How to use it
- 1
Swipe left and right on the tool to switch between tabs, or tap a tab directly.
- 2
Channel Test — tap Left, Right, or Both and listen. One side silent? You found your problem.
- 3
Bass Test — pick a frequency and hit Play. Start at 60 Hz and work your way down to see where it drops off.
- 4
Sweep — hits 20 Hz all the way up to 20 kHz in one go. Listen for where things get thin or disappear.
- 5
3D Sound — put headphones on and start it. The sound should feel like it is moving around your head.
- 6
Sound Pan — the tone bounces left and right. Good for checking if both sides are equally loud.
- 7
Noise — tap White, Pink, or Brown. White is harsh and flat, pink sounds more balanced, brown is deep and rumbly.
About this tool
Everything here runs in your browser using the Web Audio API — no plugins, no installs. The channel test is the quickest way to figure out if a speaker has died or if one side is quieter than the other. The bass test lets you pick specific frequencies so you can hear exactly where your speakers start struggling. The sweep covers the whole audible range at once, which makes it easy to spot roll-off or weird resonances. The 3D mode uses HRTF filters that are designed to mimic how your ears naturally pick up sound from different directions — headphones give you the full effect. The noise generator is handy for shaking loose rattles or buzzing from a speaker grille, and pink noise in particular is what audio engineers use when setting up a room.
Six tests, one tool
Channel Test
Play a tone through just the left, just the right, or both at once. The fastest way to spot a dead or imbalanced speaker.
Bass Test
Pick from 20 Hz up to 120 Hz and hear whether your speakers can actually reproduce it. Most budget speakers start dropping off around 80 Hz.
Frequency Sweep
A slow scan from 20 Hz to 20 kHz. You will hear exactly where your speakers go quiet, thin out, or peak up.
3D Sound
Uses HRTF panning to make audio feel like it is circling around your head. Works best with headphones on.
Sound Pan
A tone that moves back and forth between left and right. Quick check for whether both channels are balanced and working.
Noise
White, pink, and brown noise. Good for testing full-range response and finding rattles. Pink noise is the go-to for speaker calibration.
