AB  - With the advent of high-resolution recording and playback systems, a proportion of the ultrasonic frequency spectrum can potentially be utilized as a carrier for imperceptible data, which can be used to trigger events or to hold metadata in the form of, for example, an ISRC (International Standard Recording Code), a website address or audio track liner notes. The Sonic Quick Response Code (SQRC) algorithm was previously proposed as a method for encoding inaudible acoustic metadata within a 96 kHz audio file in the 30-35 kHz range. This paper demonstrates the effectiveness of the SQRC decode algorithm when acoustically transmitted over distance while evaluating the degradation effect of adding ultrasonic banded white noise to the pre and post transmission SQRC signal.
