Frequency Guide for Vocals
Chest & Body
The fundamental warmth of the voice lives here. Too much makes vocals boomy and muddy; too little makes them thin. High-pass around 80-100 Hz to remove rumble without losing weight.
Boxiness Zone
Excess energy here creates a boxy, nasal, or honky quality. A gentle 2-3 dB cut around 300-400 Hz often cleans up male vocals significantly.
Midrange Presence
This range gives vocals body and fullness. Be careful — too much around 800 Hz-1 kHz can sound hollow, while boosting 1-2 kHz adds clarity and forward placement.
Presence & Intelligibility
The critical range for vocal clarity and intelligibility. Boosting 3-5 kHz brings the vocal forward in the mix. Overdoing it creates harshness and listener fatigue.
Sibilance Zone
S, T, and F sounds concentrate here. De-essers typically target 5-8 kHz. Surgical cuts can tame harsh consonants without dulling the overall vocal tone.
Air & Sparkle
A gentle shelf boost above 10 kHz adds airiness and sheen. This is the "expensive" sound in modern pop and R&B vocals — use it tastefully.
EQ Tips
- High-pass at 80-100 Hz with a 12-18 dB/oct slope to remove low-end rumble, mic handling noise, and proximity effect buildup.
- Cut 2-4 dB around 300-400 Hz to reduce boxiness — sweep slowly with a narrow Q to find the worst offender before cutting.
- Boost 2-3 dB around 3-5 kHz for presence, but check for harshness first. If the vocal is already bright from the mic, skip this.
- Use a de-esser targeting 5-8 kHz before your main EQ chain. Aim for 3-6 dB of reduction on the harshest sibilants only.
- Add a gentle shelf boost of 1-2 dB above 10 kHz for air — but only after compression, which can emphasize high-frequency artifacts.
Compression Tips
- Start with a ratio of 3:1-4:1, attack of 10-20 ms, and release of 40-80 ms for general vocal control. Aim for 3-6 dB of gain reduction on peaks.
- Use serial compression: a gentle compressor (2:1, 3-4 dB GR) followed by a faster limiter (8:1+, catching only the loudest 1-2 dB) gives transparent control.
- For rap and aggressive vocals, try faster attack (1-5 ms) and higher ratio (6:1-8:1) for an upfront, in-your-face sound.
- Automate the vocal level before compression — evening out the biggest jumps lets the compressor work more musically instead of pumping.
- Parallel compression with a heavily squashed signal (10:1, fast attack) blended at 20-30% adds density without killing dynamics.
Common Mistakes
Over-compressing and killing dynamics
Slamming vocals with 10+ dB of gain reduction makes them sound lifeless and flat. The emotional peaks and valleys of a performance are what connect with listeners — preserve at least 4-6 dB of dynamic range.
Not using automation alongside compression
Compression alone cannot handle the 15-20 dB dynamic range of a typical vocal take. Ride the fader (or draw automation) to level out phrases before they hit the compressor.
Adding too much reverb to mask problems
Drowning vocals in reverb hides pitch issues and timing problems temporarily, but pushes the vocal behind the mix. Fix the source problems first, then use reverb for space.
Ignoring proximity effect from the recording
If the singer was too close to a cardioid mic, there will be excessive bass buildup below 200 Hz. No amount of mixing magic replaces a proper high-pass to clean this up.
Vocals in the Full Mix
Vocals need their own dedicated frequency pocket — typically around 1-5 kHz — where no other element competes for attention. Side-chain or duck competing instruments (guitars, synths, keys) in that presence range by 1-3 dB when the vocal is active. The vocal should sit on top of the mix, not buried inside it, with reverb and delay providing depth without pushing it backward.
The quick answers
What is the best compressor ratio for vocals?
For most genres, 3:1 to 4:1 works well as a starting point. Pop and R&B often benefit from heavier compression (4:1-6:1), while acoustic and jazz vocals sound more natural at 2:1-3:1. The key is to listen — if you can hear the compressor working, back off.
Should I EQ before or after compression on vocals?
Both approaches work, but EQ before compression is more common for vocals. Cutting problem frequencies first (like 300 Hz boxiness) means the compressor reacts to a cleaner signal. You can always add a second EQ after compression for tonal shaping.
How do I make vocals sound professional without expensive plugins?
Focus on gain staging, proper automation, and subtractive EQ. Most stock DAW compressors and EQs are more than capable. The biggest quality leap comes from volume automation — spending 30 minutes riding the vocal fader makes more difference than any plugin.
How loud should vocals be in the mix?
In most pop, hip-hop, and R&B, vocals sit 1-3 dB above the next loudest element. In rock, they may sit more level with the instruments. Use reference tracks in the same genre and A/B frequently to calibrate your ears.
