Acoustics Scanner

A short scan of the room you are about to sing in: five seconds of quiet, then two claps. It measures reverb and background noise, then tells you in plain words whether it is fit to record or measure in.

What the scan measures

Two numbers, one verdict, no acoustics degree required.

How long the room rings
drygoodboomy

Decay time. A dry room flatters nothing but measures honestly; a boomy one makes everything sound better and every reading worse.

Good looks like: 0.3 to 0.6 seconds. Past a second, move rooms or add soft furnishings.

The background floor, in dBFS: decibels below the loudest sound your mic can take, so a lower number is quieter. It is split low, mid and high. Traffic sits low, fans sit mid, hiss sits high, which tells you what to switch off.

Good looks like: below −50 dBFS, which the app calls quiet. Above −40 dBFS the room reads as loud.

Whether to sing here

One word, then the detail if you want it: good, usable or poor, with the single change most likely to improve it.

Good looks like: "Good" before any VSI scan you intend to trust.
Three steps
How it works

Stay quiet for five seconds, then clap twice. That is the whole method.

01Step 01
Stand where you will sing

Position matters as much as the room. Scan from the spot you actually use.

02Step 02
Five seconds of quiet, then two claps

The quiet part measures background noise. Each clap shows how long the room rings. Audio never leaves the device.

03Step 03
You get a verdict and a fix

Not just numbers: the one change — close the window, add a rug, move off the wall — most likely to help.

Measure the room, then your voice
