Many of you already use this technique as part of your everyday mixing routine, but I’m always surprised at the number of FL Studio user who don’t. I will listen to their mixes, which are often very good, but they lack separation, width, and depth. If you aren’t using MID / SIDE processing in your mixes, then now is a good time to give it a try. I’m sure you will be pleased (just as I was) the first time you hear it.

What is MID / SIDE processing?

Probably the simplest and best explanation that I’ve read was written by by  on his site Subaqueous Music. He writes:

Mid/Side processing works by decoding a stereo signal into two components. The ‘Mid’ channel contains just the information that appears in both the left and right channels. In other Words it’s the Mono signal.  The ‘Side’ channel contains all the information that differs between the left and right channels. In other words, this is the sounds only on the sides and no where else. Once encoded into M/S, these two signals can be processed completely separately.

As confusing as all of that sounds, we can easily achieve this FL Studio by using using stock plugins provided in your copy of FL Studio. There is no need to buy expensive stereo imaging plugins or EQs to achieve the results you are looking for.

How do you do it?

How to create MID/SIDE processing from scratch:

1. Label any mixer channel ‘MID’. Now label any mixer channel ‘SIDE’
2. Insert Fruity Stereo Shaper into ‘MID’ Effect slot
3. Select Preset: ‘Mid – aSide splitter’ from Stereo Shaper plugin
4. Sidechain MID to SIDE
5. Select any mixer channel you wish to process and route to the MID mixer channel

How does is sound? (headphones on please)
Check out the demo below to get an idea.


0:00 – 0:16 (MID / SIDE OFF)
0:16 – 0:33 (MID / SIDE ON)

The DEMO loop is purposely exaggerated so that you can better hear how MID/SIDE processing affects certain frequencies. I was’t going for a masterful mix here.
