Frequently asked questions

Answers for licensing, quality, and workflow

What is a frequency band equalizer?+
A frequency band EQ is an audio processor that divides the sound spectrum into multiple frequency bands (low, mid, high), allowing you to independently boost or cut specific frequency ranges to shape the tonal balance of audio. Our 7-band parametric EQ gives you precise control over seven strategic frequency points covering the entire audible spectrum.
What do the 7 frequency bands control?+
Sub Bass (60Hz) controls deep low frequencies and rumble; Bass (150Hz) affects low fundamentals and warmth; Low Mid (400Hz) shapes body and presence; Mid (1kHz) controls core presence and clarity; High Mid (2.5kHz) affects definition and consonant detail; Presence (6kHz) controls air and sparkle; Treble (12kHz) affects brightness and high-frequency extension.
What is the Q value and how do I use it?+
Q (Quality Factor) controls the bandwidth of each frequency band. Low Q values (0.1-1) create wide, gentle curves affecting broader frequency ranges - ideal for musical boosts. High Q values (5-10) create narrow, precise curves targeting specific frequencies - perfect for surgical cuts to remove problem frequencies without affecting surrounding areas.
When should I boost vs. cut frequencies?+
Generally, cutting is preferred over boosting to avoid distortion and maintain headroom. Cut unwanted frequencies (rumble, muddiness, harshness) first with narrow Q values, then make subtle boosts to enhance desired characteristics with wider Q values. Cutting also uses less processing power, sounds more natural, and prevents digital clipping.
What EQ preset should I use for my audio?+
Rock preset boosts bass and treble for power and clarity. Pop preset enhances mids and highs for vocal presence. Jazz preset emphasizes warmth and natural tones. Classical preset adds air and detail. Vocal Enhance boosts speech intelligibility. Bass Boost emphasizes low frequencies. Treble Boost adds high-frequency sparkle. Start with the preset closest to your goal and adjust to taste.
How do I use EQ for mixing music?+
Start with flat EQ and identify problem areas by listening critically. Cut muddy low-mids (200-400Hz) to clear up the mix, reduce harshness (2-4kHz) for smoother sound, and add clarity (8-12kHz) for air and detail. Make subtle adjustments (1-3dB) and always A/B compare with bypassed EQ. Use narrow Q for cuts (3-5), wider Q for boosts (0.7-1.5).
Can I save my custom EQ settings?+
Yes, click the Save Settings button to export your EQ configuration as a JSON file. This includes all band frequencies, gain values, Q settings, and master gain. Load saved settings later to apply the same EQ curve to different audio files or projects. You can build a library of custom presets for different instruments, voices, or mixing scenarios.
Does this work with live microphone input?+
Currently, the EQ processes uploaded audio files only, allowing you to load tracks and hear EQ effects during playback. Microphone input support for live processing is planned for future updates, which will enable real-time EQ for live performances, streaming, recording sessions, and voice calls.
How is this different from a graphic equalizer?+
Parametric EQs (like this tool) allow you to adjust frequency center, gain, and Q value for each band, giving you precise surgical control. Graphic EQs have fixed frequency bands with only gain adjustment. Parametric EQs are more flexible for problem-solving and creative sound shaping, while graphic EQs are faster for broad tonal adjustments.
What's the best way to remove muddiness from audio?+
Muddiness typically lives in the 200-500Hz range. Use the Low Mid band (400Hz) with a narrow-to-medium Q value (1.2-1.8) and cut by 2-4dB. You can also try cutting the Bass band (150Hz) by 1-2dB if the muddiness extends lower. Always use your ears and A/B compare - sometimes less is more.
How do I make vocals sound clearer and more present?+
Start by cutting muddiness: Low Mid (400Hz) -3dB with Q=1.5. Then boost clarity: High Mid (2.5kHz) +2-3dB with Q=1.0 for definition, and Presence (6kHz) +2-3dB with Q=0.8 for air. Finally, roll off Sub Bass (60Hz) -8dB with Q=1.0 to remove rumble. Adjust to taste while monitoring the frequency response curve.
What causes harsh or brittle sound and how do I fix it?+
Harshness typically comes from excessive energy in the 2-6kHz range. Use the High Mid band (2.5kHz) and Presence band (6kHz) with narrow Q values (1.5-2.5) and cut by 2-4dB. Start with smaller cuts and increase gradually until harshness is reduced without losing clarity. The visual frequency response curve helps identify problem peaks.

Professional Frequency Band Equalizer for Audio Production

Deep-dive context for AI-generated music

Frequency Band EQ is a professional-grade online equalizer designed for music producers, audio engineers, podcasters, and content creators who demand precise control over their audio's tonal balance. Unlike simple bass and treble controls, our 7-band parametric EQ gives you surgical precision to shape sound across the entire audible spectrum from 20Hz to 20kHz.

The tool features seven strategically chosen frequency bands that target the most important areas of the audio spectrum: Sub Bass (60Hz) for deep low-end control, Bass (150Hz) for fundamental warmth, Low Mid (400Hz) for body and presence, Mid (1kHz) for core clarity, High Mid (2.5kHz) for definition, Presence (6kHz) for air and detail, and Treble (12kHz) for sparkle and brightness. Each band offers independent control over frequency center, gain adjustment from -20dB to +20dB, and Q factor from 0.1 to 10 for precise bandwidth control.

Whether you're mixing music, mastering tracks, producing podcasts, or enhancing video audio, our visual frequency response curve provides real-time feedback showing exactly how your EQ adjustments affect the tonal balance. This visual approach helps you avoid common mixing mistakes like extreme peaks, unnatural dips, or frequency masking between instruments.

The built-in professional presets offer instant starting points for common audio enhancement tasks. Rock, Pop, Jazz, and Classical presets apply genre-specific frequency curves fine-tuned by professional audio engineers. Bass Boost and Treble Boost presets provide enhanced low-end or high-frequency sparkle, while the Vocal Enhancement preset is optimized for speech intelligibility and clarity in podcasts, voiceovers, and dialogue recordings.

Advanced features include save and load functionality for building your personal library of custom EQ presets, master gain control to compensate for overall level changes, and real-time audio processing with zero latency. Upload your audio files to hear EQ changes instantly during playback, making it easy to achieve the perfect tonal balance for your project. The tool exports settings as JSON files, allowing you to apply the same EQ treatment across multiple projects consistently.
