Abstract
In some examples, an audio signal is received and divided into a plurality of frames. Frequency domain data of the audio signal may be generated for an individual frame of the plurality of frames. For example, the frequency domain data may include a plurality of sinusoidal components. Data may be embedded into a selected sinusoidal component selected from the frequency domain data of the individual frame by controlling a phase angle of the selected sinusoidal component to represent a selected bit of the data. For instance, a first range of the phase angle may represent a first type of bit and a second range of the phase angle may represent a second type of bit.
