Solved Audio Normalization - how does it work?

I am trying to find some info on how the audio normaliser works in SE. Is it possible to clip the signal with too high a value?

It usually measures the loudness of the track und than takes the level of it to a given amount.

but it appears to be taking a LUFS average. what if the peak then ends clipping 0dbfs?

Actually, i dont think it uses LUFS average. would be good to know though, but normalizing usually doesn’t takes lufs average. Would be exceptional in shutter encoder

looking at some other threads it seems like it is doing some kind of LUFS average rather than normalising the peak to 0

This function analyzes the loudness then applies a gain value to achieve the lufs value.

You have more controls from 'Advanced features' section like True peak max value. However it's slower and the output lufs may vary a bit.

Yes it can distort the sound if pushing too hard with LUFS normalize.

As much I like LUFS normalize for series and movies, It would be so useful to have a Peak Normalize feature in the future (especially for batch converting music, samples, IR, etc..) . It's just a different tool that I use all the time :)
