About Sound Signal
Sound Signal do digital signal transmission via sound.
Digital signal is usually described as 0 and 1. But how 0, 1 are transmitted?
Mobile phone does digital transmission via radio wave. Change frequency or amplitude to describe 0, 1.
Sound Signal use sound instead of radio wave.
This App recognize message you input as array of 0, 1 and transmit these digital signal by sound.
Emit fixed frequency sign wave sound for 1, and not emit for 0.
Actually digital signal is able to transmitted via any media. But radio wave or electric voltage is normally chosen because its speed and connection extent.
One of purpose of this app is transmit signal with human recognizable speed, so it's not fast.
And will be influenced background noise or echo of your environment.
But I hope you feel and enjoy digital signal transmission.
This app try to make visible the status of transmission.
Message view shows processed text message. You can use this like message app.
Sending status and receiving status view shows digital signal level which is sent or received.
Setting view has tools that to see signal wave form and FFT. And you can emit any sign wave from sign wave generator.
