WATERMARK LOADING DEVICE AND METHOD

摘要

A watermark loading device loads watermark to an original audio. The watermark loading device preprocesses the original audio to calculate a volume and a pitch of the original audio and saves the volume and the pitch as audio information of the original audio. The watermark loading device configures relevant parameters of watermark loading including a watermark loading intensity, a volume threshold and a pitch threshold used for choosing a target fragment of the original audio that is to be loaded watermark. The watermark loading device compares the audio information with the volume threshold and the pitch threshold to determine the target fragment and loads watermark for the target fragment according to the watermark loading intensity to get a watermarked audio.
