Surround sound is not only used in the fi lm, home theater, also penetrated the digital TV and digital broadcasting.But because of the limitation of storage media capacity and transmission bandwidth must use all kinds of that audio compression technologyto transmit audio data. As a more general and more practical signifi cance, as masking and by masking sound are not limited to their respectiveresend by a single speaker, but in different proportion to their respective ‘channel sound level is poor. To deal with this issue, this paperintegrates the signal denoising method as the optimization and achieves better performance.展开更多
