Can you transmit data through sound?

The process of using sound waves to transmit digital data; sound waves are locally encoded and broadcasted from a device and locally decoded via another device or series of devices using speakers and microphones.

How does sound transmit information between digital devices?

Transmission of sound waves in telephony

The sound waves are converted into electrical signals by a microphone and transmitted in analog or digital form via the telephone network. For digital transmission, the analog signal has to be transformed into a digital signal by means of sampling, quantisation and coding.

How does sound travel through a computer?

For the computer to make a sound, the stored digital waveform is clocked out through a digital to analog converter (part of the soundcard chip, which has one for each channel), then passed through an analog amplifier to a loudspeaker.

How does data over sound work?

Data over Sound is a wireless communication technology to exchange digital data between devices. Data over Sound uses near ultrasonic sound waves or sometime audible sound waves to encode data and does not need any specialized hardware and antennas like WiFi, Bluetooth, or NFC.
