摘要
数字音频水印在音频转码或经音频在空气中播放转录后不能保留,具有很大的局限性.基于此,提出一种音频的模拟水印加注方法,并分析了详细的设计流程.该方法在设计时针对人耳听觉特性进行了优化,不会影响音频的整体听感,适用于转码、压缩及空气传播等典型音频传播场景.
Abstract
Digital audio watermarks cannot be retained after audio transcoding or transcription in the air, which has significant limitations. Based on this, a method for adding analog watermarks to audio is proposed, and a detailed design process is analyzed. This method optimizes the auditory characteristics of the human ear during design, without affecting the overall auditory sensation of the audio. It is suitable for typical audio propagation scenarios such as transcoding, compression, and air propagation.
