Essential Mixing Tips for Aspiring Audio Engineers

Understanding the Difference Between Mixing and Mastering

One of the most crucial aspects of becoming a proficient mix engineer is understanding the clear distinction between mixing and mastering. Many beginners make the mistake of trying to achieve a mastered sound during the mixing phase, which can lead to frustration and subpar results.

The Mixing Phase

Mixing is the process of balancing individual tracks, adjusting levels, panning, EQ, compression, and effects to create a cohesive and pleasing overall sound. During this stage, you're working with the raw recorded tracks and shaping them into a polished production.

The Mastering Phase

Mastering, on the other hand, is the final step in audio post-production. It involves preparing and transferring the final mix to a data storage device (the "master"), from which all copies will be produced. Mastering engineers work on the stereo mix as a whole, making final adjustments to ensure consistency across an entire album and optimizing the sound for various playback systems.

Why This Distinction Matters

When you listen to your favorite professionally produced tracks, you're hearing the result of both mixing and mastering. It's essential to recognize that the raw mix before mastering might sound quite different from the final product. This understanding is crucial for several reasons:

1. Realistic Expectations: By acknowledging the difference, you can set more realistic goals for your mixes and avoid the frustration of trying to match the loudness and polish of a mastered track.

2. Proper Referencing: When using reference tracks, it's important to adjust their volume to match your unmastered mix. This allows for a more accurate comparison of elements like balance and EQ, rather than being misled by the increased loudness of a mastered track.

3. Preserving Dynamics: Trying to achieve mastering-level loudness during the mixing stage can lead to over-compression and a loss of dynamic range, ultimately hurting the quality of your mix.

4. Focus on Mix Elements: By concentrating on mixing rather than trying to master simultaneously, you can dedicate more attention to crucial aspects like balance, clarity, and space within your mix.

Practical Tips for Mixing with Mastering in Mind

1. Leave Headroom: Aim for a mix that peaks around -6 to -8 dB. This gives the mastering engineer room to work without running into digital clipping.

2. Use Reference Tracks Wisely: When referencing commercial tracks, lower their volume to match your unmastered mix. This allows for a more accurate comparison of mix elements.

3. Focus on Balance: Concentrate on achieving a great balance between all the elements in your mix. This is more important than trying to make your mix as loud as possible.

4. Avoid Over-Processing: Don't apply heavy compression or limiting on your master bus in an attempt to make your mix louder. These decisions are best left for the mastering stage.

5. Check Your Mix on Multiple Systems: Before sending your mix off for mastering, listen to it on various playback systems to ensure it translates well across different environments.

Learning Your Plugins Inside and Out

One of the most valuable skills a mix engineer can develop is an intimate knowledge of their tools. This goes beyond simply understanding what each plugin does; it's about knowing exactly how each one affects the sound and when to reach for it in any given situation.

The Importance of Plugin Familiarity

1. Efficiency: When you know your plugins well, you can work faster and more intuitively, spending less time searching for the right tool and more time making creative decisions.

2. Precision: Intimate knowledge of your plugins allows you to make more precise adjustments, leading to better-sounding mixes.

3. Creativity: Understanding the full capabilities of your tools can inspire new and creative ways to use them, potentially leading to unique sounds and mixing techniques.

Strategies for Learning Your Plugins

1. Dedicated Practice Sessions: Set aside time to experiment with each plugin individually. Load up various types of audio material (drums, vocals, bass, etc.) and explore how the plugin affects each.

2. Create Mental Maps: As you experiment, try to build mental associations between specific plugins and their effects on different types of audio material.

3. Comparative Analysis: Compare similar plugins (e.g., different compressors) to understand their unique characteristics and when you might choose one over another.

4. Read the Manual: While it might seem tedious, reading the plugin manual can reveal features and functionalities you might otherwise overlook.

5. Watch Tutorials: Many plugin developers and experienced engineers create in-depth tutorials that can provide valuable insights into using specific plugins effectively.

Examples of Plugin Knowledge in Action

Let's look at some specific examples of how deep plugin knowledge can inform your mixing decisions:

Compressors

• 1176 (Blue Stripe): Known for aggressive saturation and a pronounced mid-range push. Ideal for adding excitement to drums or vocals that need to cut through a mix.

• 1176 (Black Face): Slightly softer on the top end compared to the Blue Stripe, with a less aggressive mid-range. Good for taming transients without drastically altering the overall tone.

• LA-2A: Offers smooth, transparent compression. Excellent for vocals and bass, but less suitable for material with fast transients due to its slower attack time.

• SSL G-Bus Compressor: Great for gluing elements together, particularly effective on the drum bus or the entire mix bus for cohesion.

EQs

• Pultec EQP-1A: Famous for its ability to simultaneously boost and cut at the same frequency, creating a unique tonal shaping. Excellent for adding air to vocals or body to kicks.

• SSL E-Series EQ: Known for its musical high-end boost and versatile mid-range controls. Great for surgical EQ moves without sounding harsh.

• API 550: Offers a distinctive, punchy sound, particularly good for adding presence to drums and guitars.

Reverbs

• Lexicon 480L: Renowned for its lush, expansive sound. Ideal for creating depth in a mix without muddying the original source.

• EMT 140 Plate: Delivers a dense, bright reverb that can add excitement to vocals and snares.

• Eventide Blackhole: Perfect for creating otherworldly, non-realistic spaces that can add unique character to a mix.

Building Your Mixing Toolkit

As you become more familiar with your plugins, you'll start to develop go-to combinations for specific mixing scenarios. For example:

• For a punchy, in-your-face vocal: 1176 (Blue Stripe) for aggressive compression, followed by a Pultec EQP-1A for air and presence, and a touch of EMT 140 plate reverb for depth.

• For a fat, room-filling kick drum: API 550 EQ to enhance the fundamental and click, followed by an SSL G-Bus Compressor for punch, and a small amount of Lexicon 480L reverb to create space.

• For a wide, atmospheric pad: Eventide Blackhole reverb for an expansive sound, followed by a gentle high-pass filter using an SSL E-Series EQ to prevent low-end buildup.

Remember, these are just examples. The key is to experiment and find combinations that work for your specific mixing style and the genres you work with most frequently.

Setting Clear Goals for Your Mix

One of the most crucial aspects of successful mixing is having a clear vision for what you want to achieve. Without a defined goal, it's easy to get lost in the details and lose sight of the bigger picture.
