Abstract
An encoding method for embedding a watermark into an audio is provided. A text watermark and an original audio are obtained. The text watermark is converted to an image watermark. The original audio is converted from a time domain to a frequency domain to generate a pre-process audio. The image watermark is embedded into the pre-processed audio to generate an encoded audio. The encoded audio is converted from the frequency domain to the time domain to generate an watermarked audio.
