In the world of audio mixing, developing a sharp ear is as crucial as having the right tools. In this week's video, I explore how blind testing can help refine your auditory skills. This method is not just about listening but understanding and identifying sonic differences with precision.
Why Blind Testing Matters
Audio engineering presents a landscape full of nuanced decisions. With countless plugins and compressor options, choosing the right one can be daunting. Blind testing emerges as an essential technique for making these decisions with clarity. What I love about this approach is not just the ability to discern differences but also to confront and eliminate biases—those moments when a favorite plugin's allure clouds objective judgment.
Setting Up for Success
To start, you'll need a practical tool, like the Hofa 4U Plus Blind Test plugin, which is free and incredibly effective. Here's a breakdown of the process:
1. Prepare Your Tracks
- Duplicate the vocal channel and eliminate existing compression.
- Use different compressors, such as an 1176 and an LA-2A, along with a dry track to compare the unprocessed sound.
- Load the Blind Test plugin across these channels for randomization.
2. Test and Observe
- Cover up the meters with the plugin to maintain the test's integrity and begin a blind A/B/C comparison.
- Note down your observations.
Analyzing Compressor Characteristics
Understanding compressor characteristics is where experience meets keen observation:
Using the 1176
I often choose an 1176 for its fast release and a quick attack, seeking a balance around 5 dB of gain reduction. It brings a mid-forward sound with a touch of distortion—offering that exciting, snappy texture where the back ends of phrases pop forward.
Exploring the LA-2A
The LA-2A, with its straightforward gain reduction knob, offers a smoother, more rounded compression. It handles transitions beautifully, making it less about snapping and more about fluid evolution.
Combining Compressors for Impact
Sometimes, combining different compressors, like using an LA-2A for its smoothing capabilities alongside an 1176's energetic snap, achieves the desired vocal impact. A Distressor can bring in fast attack and release settings akin to the 1176, adding complexity and depth.
Push the Limits
If discerning these differences feels challenging, try pushing compressors to their limits. Exaggerating settings—formerly unheard compression amounts—can accentuate characteristics, training your ear to recognize subtler changes later.
The Drum Test
Switching focus to another domain—drum tracks—offers another realm of discovery. Varying compressors like the Fairchild tube compressor against a VCA model like the 33609 reveals differing attack and release impacts on transient clarity.
- Noticed difference: The Fairchild lets transients like snare hits pierce through, whereas the 33609 softens them, affecting overall mix punchiness.
Reinforcing Growth and Objectivity
Blind testing is about more than discerning sound—it's about honing your craft without bias. When stepping away from preferences and confronting truths, you learn what truly works in your mixes.
For those ready for a higher challenge, attempt blind testing with EQs—a deeply nuanced but rewarding pursuit.
In closing, blind testing isn't just a skill—it's a commitment to growth and a journey towards excellence. By consistently applying this technique, you'll train your ears and broaden your professional scope.
