Dithering in Analog-to-digital Conversion
https://www.teledyne-e2v.com/content/uploads/2018/12/0869B_Dither_AN.pdf
To dither can be defined as adding some white noise to an analog signal destined to be digitalized. His-torically, this technique has been used mainly in the audio field in order to improve the sound of digital audio. Similarly, in the analog-to-digital conversion world, dithering can be used to enhance the dynamic range
HIGH RATE DATA HIDING IN SPEECH SIGNAL

claimed reaching a capacity of 1000 bits of data in a one-second segment of audio, using a frequency-selective phase alteration technique. In this paper, we propose a different approach to high capacity data hiding that can embed a large amount of encrypted message in unvoiced parts of speech signals conveyed by a typical voice file, e.g.

The dither signal can be at half sampling frequency and have an amplitude equal to half a quantising step together with white noise at a level of 4dB below the inherent quantising noise. In practice for point to point links, a single parity check digit is added to each 13 bit sample word.
