    $\begingroup$ The article mentions (pp. 458, second column right at the first paragraph) that the gain factors are non-negative scalars, and if I am not mistaken, in the formulation, they are supposed to be real, too. In this regard, it would be better to get the absolute values of the gains and use those. If you think about it, negative gains would just mean a phase inversion, which is not relevant to VBAP (as far as I am aware). $\endgroup$ Commented Jan 9 at 10:18
  • $\begingroup$ @ZaellixA Thank you for your answer.If I understand well you are telling me to take the absolute value when I get a negative value.Wouldn't this result in a loud gain (My gain can only go from 0 to anything ) in case of -2 for example. $\endgroup$ Commented Jan 9 at 10:25
  • $\begingroup$ Well, if I understand the article correctly, this shouldn’t be a problem. If you get a -2 gain, isn’t that supposed to be a gain of 2 with a negative phase? If not, could you please clarify why? $\endgroup$ Commented Jan 9 at 10:27
  • $\begingroup$ @ZaellixA Honestly I don't know this is why I've asked SE.Have you had a chance to look at the code does it look correct (btw I'll will try adding the absolute value). Thanks in advance $\endgroup$ Commented Jan 9 at 10:29
