What is an audio equalizer?

An equalizer (EQ) is a tool that allows you to adjust the volume of specific frequency ranges in audio. It lets you boost or cut bass, midrange, and treble frequencies to enhance or correct sound quality.

What's the difference between 3, 5, and 10 band EQ?

3-band EQ offers basic control (bass, mid, treble). 5-band provides more precision with additional frequency points. 10-band gives professional-level control with detailed frequency adjustment across the entire audio spectrum.

What audio formats are supported?

MP3, WAV, OGG, M4A, FLAC, and most common audio formats. The tool uses your browser's audio decoding capabilities.

How do I use the presets?

Select a preset from the dropdown menu. Each preset is optimized for specific music genres or purposes. For example, 'Bass Boost' increases low frequencies, 'Vocal Enhance' emphasizes speech frequencies.

Can I create custom EQ settings?

Yes! Adjust any slider to create your own EQ curve. The changes apply in real-time so you can hear the effect immediately. Use 'Reset EQ' to return all bands to neutral (0 dB).

What does each frequency band control?

Lower frequencies (31-125 Hz) control bass and rumble. Mid frequencies (250Hz-4kHz) affect vocals and most instruments. High frequencies (8kHz-16kHz) control brightness, clarity, and air.

Is my audio file uploaded to a server?

No! All processing happens locally in your browser. Your audio never leaves your computer, ensuring complete privacy and security.

Can I download the equalized audio?

Yes! After applying EQ, click 'Download Processed Audio' to save the result. The output maintains the original audio quality with your EQ adjustments applied.

Why should I use EQ on my audio?

EQ helps fix recording issues (reduce rumble, fix muddiness), enhance certain instruments or vocals, match sound across multiple tracks, or shape audio to suit different playback systems (headphones, speakers, car audio).

What's the best EQ setting?

There's no universal 'best' setting - it depends on your source audio and desired result. Start with presets, then fine-tune. Remember: less is often more. Subtle adjustments usually sound more natural than extreme boosts or cuts.
