For years, the debate has raged on whether DJs should master their DJ sets before performing them live. Others claim that it is not necessary, but some swear by it. What is the truth? This article will cover all you need to learn about DJ mastering.

General Mastering vs. DJ Mastering

General music mastering involves preparing a polished, final stereo mix for release on various platforms and systems of playback. This involves equalisation, compression, and limiting, as well as finding the perfect balance between loudness, dynamics, and volume.

Mastering for DJ mixes is also called mix sets. A mix set is a sequence of music tracks that a DJ has blended together to create a seamless music flow.

Although a DJ set can be viewed as a stereo mix for mastering purposes, there are significant differences between general mastering and mastering DJ sets. Mastering’s ultimate goal is to ensure that audio sounds great on all devices and playback systems, preparing it for distribution. General mastering is traditionally focused on a natural, tenacious sound that will help the track achieve its full potential across multiple platforms.

Specialised DJ mastering focuses on optimising a mix so that it can be played in a DJ set. It emphasises loudness and punchiness. The goal is to produce a mix that sounds dynamic, cohesive, and intense when used in a DJ set. General mastering and DJ Mastering are different in terms of scope, purpose, and priorities.

Why should DJs master their mixes?

The industry is divided, as we explained at the start of this article. Many DJs, not just the less experienced ones, find mastering their mixes redundant because they have already mastered each track. I don’t understand what you mean by mastering. You could adjust the gain. One user posted in a Reddit forum that the tracks had already been learned.

This argument seems logical, but there’s another side. It doesn’t matter if the tracks that make up a DJ mix were previously mastered. They may not have mastered the same standards. There is no guarantee that the mix will be consistent in terms of loudness, balance and cohesion.

Also, DJ sets—especially those designed for live performances—are played in environments that can be acoustically demanding. This means that small imbalances and nuances (despite the loud environment) may become apparent. It’s not enough to simply blend tracks together to make your set sound loud, dynamic, and polished.

Some might say that it is the DJ’s responsibility to adjust and manage their mix in real-time during a performance. The trick is to ensure that your mix is gain-adjusted properly throughout the mix as you mix. Another Reddit user adds, “This is a skill that every DJ should master.”

We’re not lying, but this is an excellent point. And the truth is, skilled DJs are capable of doing it. Even with the best DJing techniques, there are limitations on what can be done live. A recorded mix can be mastered before a performance to improve the overall sound, balance dynamics, ensure consistency in the set and optimise the mix for different systems. Real-time adjustments can’t achieve these aspects.

In addition, it’s important to remember that DJ sets can be distributed on a variety of platforms, including streaming services such as SoundCloud, Spotify, and Apple Music. It’s important to ensure that the mix is compatible with all platforms and adheres to each platform’s audio standards and requirements.

You must know that mastering your DJ mix isn’t considered essential. It is recommended, however, if you intend to share or use your mix in a professional setting. Mastering is a way to make your mix sound professional, coherent, and loud enough for the intended purpose. This could be streaming, downloading, live performances, etc. Mastering your DJ mix will:

• Make sure your mix is compliant with the audio standards for the platforms you have selected and that it sounds the same across all playback systems.
• Increase the perceived loudness of your mix, without compromising clarity or dynamic range.
• Make your mix stand out from other mixes by focusing on quality and impact.
• Correct any errors or imperfections.
• Improve the overall balance and quality of the mix.
• Strengthen and support your unique creative identity.

The Key Techniques of DJ Mix Mastering

1. First, equipment

You need the right tools before you begin mastering. A DAW is essential, as well as mastering software that will help you along your journey. A DAW allows you to edit, process, and export your mix. Most DAWs come with a standard version of the audio processing tools you need to master your DJ mix, such as a compressor, limiter and equaliser. There are many 3rd-party plugins and mastering instruments that deliver much better results. You can have your mix professionally mastered in a studio by a skilled mastering engineer. However, this may be very expensive.

These prominent tools include

•  Since 2001, iZotope’s flagship mastering suite has become one of the most popular packages in the mastering industry. The 11th edition includes, in addition to the basic features, clarity mode, transient processing and sustain, Stem Focus, and many more. You will have to pay a higher price than other mastering tools.
• FabFilter is a similar source to iZotope for high-quality audio plugins used for recording, mixing, and mastering. The plugins are top-notch and boast a premium sound, along with a host of out-of-the-box features.
• Instant Mastering is iMusician’s online audio-mastering platform, which is incredibly fast and easy to use. It’s tailored for independent artists and labels. The tool is easy to use and offers many presets for different genres. It also allows you to use a reference track.
• LANDR mastering: This AI-driven tool can analyse your tracks and adjust them based on genre, style and other parameters like dynamics, frequency balance and stereo width. It’s easy to use and has a friendly interface.

