The core of acoustic data transmission can be identified as OFDM (orthogonal frequency division multiplexing), which, along with the adaptation of subcarriers to the original music over time, allows for the maximum utilization of the transmitted frequency spectrum for information transfer. Thanks to this, it has been possible to achieve a transmission speed of 412 bits\/s over a distance of up to 24 meters (error rate < 10%). Practical experiments involving 40 volunteers confirmed that it is practically impossible to hear the difference between the original melody and the one into which the information was embedded.<\/p>\n

Where can such technology be applied in practice? Researchers have their own answer: almost all modern smartphones, laptops, and other portable devices are equipped with microphones, and many public places (caf\u00e9s, restaurants, shopping centers, etc.) have speakers playing background music. Data, for instance, for connecting to a Wi-Fi network can be embedded into this background melody without the need for additional actions.<\/p>\n

The general features of acoustic data transmission are now clear; let's move on to a detailed study of the structure of this system.<\/p>\n

System Description<\/h3>\n

\nEmbedding data into the melody occurs through frequency masking. In time intervals, masking frequencies are identified, and OFDM subcarriers close to these masking elements are filled with data.<\/p>\n
