SOX Multi-threading

Regarding “SOX Multi-threading” is this a feature already built in to Volumio? On this page changelog-t1575.html it states “Resampling options with Multithread Sox” listed in the changelog under 2.163 (06-05-2017).

I can’t find an option to enable or disable the feature as I can using Moode, is it enabled in Volumio automatically when resampling is turned on?
