Abstract
Techniques for concurrent transmission of audio and ultrasound are described. In an example, a computing device generates, in a digital domain, mixed audio data from multiple sets of audio data, each set corresponding to a different audio channel. The computing device also generates, in the digital domain, ultrasound data, and generates serial data by providing the mixed audio data and the ultrasound data as different inputs to an I2S mixing module. In an analog domain, the computing device generates an output signal based at least in part on the serial data, and sends the output signal to a speaker.
