Features

Built to disappear until someone talks to you

No integration, no playlist, no setup wizard: one switch on, and the music behaves like a person who noticed you are being spoken to.

♪ Speech, not noise

The detector follows the shape of a human voice instead of raw loudness, so steady room noise, traffic and fans stay out of the way.

≈ A fade that never clicks

The music drops through a smooth ramp over 100–1000 ms and comes back the same way. No hard cuts, no jump in the middle of a track.

▤ You can see the threshold

A live level meter marks the threshold in use, so you can watch the voice cross it and understand every decision the app makes.

● Voice profiles

Neutral (70–400 Hz), Deep (70–200 Hz) and Bright (140–450 Hz) shift the band analysis towards the voices around you.

☽ Works with the screen off

A foreground service keeps detection alive with the phone locked in your pocket, and its notification always offers the Stop button.

◁ Gives the mic back

During calls Eartrax steps aside and releases the microphone. The base volume is restored every time it is switched off.

How it works

Three steps, then never think about it again

  1. 1

    Play your music

    Start a track in any player. Eartrax works on the audio your phone outputs, so there is nothing to connect or pair.

  2. 2

    Tune it to your room

    Set the volume while speaking, pick a voice profile, or simply start from the Work, Home and Study presets.

  3. 3

    Talk

    The music steps back while you speak and returns 300–3000 ms after you stop, back at the exact level it was before.

The five controls, and nothing else

Every setting has a default that already works. You only touch it if your room asks for it.

FAQ

Questions people actually ask

The same answers that ship inside the app, under Help & FAQ.

What does Eartrax actually do?

Eartrax listens to the room through your phone’s microphone and detects when a human voice appears. While someone speaks, it lowers the music to the level you chose, then brings it back to exactly the volume you were at before.

Is my audio recorded or sent anywhere?

No. Audio is analysed in memory on the phone and discarded immediately. Nothing is written to storage or uploaded, and there is no telemetry, no analytics and no ads. Eartrax needs no internet connection to work.

Does it work with any music app?

Yes. Eartrax acts on the phone’s music volume stream, so it works with any player, podcast app or video app that plays audio on the device. There is no integration to configure.

Will a loud TV or an air conditioner trigger it?

Eartrax is tuned for the shape of a human voice rather than for loudness, so steady room noise is usually ignored. Other people’s voices coming from a TV or a speakerphone call can be detected, as with any voice detector. If it triggers too easily, raise the threshold or choose the Bright profile, which ignores low frequencies better.

Does it keep working with the screen off?

Yes. A foreground service keeps detection running with the screen locked and the phone in your pocket, with a permanent notification that shows the Stop button. During phone calls Eartrax deliberately stays inactive and releases the microphone.

Is Eartrax free?

The core is free forever: detection, automatic lowering, the level meter, the volume while speaking, ten sensitivity levels and the Neutral profile cost nothing. Premium is a single US$ 2.99 unlock (US$ 1.49 during the launch promotion) paid through Google Play, with no subscription, and it covers the personalisation settings. Every install also includes a 7-day Premium trial.

Which Android versions are supported?

Android 8.0 (Oreo, API 26) or later, on any phone with a microphone. A Google Play account is only needed for the optional Premium purchase, and per-app language selection on Android 13+ is supported.

The volume stopped lowering when I speak from further away. What now?

Start with the voice profile that matches the person speaking (Deep or Bright), then fine-tune the sensitivity. If the volume returns while you are still talking, increase the volume return time to around 1200–1500 ms.

How do I install it?
