Abstract: A method for packet loss concealment, that includes: continuously receiving a digital audio stream; extracting audio features from the digital audio stream while the digital audio stream is unharmed; and upon detecting a gap in the digital audio stream, filling the gap with one or more previous segments of the digital audio stream, wherein the filling is based on a matching of the one or more of the extracted audio features with one or more audio features adjacent to the gap.

Abstract translation: 一种用于分组丢失隐藏的方法，包括：连续接收数字音频流; 在数字音频流不受干扰的情况下从数字音频流中提取音频特征; 并且在检测到所述数字音频流中的间隙时，用所述数字音频流的一个或多个先前段填充所述间隙，其中所述填充基于所提取的一个或多个所述音频特征与一个或多个音频特征 毗邻差距。
