Precise times
Rumble, traffic, handling noise, desk thumps — unwanted low end is baked into most real-world recordings. A high-pass filter keeps everything above your cutoff and rolls off everything below: the honest fix that never guesses. Drop a file, sweep the cutoff up until the rumble disappears and the voice stays full, export. Everything runs in your browser: the file is never uploaded.
When to high-pass audio
- Clean traffic rumble and desk thumps out of podcast and voice recordings.
- Remove wind and handling noise that survived a windy outdoor take.
- Tighten a mix by clearing sub-bass mud out of every non-bass track.
How to use the High Pass Filter
-
Drop your audio
Any MP3, WAV, M4A, OGG or FLAC file. Processing stays on your device.
-
Raise the cutoff
Sweep up from 20 Hz until the rumble is gone — 80–120 Hz suits most voices.
-
Preview and export
Check the voice does not sound thin, then export as MP3 or lossless WAV.
Everything below the cutoff goes
A high-pass filter rolls off what is below the cutoff: rumble, wind, handling thumps, and the low end of a boomy room. It does not change pitch, and it does not resample.
Mains hum sits at 50 or 60 Hz, with harmonics above that. A high pass around 80–120 Hz removes the fundamental and much of the ring. Stubborn harmonics are still there. Pair it with the low-pass filter if you need to narrow the band further.
How high before a voice thins out
Speech has body in the low mids. Push the cutoff too far and the voice turns thin:
- Male voices keep their body down to about 100 Hz.
- Female voices down to about 150–200 Hz.
- Past 300 Hz, speech starts to sound like a telephone. That can be a style, so listen before you export.
Not the bass booster, and not a cut shelf
The bass booster adds level below 150 Hz. This page removes level below a cutoff you sweep. They solve opposite problems.
The equalizer can cut a few decibels at 150 Hz and leave the rest of the low end. Use that when the file is a bit muddy and you still want the weight. Use this page when the rumble should be gone.
High Pass Filter FAQ
Is my audio uploaded?
No. The filter is a Web Audio high-pass biquad inside your browser tab — there is no upload step. You can go offline after the page loads and the tool keeps working.
Will it remove hum from a bad cable?
Mains hum sits at 50 or 60 Hz, with harmonics above. A high pass at 80–120 Hz removes the fundamental and much of the ring — for stubborn harmonics, pair it with the low-pass filter to narrow the band further.
How high can the cutoff go before voices thin out?
Male voices keep their body down to about 100 Hz, female voices to about 150–200 Hz. Push past 300 Hz and speech starts sounding telephone-like — that can be a style, but listen first.
How is this different from the low-pass filter?
Opposite directions: the high pass removes low-frequency rumble below your cutoff; the low pass removes hiss and harshness above it. Chain them and only your chosen band survives.
Does filtering reduce the file quality?
No resampling or pitch change happens — the cutoff only decides which frequencies survive. Export re-encodes once, as always: MP3 at 128–320 kbps or bit-perfect WAV.
Does it work on a phone?
Yes. The editor is built for touch — drag to select, sweep the cutoff, export. Works in current Chrome, Edge, Firefox and Safari, on desktop and mobile.
