What are the valid output range of feature values? about opensmile HOT 2 CLOSED

from opensmile.

Thanks @chausner-audeering , problem is resolved now. So I was just observing the features of single audio file without normalization. The output was as follows,

But then i collected feature vector of multiple audio files in one and then performed normalization across all those file then i got plot of those 6373 features like as follows.

So all other features are normalized with respect to other file's features. So we have to see a particular feature across multiple files.

I actually came to this confusion/problme while designing the following pipeline

audiofile.wav -> audio processing -> opensmile Feature extraction ->Normalization

So got confused in the Normalization part that how do i normalize single audio feature?

but now i am following following pipeline

multiple audio files -> audio processing -> opensmile Feature extraction -> feature vectors of multiple audio files -> normalize

Thanks again @chausner-audeering ,
I am closing this issue
