First thing I need to know more about the definition 'normalize' audio.
So, (with an audio example from Audacity) does this mean
1.expand the amplitude to 0db (or -1db like audacity does when normalizing)
2.or do I need to bring the center of the amplitude up?
I meant like the -36db 'as center' on the following image
You should have used words in more straightforward manner.
So, statement is probably wrong?: do I need to bring the center of the amplitude up?
First of all I do not see a statement, I see a qustion. And the question for me is simply meaningless, in particular "center of the amplitude". Amplitude is a quantity, it has no "center". The Audacity mark might be at center, but it is not a "center of amplitude".
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
To improve my recognition accuracy I'm looking into normalizing my audio.

You can learn many things from Wikipedia
https://en.wikipedia.org/wiki/Audio_normalization
Yes
I have no idea what do you mean by a "center of the amplitude"
Nickolay,
Thanks for the info.
I've been reading a lot about audio and normalization, including wiki's.
I just want to be sure I have interpreted it properly.

Sorry for mixing up/missing words.
I already had my answer how to approach normalization, thanks for that.
PS: i meant the statemeant 'I need to bring the center of the amplitude up' , but surely the reference wasn't clear anough.
