摘要翻译：
从单声道音频波形中充分分离多个源的“鸡尾酒会”问题仍未解决。目前对神经编码的生物学理解表明，相位信息在听觉通路的每个阶段都被保存和利用。然而，目前的计算方法主要是为了掩盖声音的振幅谱图而丢弃相位信息。在这篇文章中，我们试图通过一个神经似然的稀疏生成模型来解决在声音的频谱表示中保留相位信息是否能在人声和音乐轨道的单声道分离中提供更好的结果。我们的结果表明，保持相位信息可以减少分离轨道中的伪影，如信号与伪影比(GSAR)所量化的。此外，我们提出的方法在源分离方面达到了最先进的性能，平均信干比(GSIR)为19.46。

英文摘要：
  The "cocktail party" problem of fully separating multiple sources from a single channel audio waveform remains unsolved. Current biological understanding of neural encoding suggests that phase information is preserved and utilized at every stage of the auditory pathway. However, current computational approaches primarily discard phase information in order to mask amplitude spectrograms of sound. In this paper, we seek to address whether preserving phase information in spectral representations of sound provides better results in monaural separation of vocals from a musical track by using a neurally plausible sparse generative model. Our results demonstrate that preserving phase information reduces artifacts in the separated tracks, as quantified by the signal to artifact ratio (GSAR). Furthermore, our proposed method achieves state-of-the-art performance for source separation, as quantified by a mean signal to interference ratio (GSIR) of 19.46.
