A very basic application that shows the sound wave of whatever it hears. You can see what sound looks like from what is picked up by your microphone. Behaves like a sound oscilloscope.

Check out Sound Wave Pro (https://play.google.com/store/apps/details?id=com.synaptik.soundwave.pro), it has more features than Sound Wave and includes Live Wallpaper support!

This app does not record any audio.
