About normalizing to 50% peak intensity, I still do not understand what does 50% mean. For sound pressure level, halving means -6dB.

So "0.99" does not mean 99 percent or so. there will be a peak that reaches -0.99 or +0.99, and no part of the sound will go outside the range (-0.99, +0.99). After doing that, the absolute peak will lie at 0.99 in the Sound window, i.e. I talked about normalizing the peak to 0.99 pascal. Phonetic Sciences, University of Amsterdam If you want both such uniform loudness and no clipping, use "scale intensity" and make sure the new average intensity is low enough. With "scale intensity", the perceived loudness of the resulting sound is more predictable than with "scale peak", though still not fully predictable. How can I decide which one is better than the other in certain situations?With "Scale peak", the resulting sound is guaranteed not to be clipped. "Scale intensity" will multiple the sound with such a number that the new average intensity is 70 dB, or any other value that you specify.

I am wondering what is the difference between the two, can I say that 'scale peak' will normalize the peak intensity, and 'scale intensity' will normalize the average intensity?no, "scale peak" scales the maximum absolute amplitude, as explained in detail with four pictures in the manual page about "scale peak".
There are two options for normalizing the intensity,'scale peak' and 'scale intensity'.
