Speed Sound

声速意味着它根据您旅行的速度设置声音

This application does as the name says Speed Sound means setting the sound according to the speed.

Basically this application gets the speed you are moving at and sets the media volume according to the speed you are traveling at.

It displays the speed you are traveling at in KM/H. [others will be added soon]

for example :

------------------------

If your speed is more than 80km/h than volume will be the maximum volume of your device and the color of the car will be red

Likewise the color of the car and the volume will be changed according to the speed you are traveling at.

It will remind you of your speed without seeing into the speedometer .
