Abstract
The MIDI file is made up of hexadecimal digital control instructions, and it also has highly vulnerable. According to the characteristics of image watermarking technology and MIDI file, this paper improves the algorithm of embedding information in a single parameter by LSB method, and proposes a method of embedding digital watermarking in both time and strength parameters. This method can increase the embedding capacity and reduce the loss of sound quality and you can do blind extraction. At the same time, this paper analyzes the quality problem of MIDI audio embedded in watermark, and then puts forward some objective evaluation methods of MIDI audio.
