Ultrasonic or data over audio transmission offers an incredible number of applications that range from facilitating peer to peer payments, to delivering timely mobile app promotions, to offering consumers a frictionless purchase experience. As a consumer, we’re often struck by the “tech”, but unclear on how exactly it works.
Web Audio API - Data transmission over sound - Slides
https://slides.com/robertrypula/data-transmission-over-sound
Speed of sound: 320 - 350 m/s (~ 1200 km/h) Radio wave is almost milion times faster! 50 Hz --> 6.7 m. 1 000 Hz --> 33.5 cm. 15 000 Hz --> 2.2 cm. Sound wave in air travels as local changes in pressure. Wave length examples: Speaker and mic needs to have moving part. Human hearing range: 20 Hz - 20 kHz.

The Optiva OTP-1DVI2A1UKM provides for the transmission of uncompressed DVI, VGA or Component (RGB / RGBHV / YPbPr) video, stereo analog audio, with USB KVM over long or short distances, using Dual-Link DVI-D and 10 Gbps Optics, up to …
Audio Network - data transmission over sound waves
https://audio-network.rypula.pl/
Internally AudioNetwork library uses Web Audio API for retrieving audio data from the microphone and sending audio data to the speakers. To be more precise it is using ScriptProcessorNode . ScriptProcessorNode fires event when new portion of samples arrives (from mic) or new portion of samples is required (for speakers).
