What is mid side compression?
Mid/side compression is a technique used by many pro engineers for increased flexibility when processing stereo material. By encoding a stereo signal from L/R to M/S, it's possible to compress the mono (mid) and stereo (side) elements of the signal independently.
When should you mid side EQ?
Use mid-side equalization to create a wider stereo image on a full mix or individual elements. You can create stereo width by changing the balance between mid and side levels. For example, widen a signal by boosting high frequencies in the side channel or attenuating low frequencies in the mid channel.
Is Mid Side EQ necessary?
Mid/side EQ lets you adjust frequencies in the center of a stereo track separately from the sides, which can be an extremely useful technique for mastering. When used correctly, mid/side EQ gives you additional control over stereo tracks and can even be used to isolate instruments in the mix.
