摘要:

提高历史音乐录音的音质是一个长期存在的问题。本文提出了一种基于全卷积深度神经网络的新型去噪方法。设计了一个两阶段的U-Net模型架构,以高保真度建模和抑制退化。该方法处理音频的时间-频率表示,并使用真实的噪声数据进行训练,以联合去除旧模拟光盘中的嘶嘶声、咔嗒声、重击声和其他常见的附加干扰。该模型在客观和主观指标上都优于以前的方法。一个正式的盲听测试的结果表明,真正的录音去噪与这种方法有显着更好的质量比基线方法。这项研究显示了真实训练数据的重要性和深度学习在音频恢复中的作用。

英文摘要:

Enhancing the sound quality of historical music recordings is a long-standing problem. This paper presents a novel denoising method based on a fully-convolutional deep neural network. A two-stage U-Net model architecture is designed to model and suppress the degradations with high fidelity. The method processes the time-frequency representation of audio, and is trained using realistic noisy data to jointly remove hiss, clicks, thumps, and other common additive disturbances from old analog discs. The proposed model outperforms previous methods in both objective and subjective metrics. The results of a formal blind listening test show that real gramophone recordings denoised with this method have significantly better quality than the baseline methods. This study shows the importance of realistic training data and the power of deep learning in audio restoration.