2. Leave Headroom when Preparing Mixes for Mastering

Lowering the volume is your first step when creating music. This might seem like an odd suggestion, but reducing the output of the mix is crucial to avoid distortion when applying audio processing that would otherwise max out the volume meter.

It is recommended to leave at least 3-6 dB in headroom when mastering a mix for a DJ. The loudest peaks of your mix shouldn’t exceed -6 6dBFS (decibels at full scale), and should be ideally around 3dBFS. If a DJ mix will be played back in lossy format (e.g. MP3, AAC, etc.), then it is best to aim for 3-1 dB of headroom. We may want to aim for a 3-1 dB headroom. This headroom allows some compression to be done during the lossy encoding process. This prevents distortion and clipping.

3. Balance EQ and Frequency

Equalisation (EQ) is the process of adjusting various frequencies in an audio signal, typically the lows and mids, to achieve a desired sonic clarity and balance. The mastering process is incomplete without EQ. It helps remove unwanted frequencies by using subtractive or corrective EQ. This should be the first step in your mixing process. It also allows for smoother transitions from one track to the next by removing unwanted frequencies when one fades out and another fades back in.

Lastly, EQ allows you to customise the sound of your mix. By enhancing EQ, you can achieve a better frequency balance and make your mix sound the way you like it.

4. Compression and Limiting

After applying EQ, you will need to manage your mix’s dynamic range. Compression is an important tool to control the dynamic range and achieve the desired loudness. Compression reduces the difference in volume between the loudest parts and the softest, which results in a more consistent sound. It is usually recommended to use ratios such as 2:1 and 3:1 when compressing audio. Also, try to use slower release and attack times. However, you can experiment until your transients sound as you like.

Limiting is a more aggressive form of compression that establishes the maximum decibel level for a mix. The audio is prevented from going over the limiting dB. This will increase the volume of the mix without adding distortion.

A little tip from us: Don’t use limiters excessively. Over-limiting may result in a sound that is flat, lifeless and possibly distorted. It is important to remember this when DJing, since dynamics can be crucial.

5. Stereo Imaging

Stereo imaging is a term used to describe how the sounds are placed in the imaginary space between the left—and right-side speakers or headphones. The purpose of stereo imaging is to produce a more expansive, dimensional sound. A balanced stereo image will make the mix more natural, spacious, and engaging. This also gives instruments more breathing room, which results in a dynamic listening experience.

It’s often up to the artist whether they choose a wider stereo image or a narrower, more focused one. However, in electronic and club-oriented dance music, a common best practice is to keep low-end frequencies–especially bass and kick–in mono (or narrow) for maximum impact and clarity on large sound systems. At the same time, higher-frequency elements such as synths, pads and effects can also be expanded to create more space and sparkle without affecting the low end.

6. Harmonic Saturation

Harmonic saturation is not often included in mastering resources, but it’s a fairly common technique. This is a controlled, subtle distortion that adds harmonic frequencies to the sound. It gives a mix of character, warmth, and depth. Some say that it “glues“ together different elements of a mix to make it sound thicker.

When mastering a specific DJ mix, saturation can be used to add character and richness. It also softens harsh transients and creates a more consistent sound throughout all tracks.

7. Loudness Control

In our article about mastering for Spotify, we have discussed loudness optimisation in great detail. Loudness optimisation is the process of adjusting an audio file’s volume to a target level, measured in LUFS. This allows for a consistent volume to be played on different devices and tracks. It is important to get your mix loud enough without damaging the dynamic range or adding unwanted distortion.

Loudness goals may vary depending on the distribution channel and format. It is recommended that streaming platforms such as Spotify, YouTube and Apple Music have a target loudness of -14dB integrated LUFS, while CDs should be in the range of -9 dB to -12dB LUFS.

It may be advantageous to use a higher average level for club tracks, such as 6 dB LUFS, to compete with the other tracks during a live performance. The peak level of the track should be kept below to avoid clipping.

Use tools such as Loudness penalty to determine how the loudness of your track is affected by audio requirements for different platforms. This will help you understand how your mix sounds across various services and playback devices. The tool simulates how your mix might be adjusted based on platform-specific loudness standardisation.

8. Revisions and final amendments

This final stage is all about revision. You can take as much time as you need to ensure that your DJ mix is exactly what you want before you send it off to its destination or prepare it for your performance.

Take breaks. The more you listen to and hear your mix, the more your ears will become fatigued. Share your mix with your friends, audio engineers or other DJs and artists. They can give you constructive and unbiased feedback that will help you get the sound and quality you want.
