In WL 11 it redraws the waveform in real time, In WL 12 it takes a while to redraw the waveform

Why is that? Just wondering???

Can you be more accurate in your description?

If you use the new Rainbow view, then yes it takes more time, because of the additional needed audio analysis.

In the standard mode, it is a bit slower than in the past, because of the new overlay RMS feature. But the difference is not that much.

In all cases, WaveLab is very fast in this domain. Of course, you also need a fast computer to achieve the best results (CPU + NMVe disk).

If I process a wave with a plugin the file in WL11 the waveform just changes from what it was to the new waveform. It is drawn in a microsecond. If I do the same thing in WL 12 it goes blank then redraws the waveform from left to right. It is not a problem but I was wondering why the difference? Lots of things on WL12 are “different”. Thanks for the reply. I am talking about just a standard waveform, nothing fancy like the rainbow. I guess I just got use to the “old way”.

FWIW My computer is basically a gaming computer on steroids.

I have investigated this issue, and you are right. There is an option called “Create Peak Files When Writing Audio Files,” which is ON by default. But it does not work when WaveLab creates temporary files. The consequence is what you observe: the peak file is rebuilt at the end, rather than progressively when writing the audio file.
The good news is that this will be fixed for WaveLab 12.0.50.
