Description: Base on DWT of the digital audio watermarking algorithm，the audio signalhas been transformed by DWT, the energy of detail coefficient of the first three sections has been compared. According to energy comparison and watermark bit. Adopting the way of not changing or reducing energy of the detail coefficient, the watermark has been embedded into the detail coefficient.
