How the 10-Band Graphic Equalizer Works
A graphic equalizer shapes audio frequency response by applying calibrated parametric filter nodes (Biquad peak and shelving filters) across standard octave bands from 32 Hz up to 16 kHz. By adjusting these bands, you can compensate for speaker limitations, add warmth to thin recordings, or remove harsh vocal sibilance.
| Frequency Band | Sound Characteristic | Recommended Adjustment |
|---|---|---|
| 32 Hz & 64 Hz | Sub-bass, 808 rumbles, kick drum thud | Boost +4 to +8 dB for hip-hop and EDM; cut for clean voice |
| 125 Hz & 250 Hz | Bass warmth, snare body, vocal chest resonance | Cut -2 to -4 dB if the track sounds muddy or boomy |
| 500 Hz & 1 kHz | Mid-range body, guitars, horn sections, vocal fundamentals | Keep near 0 dB; subtle boost brings instruments forward |
| 2 kHz & 4 kHz | Vocal presence, speech intelligibility, snare attack | Boost +3 to +6 dB to make vocals cut through any mix |
| 8 kHz & 16 kHz | High treble air, hi-hat shimmer, acoustic sparkle | Boost +4 to +8 dB for modern crisp studio brilliance |
Frequently Asked Questions
Q: What is a 10-band graphic equalizer?
A 10-band graphic equalizer divides audible sound frequencies into 10 distinct octave bands: 32Hz, 64Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, and 16kHz. Each slider lets you boost or cut that specific frequency range by up to ±12 dB.
Q: How do I boost bass without distortion?
Select the Bass Boost preset or raise the 32Hz and 64Hz sliders by +4 to +8 dB. Our audio engine includes an automatic soft-limiter to prevent harsh digital clipping.
Q: Can I preview my EQ settings before downloading?
Yes! You can play, pause, seek, and adjust any EQ slider in real time to hear instant changes through your headphones or speakers.
Q: Is my audio uploaded to a server?
No! All audio decoding, equalization filtering, and encoding runs 100% locally in your web browser using HTML5 Web Audio API. Your files remain completely private.
