摘　　要：多通道广播音频信号在传输过程中,常常会受路径差异影响而出现相位偏移的问题,从而影响音质。多通道广播音频信号处理中,相位校正技术是提高音质和音频信号一致性的关键。基于此,研究多通道广播音频信号处理中的相位校正技术,旨在提高音频信号的整体质量。通过分析相位失真的成因及其对音质的影响,提出有效的相位校正方法。实验结果显示,相位校正技术能够明显减少相位失真,提高信噪比,降低谐波失真,从而增强音频信号的清晰度、立体感、空间感。In the transmission process of multi-channel broadcast audio signal,the phase deviation is often affected by the path difference,which affects the sound quality.In multi-channel broadcast audio signal processing,phase correction technology is the key to improve sound quality and audio signal consistency.Based on this,the phase correction technology in multi-channel broadcast audio signal processing is studied to improve the overall quality of audio signal.By analyzing the cause of phase distortion and its influence on sound quality,an effective phase correction method is proposed.The experimental results show that the phase correction technology can significantly reduce the phase distortion,improve the signal-to-noise ratio,reduce the harmonic distortion,and thus enhance the clarity,three-dimensional sense and spatial sense of the audio signal.
