Synthblitz audio has released Spazial Pro, a stereo expander VST plug-in for Windows.
Spazial Pro is an evolution of Spazial Free that adds new commands such as delay on channels L-R and separate knobs for mid-side processor, the chorus, and other changes on the parameters. It also adds two equalizers working separately on the mid and side channel. The integrated Limiter allows to gain some point RMS by simply raising up the master volume, useful for a mastering session.
Spazial Pro is designed for guitarists but works well in recording and with any type of music.
