R.
+@code
+ V[0..15] = N * R = (R * C2) * R = R * (C2 * R)
+@endcode
+
+C2 * R corresponds to computing the discrete cosine transform of R, so
+V[0..15] can be computed by taking the DCT of R followed by assignment
+and selective negation of the DCT result into V.
+
+ Although this was derived empirically using GNU Octave, it is
+ formally demonstrated in, e.g., Liu, Chi-Min and Lee,
+ Wen-Chieh. "A Unified Fast Algorithm for Cosine Modulated
+ Filter Banks in Current Audio Coding Standards." Journal of
+ the AES 47 (December 1999): 1061.
+
+Given the shift operation performed prior to computing V[0..15], it is
+clear that V[0..159] represents a rolling history of the 10 most
+recent groups of blocks input to the synthesis operation. Interpreting
+the matrix N in light of its factorization into C2 and R, R's
+sparseness has implications for interpreting the values in V. In
+particular, there is considerable redundancy in the values stored in
+V. Furthermore, since R[4][0..7] are all zeros, one out of every 16
+values in V will be zero regardless of the input data. Within each
+block of 16 values in V, fully half of them are redundant or
+irrelevant:
+
+@code
+ V[ 0] = DCT[4]
+ V[ 1] = DCT[5]
+ V[ 2] = DCT[6]
+ V[ 3] = DCT[7]
+ V[ 4] = 0
+ V[ 5] = -DCT[7] = -V[3] (redundant)
+ V[ 6] = -DCT[6] = -V[2] (redundant)
+ V[ 7] = -DCT[5] = -V[1] (redundant)
+ V[ 8] = -DCT[4] = -V[0] (redundant)
+ V[ 9] = -DCT[3]
+ V[10] = -DCT[2]
+ V[11] = -DCT[1]
+ V[12] = -DCT[0]
+ V[13] = -DCT[1] = V[11] (redundant)
+ V[14] = -DCT[2] = V[10] (redundant)
+ V[15] = -DCT[3] = V[ 9] (redundant)
+@endcode
+
+Since the elements of V beyond 15 were originally computed the same
+way during a previous run, what holds true for V[x] also holds true
+for V[x+16]. Thus, so long as care is taken to maintain the mapping,
+we need only actually store the unique values, which correspond to the
+output of the DCT, in some cases inverted. In fact, instead of storing
+V[0..159], we could store DCT[0..79] which would contain a history of
+DCT results. More on this in a bit.
+
+Going back to figure 12.3 in the spec, it should be clear that the
+vector U need not actually be explicitly constructed, but that with
+suitable indexing into V during the window operation, the same end can
+be accomplished. In the same spirit of the pseudocode shown in the
+figure, the following is the construction of W without using U:
+
+@code
+ for i=0 to 79 do
+ W[i] = D[i]*VSIGN(i)*V[remap_V(i)] where remap_V(i) = 32*(int(i/16)) + (i % 16) + (i % 16 >= 8 ? 16 : 0)
+ and VSIGN(i) maps i%16 into {1, 1, 1, 1, 0, -1, -1, -1, -1, 1, 1, 1, 1, 1, 1 }
+ These values correspond to the
+ signs of the redundant values as
+ shown in the explanation three
+ paragraphs above.
+@endcode
+
+We saw above how V[4..8,13..15] (and by extension
+V[(4..8,13..15)+16*n]) can be defined in terms of other elements
+within the subblock of V. V[0..3,9..12] correspond to DCT elements.
+
+@code
+ for i=0 to 79 do
+ W[i] = D[i]*DSIGN(i)*DCT[remap_DCT(i)]
+@endcode
+
+The DCT is calculated using the Arai-Agui-Nakajima factorization,
+which saves some computation by producing output that needs to be
+multiplied by scaling factors before being used.
+
+@code
+ for i=0 to 79 do
+ W[i] = D[i]*SCALE[i%8]*AAN_DCT[remap_DCT(i)]
+@endcode
+
+D can be premultiplied with the DCT scaling factors to yield
+
+@code
+ for i=0 to 79 do
+ W[i] = DSCALED[i]*AAN_DCT[remap_DCT(i)] where DSCALED[i] = D[i]*SCALE[i%8]
+@endcode
+
+The output samples X[0..7] are defined as sums of W:
+
+@code
+ X[j] = sum{i=0..9}(W[j+8*i])
