Mastering - Mid/Side EQ

Updated: Dec 21, 2020

Using the mid side mode on an EQ is an effective method of controlling the stereo signal and mono signal independently from one another. Typically, EQ moves are applied on just the sides as the mids are processed through every other EQ and compressor. This stage and the next (mid side compression) are the only stages in which we have independent control over the sides. The most important step for this EQ is to remove any muddy frequencies from the sides using a high pass filter at around 90 – 150Hz. Having information present in the sides below this frequency is extreme potential for phase cancellation causing exaggerated loss of power and clarity. In this same EQ, finding a pleasant frequency band and boosting it can help enhance the stereo imaging of your track.
