FFAStrans forum

Hi Steinar,
I don't know if it is intentional or not (bug or feature), but when I use the loudness analyzer, it always gives me as many values as I have seperate audio streams in my input video. R128 specifies however, that all channels should be summed together for one single value for programme loudness. Could you take a look at that?
Thanks!

Hi novalis,

That's correct and it's a feature, not a bug. FFAStrans will allways give you a separate value for all channels, no matter how you have configured the node. So you will notice that if you f.ex. evaluate stereo pairs in a four channel file, your array will look like this: [value1, value1, value2, value2]. "value1" is the combined measure of the first two channels and "value2" is the combined measure of the 3'rd and 4'th channel.

Hi steinar,
not shure, if I understand correctly: When I evaluate a stereo pair in a stereo file, I get [value1, value1] - correct?

That's correct. If you would evaluate a stereo file as two mono channels you would get [value1, value2].

great, thanks a lot!
