Patent attributes
In some examples, one or more processors configured by executable instructions may receive an audio signal and data to embed in the audio signal. For example, the data may be received dynamically from one or more data sources. The one or more processors may embed the received data in real time into the audio signal as embedded data based at least in part on controlling a phase angle of a selected frequency component of the audio signal. For instance, the embedded data may include at least one of text, a bar code, a quick response code, an image, a uniform resource locator (URL), or multimedia content. Additionally, the one or more processors may send the audio signal with the embedded data over a network to a plurality of electronic devices that include respective decoders for extracting the embedded data from the audio signal.
