Stereo Width Control is an Audio Unit plugin that allows you to increase or decrease the stereo width of 4 adjustable frequency bands. Mastering engineers use it to ensure that the bass frequencies of the kick drum and bass instruments stay tightly focused in the centre channel while a keeping spacious stereo image in the mid range frequencies.

Stereo Width Control operates with your choice of 1 to 4 separate bands. Each band has a solo control, used to audition that band on its own while you adjust its frequency range and stereo width setting.

In the lower right is a stereo vectorscope graph that is helpful for visualising the volume and stereo width of your tracks.

NOTE: This app is an Audio Unit plugin that runs inside of host apps such as GarageBand. It does not process audio in standalone mode.

This is a permanent part of my mastering chain as it is so useful for dialing in the perfect locations for various frequencies and creating the right amount of space in the overall mix. Excellent!
