Processes each microphone signal individually, allows to set a balance/mix between both microphones, and sums them to mono. Can adjust timing between signals. |
 | [![m-s_fader](https://user-images.githubusercontent.com/53377392/93859337-d02f4a00-fcbd-11ea-9455-9bb28fdfc63e.jpg)](https://user-images.githubusercontent.com/53377392/93859434-e937fb00-fcbd-11ea-81e5-b51d3218eab1.png) | [M-S Fader](https://github.com/chkhld/jsfx/blob/master/plugins/m-s_fader.jsfx) | Converts a stereo source to a Mid/Side signal and then fades between 100% Mid and 100% Side signal, or a mix of both. Great to remove the center signal, or to focus in on it. |
 | [![phase_scope](https://user-images.githubusercontent.com/53377392/93859338-d02f4a00-fcbd-11ea-8eb7-362d9b0df257.jpg)](https://user-images.githubusercontent.com/53377392/93859438-e9d09180-fcbd-11ea-8515-8df9d63c0fe0.png) | [Phase Scope](https://github.com/chkhld/jsfx/blob/master/plugins/phase_scope.jsfx) | Visualizes the stereo field of a signal, also commonly known as Goniometer, Vector Scope or Lissajous. Selectable visualization colour and optional freeze-on-pause function. |
