| Member | Type | Description |
|---|---|---|
| burstLossLength1 | float | Ratio of lost single lost packet over the total number of packets for the session. |
| burstLossLength2 | float | Ratio of two consecutive lost packets over the total number of packets for the session. |
| burstLossLength3 | float | Ratio of three consecutive lost packets over the total number of packets for the session. |
| burstLossLength4 | float | Ratio of four consecutive lost packets over the total number of packets for the session. |
| burstLossLength5 | float | Ratio of five consecutive lost packets over the total number of packets for the session. |
| burstLossLength6 | float | Ratio of six consecutive lost packets over the total number of packets for the session. |
| burstLossLength7 | float | Ratio of seven consecutive lost packets over the total number of packets for the session. |
| burstLossLength8OrHigher | float | Ratio of eight or more consecutive lost packets over the total number of packets for the session. |
| fecRecvDistance1 | long | Percentage of session where packets with FEC distance of 1 were received. |
| fecRecvDistance2 | long | Percentage of session where packets with FEC distance of 2 were received. |
| fecRecvDistance3 | long | Percentage of session where packets with FEC distance of 3 were received. |
| packetReorderDepthAvg | long | Average of the number of packets between when the current packet and the out-of-sequence packet was received. |
| packetReorderDepthMax | long | Maximum of the number of packets between when the current packet and the out-of-sequence packet was received. |
| packetReorderRatio | float | Ratio of packets received that were out of sequence during the session. |
| ratioCompressedSamplesAvg | float | Ratio of the number of audio frames with samples that have been compressed to compensate for jitter or loss to the total number of audio frames. Described in [MS-QoE] Section 2.2.1.12.1. |
| ratioConcealedSamplesAvg | float | Ratio of the number of audio frames with samples generated by packet loss concealment to the total number of audio frames. Described in [MS-QoE] Section 2.2.1.12.1. |
| ratioStretchedSamplesAvg | float | Ratio of the number of audio frames with samples that have been stretched to compensate for jitter or loss to the total number of audio frames. Described in [MS-QoE] Section 2.2.1.12.1. |
| samplingRate | unsigned long | Samples per second. |
| signal | MSAudioRecvSignal, | Metrics regarding signal level and noise. |
