Sound Wave Pro

An application that shows the sound wave of whatever is picked up by your device's microphone. You can also change the line thickness and color of the line, go full screen, or show a grid in the background. You can even set it as your live wallpaper!

---

Please note that this app does not save audio and your device must have a microphone in order to use.

Also, note that Google Assistant will not work while SoundWave Pro is active and live wallpaper support does not work for phones with MIUI installed.

Tap on the screen to open the action bar. From there you can enable "Single Trace Mode" or open the Settings screen.

To set as your LivewallPaper, long press on your home screen background and follow the prompts from there.
