Mastering Mid/Side Processing in Audio Production

Jul 29, 2023

In the realm of audio production, there's an array of tools and techniques at your disposal. Among these, mid/side processing has emerged as a powerful strategy for managing the depth and breadth of a mix. As its name implies, this method involves separate manipulation of the stereo, or mid/side, components of a sound. By providing nuanced control over the stereo image, mid/side processing allows for a balanced enhancement of a mix's perceived width and depth.

Introduction to Mid/Side Processing

Before diving into the practical application of this method, let's set the stage with a brief introduction to mid/side processing. In essence, it's a technique used in audio mixing and mastering that can aid you in managing the space within a mix without disturbing frequencies or resorting to potentially damaging techniques such as cutting away EQ.

Let's explore a simple example. Picture a piece of music where the piano isn't standing out as much as you'd like. Mid/side processing could provide a solution, enabling you to adjust the stereo components of the piano sound to bring it to the fore, while keeping the rest of the mix intact.

Harnessing the Power of Mid/Side Processing

To illustrate the process, we'll use a tool called Mid Side Split in an audio software known as Bitwig. While this specific tool is just one of many options, the principles we'll discuss are universal and applicable across different platforms and tools.

Start by duplicating your existing layer. This offers a straightforward comparison before and after applying mid/side processing. With your original track muted, the stage is set to delve into the intricacies of mid/side manipulation.

In this scenario, the piano part will be the primary focus. By reducing its spatial occupancy in the stereo field and focusing on the mid-range elements, the piano's presence in the mix can be accentuated. Small tweaks here can result in a pleasingly noticeable 'thwack' in the mid content and can help highlight the piano's attack, making it sound tighter and more impactful.

Exploring Further Applications

Once you're happy with the adjustments to the piano, you can carry the same principles over to other elements of the mix. For instance, the bass element could be isolated to mono by completely removing the sides. This approach sharpens the bass sound, giving it a distinct presence in the mix.

Next up are the Supersaw leads. By adding the Mid/Side split, the high version can be made purely sides. Initially, this adjustment might make the sound feel a bit peculiar. But, once all elements are brought back together, the coherence of the mix shines through.

Concluding the Process

For the final stage, copy the processed version to another synth part. Here, we're aiming to increase the stereo field, but without making it purely sides. The outcome? Each component of the mix stands out, adding a sense of depth and clarity. Yet, they all still sound coherent, like one part playing the same theme.

In conclusion, mid/side processing serves as an invaluable tool for audio production enthusiasts. It's an effective way to manage the stereo image and bring a mix to life. With this guide, you're one step closer to mastering the art of mid/side processing, setting you on the path to create high-quality, immersive audio mixes.
