Precision Audio Tool

Personalize Your Listening Experience

Measure your headphones' frequency response and generate a custom compensatory Equalizer preset.

Equal-Loudness Match

Compare tones at different frequencies against a 1000 Hz reference. Equalize the subjective volume to build a precise response curve.

Aero Compensator

Our algorithm boosts deficient bands and controls peaks, optimizing soundstage and detail without causing digital distortion.

Hearing Safety Warning: This test plays pure test tones. Keep your starting system volume low (around 10%–20%) to prevent sudden hearing strain or damage.
Step 1 of 2

Baseline Calibration

Set your reference volume level using a standard 1000 Hz mid-frequency tone.

Reference Tone
1,000 Hz

Human hearing is highly sensitive here. This will serve as your loudness benchmark.

Instructions

  1. Click the Play button above to hear the 1000 Hz calibration tone.
  2. Adjust your system (physical) volume so that the tone sounds like a comfortable, quiet hum (not loud, but clearly audible).
  3. Once you have a comfortable reference baseline, click "Lock Baseline & Continue".
Step 2 of 2 — Frequency 1/5

Testing Sub-Bass: 60 Hz

Match the volume of the test tone until it sounds exactly as loud as the 1000 Hz reference.

A: Reference
1,000 Hz
B: Test Tone
60 Hz
Quieter Match Loudness of Tone B to Tone A Louder
Relative Level: 0 dB
