Constructor

Declaration

public MeanOpinionScore(double mos, double r)

Parameters

Type	Name	Description
double	mos
double	r

MeanOpinionScore(double, int, int)

This constructor calculates the MOS and R values given the packet loss percentage, the jitter and the network delay in milliseconds using the algorithm described in "EMOS - Estimated Mean Opinion" Score. See https://arimas.com/2017/09/12/emos-estimated-mean-opinion-score/.

Declaration

public MeanOpinionScore(double PacketLossPercent, int Jitter, int DelayInMs)

Parameters

Type	Name	Description
double	PacketLossPercent
int	Jitter
int	DelayInMs

Properties

MOS

mos estimate. The mos is in the range of 1.0 to 4.5. A value of 4.5 indicates the highest quality audio and a value of 1.0 is the lowest quality audio. A value of 0.0 indicates that the mos has not been calculated.

Declaration

public double MOS { get; set; }

Property Value

Type	Description
double

R

The R value is the rating value used to calculate the mos. It is calculated from the packet loss, the jitter and the delay.

Declaration

public double R { get; set; }

Property Value

Type	Description
double
