See the Curves of an Outboard EQ Using a Frequency Analyser

Introduction

See the Curves of an Outboard EQ Using a Frequency Analyser – Equalization, or EQ, is a fundamental tool in audio production. It allows us to shape the tonal balance of audio signals by boosting or cutting specific frequency ranges. But how can we visualize what’s happening when we adjust an outboard EQ? The answer is: with a frequency analyser.

What is a Frequency Analyser?

A frequency analyser is a device that displays the spectral content of an audio signal. It shows how much energy is present at each frequency, allowing us to see the ‘shape’ of the sound. When used in conjunction with an EQ, it can provide a visual representation of the changes we’re making.

Steps to Visualize EQ Curves

Step 1: Connect Your Equipment

First, you’ll need to connect your outboard EQ and frequency analyser to your audio interface. The exact method will depend on your specific gear, but typically, you’ll send an audio signal from your interface to the EQ, then from the EQ to the analyser, and finally back to the interface.

Step 2: Generate a Test Tone

Next, generate a test tone in your digital audio workstation (DAW). A pink noise signal is ideal for this purpose, as it contains equal energy at all audible frequencies, providing a ‘flat’ baseline for your EQ adjustments.

Step 3: Adjust Your EQ

Now, start adjusting your EQ. As you boost or cut frequencies, you’ll see the changes reflected in the frequency analyser’s display. This allows you to see exactly what your EQ is doing to the signal.

Step 4: Analyze and Adjust

Use the visual feedback from the frequency analyser to guide your EQ adjustments. If you see a frequency range that’s too prominent, you can cut it on the EQ; if a range is lacking, you can boost it. The analyser provides a way to confirm what your ears are telling you.

Setting Up in the Digital Audio Workstation (DAW)

Here are more detailed steps on how to set up your outboard EQ and frequency analyser in your DAW:

Step 1: Connect Your Equipment

First, you’ll need to connect your outboard EQ and frequency analyser to your audio interface. The exact method will depend on your specific gear, but typically, you’ll send an audio signal from your interface to the EQ, then from the EQ to the analyser, and finally back to the interface.

Step 2: Set Up Your DAW

Next, open your DAW and create a new project. You’ll need to set up a track to send audio to your outboard EQ. This is usually done by creating a new audio track, setting its output to the appropriate output on your audio interface, and enabling the track for recording.

Step 3: Generate a Test Tone

Now, generate a test tone in your DAW. Most DAWs have a built-in function to generate test tones. A pink noise signal is ideal for this purpose, as it contains equal energy at all audible frequencies, providing a ‘flat’ baseline for your EQ adjustments.

To generate a pink noise signal in your DAW, you can usually find this option in the menu under “Generate” or “Insert”. Select “Pink Noise” and adjust the duration and level as needed.

Step 4: Route the Test Tone to the EQ

Next, you’ll need to route the test tone to your outboard EQ. This is done by setting the output of the track with the test tone to the same output on your audio interface that is connected to the EQ.

Step 5: Adjust Your EQ

Now, start adjusting your EQ. As you boost or cut frequencies, you’ll see the changes reflected in the frequency analyser’s display. This allows you to see exactly what your EQ is doing to the signal.

Step 6: Analyze and Adjust

Use the visual feedback from the frequency analyser to guide your EQ adjustments. If you see a frequency range that’s too prominent, you can cut it on the EQ; if a range is lacking, you can boost it. The analyser provides a way to confirm what your ears are telling you.

Remember, the goal is not necessarily to achieve a flat response, but rather to shape the sound to your liking or to fit the needs of your mix. Happy mixing!

Conclusion

Using a frequency analyser with an outboard EQ is a powerful technique for shaping your audio signals. It provides a visual guide to the changes you’re making, helping you to craft the perfect sound. So, the next time you’re reaching for that EQ knob, consider hooking up a frequency analyser and see what it can reveal about your sound.
