Our friends at Goodhertz, makers of plugins, have released a free version of their Mastering plugin Midside, Midside Matrix. They say;
Midside Matrix pares down our acclaimed mid/side processor, Midside, to just the essentials: mid/side matrixing, gains, monitoring, & metering — all in a simple, lightweight package. And, because we love M/S processing so much at Goodhertz, we decided to make Midside Matrix free for everyone! Tell your friends (Twitter / Facebook).
