A system that can function without communication networks – that is increasingly turning out to be a necessity for organizations cutting across sectors. Recognizing this need, ITC Infotech has partnered with Chirp to leverage their expertise in data-over-sound technology. Data-over-sound technology works by encoding sounds of various pitches and tones on the broadcasting device and decoding them on the receiving device.

Data-over-sound technology can run on virtually any device or machine, ranging from smartphones to legacy industrial equipment, all that is needed is a microphone or a speaker. It negates the need for Wi-Fi, Bluetooth, cellular network and other popular connecting technologies.



The audio data encoding is perfectly suited for broadcasting data to a whole range of devices. The solution allows devices to work well with the ones that they have never been paired with before.

Along with that, it allows audio data access and transfer without the need for network connection. Encoding heavy data into sound makes accessibility and portability easier, allowing customers to share data through different platforms. The new audio encoding technology does not directly implement any security setting on the data, but is flexible enough to allow the user to implement partner security measure before sharing.

Here are a few features:

  • Accessible on various platforms: iOS, Mac OS, Android, Windows UWP, JavaScript, Web Browsers, Android TV, Python, Arduino, Raspberry Pi and Linux
  • Bandwidth for sending/receiving: 50-100 bits per second
  • Range of transmitting: Over 10 to 15 feet, but can be extended to a couple of 100 feet
  • Frequencies used: Standard SDKs use frequencies between around 2 kHz and 12 kHz Ultrasonic SDKs operate in the region of 19 kHz
