Dynamic EQ

Parametric bands, each with optional dynamics

Double-tap to add a bandDrag to move · pinch to change width

Double-tap the graph (or tap + Band) to add a band. Drag a dot to move it, pinch or scroll to change its width.

How to edit audio and video online

  1. Tap Open video or audio and pick a file from your phone or computer.
  2. Trim: drag the amber handles on the timeline, or use the Start/End buttons to nudge by a tenth of a second or jump to the playhead.
  3. EQ: pick a preset or double-tap the graph to add your own bands.
  4. Look (video only): adjust brightness, contrast, saturation and warmth, or choose a preset.
  5. Volume: set the overall level and add a fade in and fade out.
  6. Tap Export and choose video (MP4/WebM) or audio only (WAV), then save or share it.

A real parametric EQ with dynamic bands

The equalizer has up to 12 bands from 20 Hz to 20 kHz. Each band can be a bell, low or high shelf, low or high cut (12, 24 or 48 dB per octave) or a notch. Drag a dot to change frequency and gain, pinch or scroll to change its width (Q), and use the headphones button to solo a band and hear exactly what it is doing.

Bell and shelf bands can also be dynamic: set a threshold, range, attack and release, and the band only reacts when that part of the sound gets loud. It is the same idea studio engineers use to control harsh vocals, sibilance or boomy bass without making the whole mix dull.

Presets to start from

  • Voice clarity and Podcast: cleaner, more present speech.
  • De-ess: softens sharp "s" and "sh" sounds.
  • Tight bass: removes rumble and muddy low end.
  • Air and Music polish: adds sparkle and balance to music.

Export options

  • Video: MP4 or WebM depending on your browser, with your trim, EQ, look and volume applied. It is recorded in real time, so keep the tab open until it finishes.
  • Audio / Audio only: a WAV file rendered instantly. Use it to extract the soundtrack of a video or to save a cleaned-up voice note, podcast or song.

Private by design

Most online editors upload your file to their servers. This one does not: decoding, EQ, rendering and export all run in your browser using the Web Audio API. Nothing is stored, and you can even keep editing if your connection drops after the page has loaded.

Tips for better results

  • Cut before you boost: removing a problem frequency usually sounds more natural than boosting others.
  • Use solo on a narrow band and sweep it to find harsh or boomy frequencies quickly.
  • Very large files (over about 400 MB) may not show a waveform or allow audio-only export; trim them shorter first.
  • For the smoothest video export, close other heavy tabs and keep the screen on.

Frequently asked questions

+Is the editor really free?

Yes. There is no sign-up, no watermark and no export limit. The site is paid for by the ads you see around the page.

+Are my files uploaded to a server?

No. Everything happens inside your browser on your own phone or computer. Your video and audio never leave your device, so the editor also works with private recordings.

+Which file formats can I open?

Anything your browser can play: usually MP4, MOV (on Safari), WebM, MP3, WAV, M4A/AAC, OGG and FLAC. If a file won't open, try converting it to MP4 or WAV first or use another browser.

+Can I extract the audio from a video?

Yes. Open the video, trim it if you want, then choose Export → Audio only. You get a WAV file with your EQ, volume and fades applied.

+Why does video export take as long as the clip?

Video is recorded while it plays through once in real time, so a 2-minute clip takes about 2 minutes. Audio-only export is rendered instantly.

+Do I get MP4 or WebM?

It depends on your browser. Recent Chrome, Edge and Safari versions export MP4; others export WebM. Both play in most players and upload fine to social networks.

+What is a dynamic EQ band?

A normal EQ band always boosts or cuts. A dynamic band only acts when that frequency gets louder than the threshold, for example taming harsh 's' sounds or a boomy bass note without dulling the whole track.

+Does it work on mobile?

Yes, the editor is designed for phones first. You can also add it to your home screen from the browser menu and use it like an app.
