Measure It, Then Hear the Fix

Pop Filter & Sibilance Analyzer

Measures how harsh your "s" and "t" sounds are relative to the rest of your voice, then lets you hear a live simulated pop-filter effect through a real-time EQ cut — so you can decide whether buying one is actually worth it before you do, rather than guessing from a single number.

Test Phrase

"Steve saw six silver snakes slither swiftly past the store."

Read this aloud a few times at your normal speaking distance once the mic is live.

How to Interpret Your Results

What your sibilance ratio actually means

The ratio compares energy in the 5–9kHz sibilant range against your overall 200–4000Hz voice band while you read the test phrase — a direct spectral measurement, not an estimate. A high number means "s" and "t" sounds carry disproportionate energy relative to the rest of your speech.

Under 0.35Balanced. Sibilant frequencies are proportioned normally — a pop filter would not meaningfully change your sound.
0.35–0.55Slightly bright. A mild edge on "s" and "t" sounds, worth a free fix like mic angle before spending on hardware.
Over 0.55Harsh. Sibilants are disproportionately loud — use the live Preview toggle to hear roughly how much a pop filter would help before buying one.

Balanced< 0.35None needed — skip the pop filter purchase.

Harsh> 0.55Preview the fix live, then consider a pop filter.

These bands are this tool's own measured thresholds, from real 5–9kHz vs. 200–4000Hz spectral energy.

Step-by-Step

How to Run the Test

  1. Click "Start" and allow microphone access when prompted.
  2. Read the test phrase aloud at your normal speaking distance and volume.
  3. Read your sibilance ratio and verdict once it stabilizes.
  4. Click "Preview" to hear a simulated pop-filter effect live — headphones recommended to avoid feedback.

Notes

What the ratio measures

Sibilant sounds concentrate energy in the 5–9kHz range. This compares that energy against your overall 200–4000Hz voice band — a high ratio means "s" and "t" sounds are disproportionately loud relative to the rest of your speech, which is exactly the harshness a pop filter or mic-angle adjustment addresses.

Common Issues

Troubleshooting & Fixes

Angle your mic off-axisPointing the capsule slightly away from a direct line to your mouth reduces plosive and sibilant impact for free, on any mic.
Increase distance slightlyA little more space between mouth and mic softens both sibilance and proximity-effect bass boost.
Software EQIf your recording or call software has an EQ option, a gentle high-shelf cut around 6–8kHz approximates what a physical pop filter does.
Preview mode sounds distorted or feeds backLower your speaker volume or switch to headphones — Preview plays your live mic back through your speakers in real time.
Microphone access blockedClick the camera/mic icon in your browser's address bar to confirm this site is allowed, or check your OS's microphone privacy settings.

Common Questions

Frequently Asked Questions

Do I actually need a pop filter?
If your sibilance ratio reads harsh, a pop filter or an off-axis mic angle will likely help — use the live Preview toggle to hear roughly how much difference it would make before buying anything.
Is the preview an exact simulation of a real pop filter?
It is a reasonable approximation — a real-time high-shelf EQ cut above 6kHz — rather than an exact acoustic model of a physical filter. It is close enough to give you a genuine sense of the improvement, not a promise of the identical result a specific product would give.
What's the difference between this and the sibilance reading in the microphone test?
The microphone test reports sibilance as one line among several acoustic metrics. This tool is built entirely around the pop-filter decision specifically, including a live before/after preview so you can hear the fix rather than just see a number.
Why does preview mode warn about headphones?
Preview plays your live microphone back through your speakers in real time, which can create audio coupling or a delayed echo if your speakers and mic are close together — headphones avoid that entirely.
Will a pop filter fix plosives too, or just sibilance?
Physical pop filters primarily address plosive bursts from "p" and "b" sounds — sibilance reduction is more of a side effect. This tool measures sibilance specifically; a separate low-frequency check would be needed to grade plosive performance.
