Tools like the "nulling" upmixer, which aims to perfectly recreate the original stereo from a 5.1 mix, are emerging, though development is ongoing. Meanwhile, mainstream converters like fre:ac are adding native 5.1 support, and hardware upmixing is becoming more flexible, with units like the Areal supporting custom loudspeaker arrays up to 7.1.4. The technology is evolving from a niche professional process to a standard feature for all listeners.
