摘要
Abstract
An audio watermarking algorithm with self-synchronization based on complex cepstrum transform is proposed, which divides the original audio signal into several segments. Synchronization code is embedded into audio with the watermarks. The watermarks can be extracted without the original digital audio signal. The embedded watermarks are imperceptible and robust to many common attacks, such as noise adding, re-sampling, low pass filtering, re-quantization,cropping and so on.关键词
