Frequently asked questions
Which presets are included?
Flat, Bass boost, Treble boost, Vocal / podcast, Loudness, Radio, Classical, Electronic and Acoustic.
What does Prevent clipping do?
Boosting bands can push peaks past full scale and distort. The tool measures the result and lowers the level just enough when needed.
Can I hear changes while I adjust?
Yes. The preview follows the sliders while it plays, and Bypass switches to the original for a quick A/B comparison.
Can an equalizer remove background noise?
Not really. An EQ changes the tonal balance; cutting a band can soften rumble or hiss in that range, but it is not a noise remover.
Are my files uploaded?
No. The EQ is applied in your browser.
