A supraliminal channel is one in which the secret message is encoded in the semantic content of a cover object, and that is robust against an active warden. Such channels frequently have a very low embedding rate and therefore are unsuitable for more than simply exchanging steganographic public keys. This paper introduces a proof-of-concept supraliminal channel that uses WAV files to provide a high-bitrate method of embedding information in common media.
