“…(6)We focused on a situation of live performance, and watermarking has been achieved by amplitude modulation in frequency domain, with several composition methods in realtime. A real-time watermarking device that uses MCLT (Modulated Complex Lapped Transform) for embedding, with hardware implementation (8). This approach tries to reduce the time-delay with embedding procedure.…”

Digital instruments come to be used in Desk Top Music (DTM), live performance, etc. These performances are recorded as digital contents, and circulated actively through network and electronic media. Digital Water mark technology paid much attention to solve the problem of illegal distribution & duplication when the digital contents are spread over electronic media. In this paper, we focus on a sound synthesized process in digital instruments, and propose a audio watermarking based on wavetable switching method. Certain watermarks are embedded in wavetables that are included in our digital instruments, and the insertion of secret messages is actualized with wavetable switching. Additionally, embedded watermarks can be extracted from the acoustic signal. The proposed method is able to achieve a real-time watermark, i.e., both musical performance and the insertion of watermark can be actualized.

“…However, this method includes DFT (Discrete Fourier Transform) and IDFT (Inverse DFT) in the embedding procedure, and time-delay occurs during a large calculation between host signal and watermarked signal. Hernandez, et al [8] constructed a real-time watermarking equipment that uses MCLT (Modulated Complex Lapped Transform) for embedding, with hardware implementation. This approach tries to reduce the time-delay with embedding procedure.…”

Musical performance with digital instruments has become a common practice today, and many digital instruments came to be used in Desk Top Music (DTM), live performance, etc. These performances are recorded as digital contents, and circulated actively through network and electronic media. However, the spread of digital contents causes the problem of illegal duplication and distribution, so that digital watermark has recently attracted much attention as a technology to solve this problem. In this report, we focus on a sound synthesized process in digital instruments, and propose a real-time watermark method. Certain watermarks are embedded in wavetables that include in our digital instruments, and the insertion of secret messages is actualized with wavetable switching. Additionally, embedded watermarks can be extracted from the acoustic signal. The proposed method is able to achieve a real-time watermark, i.e., both musical performance and the insertion of watermark can be actualized.
