We've built an analyzer VST! It's called VISION 4X.
We have worked with various visual analyzers for over 20 years and they've helped us greatly to understand our sound. Especially when starting out in an imperfect room (i e almost every room) it's really helpful to use analysis and reference. What is it about this track I love that makes it sound so good? And how does my track compare? Do I have enough bass? We used a lot of different ones, and had always wanted to see certain features and functionalities combined, and so we finally set out to build our own plug-in. It's been really exciting and educational making it with Excite Audio.
VISION 4X Is now available at Plugin Boutique.
