Speed of Sound

Adjust volume according to speed
N.B The app no longer requires Google Maps to install but the app will
crash if you try to access the maps without having it.

N.B It isn’t possible to view your position on a map because Google Maps
is the only map source and the API keys are not in the source code. If you need
to use Google Maps install the developer’s build from the website.

Keep your eyes on the road, not your phone! Speed of Sound automatically adjusts
your music player’s volume while you’re driving about with your GPS, lowering
the volume while driving slowly or at a stoplight, and cranking it up on the
highway.

This is a feature available in some more expensive cars and sound systems. We’re
giving it to you for free to use on your phone. Just start up your music player,
plug your phone into your car stereo, and open Speed of Sound.

Packages

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.

Download F-Droid
  • Version 0.8.2 (9) suggested Added on 2013-01-19

    This version requires Android 2.1 or newer.

    It is built and signed by F-Droid, and guaranteed to correspond to this source tarball.

    Permissions
    • access precise location only in the foreground
      This app can get your precise location from location services while the app is in use. Location services for your device must be turned on for the app to get location. This may increase battery usage.
    • run at startup
      Allows the app to have itself started as soon as the system has finished booting. This can make it take longer to start the phone and allow the app to slow down the overall phone by always running.
    • have full network access
      Allows the app to create network sockets and use custom network protocols. The browser and other applications provide means to send data to the internet, so this permission is not required to send data to the internet.
    • pair with Bluetooth devices
      Allows the app to view the configuration of the Bluetooth on the phone, and to make and accept connections with paired devices.
