Equalizer
A ten-band equalizer that doesn’t clip.
Antify has a built-in 10-band equalizer from 32 Hz to 16 kHz — in the browser, in the Android app and in the programs for Windows and Linux. Try it below without an account; further down you’ll find what it can do and what each band does to the sound.

Hear the difference.
The same 10-band equalizer as in the app — try it here without an account. The demo sound is generated right in your browser.
The demo needs JavaScript to play.
The demo uses the same band frequencies, filter types, range and auto-preamp formula as the app. It shows nine of the 27 presets; the sound is generated synthetically in your browser, nothing is downloaded.
What the equalizer can do
- Bands
- 10 — 32, 64, 125, 250, 500 Hz, 1, 2, 4, 8 and 16 kHz
- Range
- ±12 dB per band, in 0.5 dB steps
- Filters
- Shelving filters at 32 Hz and 16 kHz, eight peaking filters in between
- Preamp
- ±12 dB manual, plus auto preamp (on by default)
- Presets
- 27 built in, plus your own under a name you choose
- Comparison
- A/B against the original (key B), reset (R), undo (Ctrl+Z)
- Display
- Frequency curve of your setting and a live spectrum during playback
- Saving
- The active curve follows your account to other devices; custom presets are stored on the device and can be exported and imported as a file
Auto preamp: louder isn’t better
Boosting bands makes the signal louder — and a louder signal almost always sounds “better” at first, even when the setting isn’t. Strong boosts can also clip.
Auto preamp therefore lowers the preamp to match the curve: by about 70 % of the largest boost plus a small allowance for neighbouring boosts, rounded to 0.5 dB and by at most 9 dB. Cuts are left alone. A limiter sits at the end of the chain as well. So when you switch A/B, you compare the sound, not just the volume.
The 27 built-in presets
Presets are starting points, not recipes. They cover genres, devices and listening situations — from “Kopfhörer” (headphones) and “Handy-Lautsprecher” (phone speaker) to “Night” for quiet listening and “Podcast / Stimme” (voice). Save your own setting under a name of your choice; it then appears in the list under “Eigene” (custom). Preset names are shown as they appear in the app, which is in German.
Which band does what?
The bands are one octave apart. Where things sit in a song depends on the recording — treat the table as orientation, not law.
| Band | Range | What you hear |
|---|---|---|
| 32 Hz | Sub-bass | Felt more than heard: deep 808s, organ, rumble. Small speakers reproduce very little here. |
| 64 Hz | Bass | The push of kick and bassline. Too much of it booms. |
| 125 Hz | Upper bass | Fullness and punch. Music gets thick here quickly. |
| 250 Hz | Low mids | Warmth — or mud. A slight cut makes a lot of music clearer. |
| 500 Hz | Mids | Body of voices and instruments; too much sounds hollow or boxy. |
| 1 kHz | Mids | Presence and intelligibility, nasal when overdone. |
| 2 kHz | Upper mids | Attack of guitar and snare. The ear is sensitive here — small steps. |
| 4 kHz | Presence | Closeness of the voice, definition. Too much turns harsh fast. |
| 8 kHz | Treble | Cymbals, sibilance (s sounds), detail. |
| 16 kHz | Air | “Air” above everything. Subtle, and very dependent on headphones and hearing. |
Four rules that almost always help
- Cut first, then boost. Removing what bothers you needs less boosting — and less headroom.
- Work in small steps: 2 to 3 dB is clearly audible. ±12 dB is for exceptions.
- Check with A/B. After a few minutes your ear gets used to any setting — comparing with the original brings you back.
- Tune for the device, not the song. A curve that corrects your headphones suits every song; per-song recipes need changing all the time.
