Today large amounts of multimedia data are available which can be easily distributed, e.g. by the Internet. To track illicit copies or to prove ownership of digital data, watermarking is a well-known technique. Regarding the audio quality, however, concerns about potential degradations are voiced frequently. This paper investigates the audio quality of a presented watermarking scheme including results of objective and subjective measurements. These results are viewed in relation to those of perceptual coding schemes. Along with these data, the corresponding performance of the watermarking detection is given.
