Abstract: A method of audio source segregation includes selecting an audio attribute of an audio signal. The method also includes representing a portion of the audio attribute that is dominated by a single source as a source spiking event. In addition, the method includes representing a remaining portion of the audio signal as an audio signal spiking event. The method further includes determining whether the remaining portion coincides with the single source based on coincidence of the source spiking event and audio signal spiking event.

Abstract translation: 音频源隔离的方法包括选择音频信号的音频属性。 该方法还包括将由单个源主导的音频属性的一部分表示为源尖峰事件。 此外，该方法包括将音频信号的剩余部分表示为音频信号尖峰事件。 该方法还包括基于源尖峰事件和音频信号尖峰事件的一致性确定剩余部分是否与单个源重合。
