K-factor - MLQKvr

[riteshchandra2]

Does anybody know what this metric really is : MLQKvr ?

I have CMR with varVQMetric showing different K-Factor values but I am not sure what Kvr is for ? 

MLQK=4.5000;MLQKav=4.4936;MLQKmn=4.4438;MLQKmx=4.5000;MLQKvr=0.95;CCR=0.0001;ICR=0.0000;ICRmx=0.0033;CS=2;SCS=0

Can someone advise here please?

Thanks in advance,

Chandra

Hi Ritesh,

It is the MOS LQK version field.

MOS LQK

MOS Listening Quality K-factor provides an estimate of the MOS score of the last 8 seconds of speech on the reception signal path.

The specific field "MLQKvr" is not defined in that document, nor any other I've found.

I've also noticed that it always seems to display a value of 0.95 both in my own reports and the samples I've seen while researching.

Anyone have any extra info on this? As the value never seems to change, I'm not sure how useful it could possibly be.
