A Practical Approach to Vocal EQ in 10 steps
Because every voice is different, there are no universal EQ presets that guarantee great results.
The most reliable method is to start neutral, listen critically, and make adjustments based on what you hear.
The steps below outline a solid workflow for shaping vocal tone effectively.
Steps:
1. Start with a flat EQ curve. Do not rely on any EQ preset or curve you found online. Always remember that sometimes a non-flat response may already exist due to mic characteristics and its inherent tonal coloration.
2. [Low Cut <60Hz] Roll off the low end as it typically doesn't hold any useful vocal content. Instead, it can contain unwanted rumble, mic stand noise etc. In some cases, you might find it useful to rise the cut-off frequency up to 90Hz.
3. [120Hz] Boosting around 120Hz reinforces low-mid energy, may ad warmth but may cause boominess if boosted too much. Cutting it reduces low-mid body and can make the voice sound thin, even too thin if overdone.
4. [300-600Hz] Boosting this area may cause boxiness(*), especially in booth recordings. A subtle cut in this region usually mitigates the issue.
(*) Audio engineers often use the term “boxy” to describe a vocal or instrument tone that has an exaggerated midrange resonance, typically in the 300–600 Hz region. It sounds as if the audio is coming from inside a small wooden box—(sometimes dull, hollow, congested, and lacking clarity.)
5. [1-2kHz] Usually a slight cut here is helpful, since boosting can make vocals sound nasal. Depending on the nature of the singer's voice and the mic choice you'll have to fine tune this area accordingly. Boosting too much can make vocals harsh rather than just nasal.
6. [4kHz] This area is more commonly associated with presence and aggressiveness. While nasal overtones in this region are less universal, subtly cutting 4kHz may reduce harshness or glare, not just nasality. If, after cutting slightly the 1-2kHz range, you still notice nasal overtones, try a subtle cut on the 4kHz area as well.
7. [5kHz] Boosting around 5kHz enhances vocal presence and brings the voice forward in the mix, especially if the recording is already dull; however, be cautious as it can amplify sibilance ("S" and "T" sounds) and make everything more "hissy". A subtle cut in this region can reduce harshness while maintaining clarity, particularly useful if the vocal sounds too bright or fatiguing to the ear.
8. [6–8 kHz] This range adds clarity, definition, and intelligibility to the vocal, helping consonants and articulation "cut through" the mix. Boosting can make the vocal more present and detailed, but excessive boosts may accentuate sibilance and create a harsh, edgy, or fatiguing tone. A subtle cut can tame harshness without dulling overall brightness. If sibilance persists after adjusting 5 kHz, use gentle EQ adjustments in this band instead.
9. [8–12kHz] Boosting this range enhances brightness, clarity, and the perception of detail. Over-boosting can lead to exaggerated brittleness, or a hyper-detailed sound. Cutting this range reduces high-end sharpness but may dull the vocal if overdone.
10. [12–16kHz] Often called “air” range. Boosting this range adds airiness, openness, and a sense of space. Too much boost can create an unnatural, hyped top end or introduce hiss from the recording environment. Cutting this area is rarely necessary unless correcting harsh, overly bright recordings.
General advice: Always EQ while listening in context with the mix, not soloed, for best results. This avoids the common trap of over-EQing isolated vocals.
Important Note: The frequency ranges and suggestions outlined in this guide are starting points, not absolutes. Every microphone has its own tonal character, and every voice is unique—shaped by gender, age, tone, and technique. Use these steps as a framework to train your ear, then adapt based on what you actually hear. Trust your listening judgment over any preset frequency.
