In this paper we present concepts and corresponding implemenations to maximize the speed of audio atermarking encoders in order to be applicable in different scenarios. To motivate the development and implementation of fast audio watermarking encoders, application scenarios requiring high embedding speed are presented. Different concepts with assumptions concerning the underlying watermarking algorithms are discussed. The paper presents the necessary audio stream preparation and the corresponding implementation realizing the fast audio watermarking methods. The quality of the watermarked audio tracks and the robustness of the embedded watermarks will be verified by experimental tests. Enhancements of the fundamental principle concerning the distribution of audio tracks are discussed.
