FOR THE SOUNDS THAT KEEP COMING BACK

“It was loud” is
only half the story.

Traffic outside the window. Renovation next door. An appliance that won’t stop humming. Hush brings the reading and the context into one record, ready to revisit or share.

See how it changes.

  • Live levels and historyWatch the sound evolve, then revisit the recorded timeline.
  • Choose how you measureA, C and Z weighting, time-response controls, and an advanced ITU-R 468 mode.
  • Look closer at the soundAverage, maximum, peak and background statistics, with frequency analysis for more detail.

Phone readings are indicative. Device, input and reference settings matter.

02 / CAPTURE

The sound.
And everything
around it.

Open Live camera to put sound levels, location, date and time alongside the scene. Add photos or video during a recording so the context stays with it.

  • Photos and video attached to the recording
  • Choose whether video includes sound
  • Save into a new or existing dossier

A FEW THINGS TO KNOW

Before you
press record.

Is Hush a certified sound level meter?

No. Hush provides indicative readings from your phone’s microphone. Results depend on the device, input, surroundings and reference settings. Use a suitable calibrated instrument where a certified or defensible measurement is required. Hush does not establish hearing safety or legal compliance.

Does measuring save an audio recording?

The meter preview is temporary. Starting a recording keeps the levels and measurement history. Retaining sound-only audio is a separate setting, and you choose whether camera video includes sound.

What exactly is a dossier?

A named collection of related recordings. Each recording keeps its own date, saved location, details and attached media. You can add new recordings or move existing unfiled recordings into it.

Can I download Hush now?

Hush is currently in TestFlight and coming soon to the App Store. Purchases are disabled in the current test build. Questions? Get in touch with us.
