* terminated string.

* parameter.
* @code OI_Printf("Identifier %~", &id, OI_UNICODE_UTF16_BE); @endcode

* 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.
@ingroup codec_internal

/**
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])
