【摘要】：本文提出了一種基于聲源分離理論的虛擬低音增強算法。文章分析了傳統(tǒng)虛擬低音增強算法的處理過程,發(fā)現(xiàn)對聲源中不同頻率成分的處理效果不統(tǒng)一,對最終的低音增強效果影響很大。所以結合聲源分離思想提出了一種新型的虛擬低音增強算法,在低音增強前對聲源進行瞬態(tài)穩(wěn)態(tài)成分分離處理,可以減小失真并提高低音增強效果。仿真實驗表明相比于傳統(tǒng)虛擬低音增強算法,本文所提算法所耗時間更短,并且低音效果和音質(zhì)也更好,對虛擬低音增強技術的推廣有重要意義。
[Abstract]:In this paper, a virtual bass enhancement algorithm based on sound source separation theory is proposed. In this paper, the processing process of traditional virtual bass enhancement algorithm is analyzed. It is found that the processing effect of different frequency components in the sound source is not uniform, and it has a great influence on the final bass enhancement effect. Therefore, a new virtual bass enhancement algorithm is proposed based on the idea of source separation. The transient steady state component separation of the sound source before the bass enhancement can reduce the distortion and improve the bass enhancement effect. Simulation results show that compared with the traditional virtual bass enhancement algorithm, the proposed algorithm takes less time, and the bass effect and sound quality are better, which is of great significance to the promotion of virtual bass enhancement technology.
