# Bug description
For the time domain stereo, the ICA is systematically under-estimated the time shift as seen in the figure below.
from top to bottom :
- input signal
- time shift (input to quantized) float
- time shift (input to quantized) fixed point
- difference between float and fixed point input to the quantizer
- output of the quantized float
- output of the quantized fixed point
- difference between float and fixed of the quantized output
{width=2318 height=1029}
The next figure shows the same plot as above, but with the correction proposed in !1135 . It can be seen that when the input to the quantize is the same between float and fixed point, the output is the same as well
{width=2309 height=1014}
