Interleaved Audio

Abstract

DefinitionInterleaved audio transmission is a packet loss resilience technique based on sending alternate audio samples in different packets.Interleaved audio transmission is a technique that is sometimes used to alleviate network loss and act as a packet loss resilience mechanism [1,2]. The idea is to send alternate audio samples in different packets, as opposed to sending consecutive samples in the same packet. The difference between the two approaches is shown in Fig. 1.Interleaved Audio. Figure 1.(a) Transmission of consecutive samples, (b) Transmission of alternate samples.In Fig. 1(a) we see 24 consecutive samples being transmitted in one packet. If this packet is lost, there will be a gap in the audio equal to the duration of the samples. In Fig. 1(b) we see the interleaved approach for the same audio sample in 1a, where alternate samples are being sent in separate packets. This way if one of the packets is lost, we only lose every other sample and the receiver will he ...
