# Issue description
In function `stereo_dft_dequantize_res_gains()` two comparisons take place that differ on the boundary value from that of fixed point.
In floating point we have:
```
index = ( ( ind1[i] < 15 ? 15 - ind1[i] : ind1[i] - 15 ) << 3 ) + ind2[i];
gout[i] = ind1[i] < 15 ? -dft_res_gains_q[index][0] : dft_res_gains_q[index][0];
```
but in fixed point:
```
IF( LE_16( ind1[i], 15 ) )
...
IF( LE_16( ind1[i], 15 ) )
...
```
both implementations should agree on the boundary value `ind1[i] = 15`. Please fix this.
