The #10 Key to Clean, Professional Audio: EQ (The Swiss Army Knife of Audio)

Today, we’re diving into Key #10 for getting clean, clear, and professional audio from your recordings.

It’s called EQ — short for equalization.

And if you’ve heard me say this before, it’s worth repeating:

That’s because EQ, when used well, can do almost anything. Not just shaping tone, but subtly fixing problems, enhancing clarity, adding warmth, or removing harshness.

For many people, EQ seems mysterious. However, once you understand what it really does, everything starts to fall into place.

EQ Isn’t Just About Tone

Most beginners think EQ is only about changing the sound of your voice. Perhaps adding brightness or reducing some of the boominess.

But EQ goes deeper than that.

Think about this: what does the Normalize effect do?

It raises or lowers the overall volume of a track to hit a specific peak level.

Now think about EQ. It’s basically a volume control that lets you adjust specific frequency ranges. So, if you increase or decrease the volume of every frequency in your audio, you’re technically doing the same thing as Normalize.

That’s a big realization.

In fact, I explained this in one of my YouTube videos — and a viewer commented:

If this didn’t quite click yet, read that part again. It’s a lightbulb moment for a lot of people.

What’s the Real Goal of EQ?

We’re not trying to replace Normalize with EQ. That was just an example.

The real purpose of EQ is to:

But what exactly are “good” and “bad” parts?

• The good bits are the frequencies that make your voice sound clear, crisp, warm, or present, in a way that’s smooth and pleasant to listen to.

• The bad bits are the frequencies that cause harshness, muddiness, boxiness, or nasal tones — things that distract or irritate the listener.

With EQ, we boost the good and cut the bad.

For example:

• Want more clarity or crispness? Slightly boost the higher midrange (around 3–6 kHz).

• Want a bit more depth or fullness? Gently increase the low-mid frequencies (around 100–200 Hz).

• Need more air or brightness? Try boosting above 10 kHz — but gently.

On the flip side:

• If your voice sounds harsh, it could be a spike around 3–5 kHz.

• Muddiness often lives around 200–400 Hz.

• Boxiness might show up around 600–800 Hz.

• Nasal sounds are usually in the 800–1200 Hz range.

Once you know what to listen for — and which frequency range affects which aspect of your voice — EQ becomes an incredibly powerful tool.

(The frequency range I mentioned above is not something rigid; it depends on a particular piece of recording)

Why EQ Can Be Hard to Master

Here’s the honest truth:

That’s why EQ plugins like FabFilter Pro-Q3 or Q4 are expensive and highly regarded.

They give engineers more control, but they also assume the user knows what they’re doing.

It takes time to train your ears. You have to listen, compare, test, and refine.

Two Ways to Get the Right EQ for Your Voice

If you’re serious about getting better at EQ, you have two clear options:

1. Learn It Yourself

Start with a Vocal EQ Chart — it gives you a visual map of what each frequency range typically controls. It won’t make you an expert overnight, but it’s a great first step.

Combine that with critical listening and lots of practice, and your skill will grow over time.

2. Get Expert Help

If you don’t want to spend months figuring it out yourself — or if you just want a shortcut to sounding your best — you can get a custom EQ tailored for your voice.

I offer that service through Patreon, where I listen to your sample, analyze the frequency content, and send back an EQ setting that suits your tone, mic, and purpose.

For many voice-over artists and narrators, having one good EQ setting made the difference between sounding like a beginner… and sounding like a pro.

Here's a screenshot of an email conversation with a custom EQ I created for a client, and it completely transformed their voice.
