I’m on Wavelab Elements 12
PC 12th gen i9, 64GbRAM, Windows 11 Enterprise, 2Tb M.2 memory, RME Babyface Pro FS
I have an audio file in the edit widow and a set of effects in the Master Section. I click [Render] and I get the render options window.
I choose “Whole File”, “In Place” and “Bypass Master Section on Resulting Audio File”.
I click >Start.
Nothing. No change.
If I do the same but first select the entire audio file and, in the Render Options Window I choose “Selected Audio Range”, it works fine.
What am I missing, please?
Johnny
No problem here for this scenario.
Are you using 12.0.10?
If you don’t render in place, still no effect?
Thanks PG1 and congratulations! 
Yes, I’m using 12.0.10
Sorry about the late response … life!
It’s fine on named file and not names files, except that it spits out stereo files from mono source files and I can’t see how to stop that.
So it’s only for “In place” rendering and “Whole file”. I have to select the entire file and use “Selected audio range”. Not a killer but really REALLY irritating.
BTW, the current version is now 12.0.20 and not 12.0.10.
Do you mean, with the following settings? This works fine here.
Well done for having a system that works fine. That’s great. I’m very happy for you, I really am … mine doesn’t and I’m looking for help to fix my issue.
Anyone else got any ideas?
I would recommend resetting your preferences and try again:
Erase the folder: \AppData\Roaming\Steinberg\WaveLab Elements 12\
Aaaand there went all my presets and shortcuts! Thanks!
AND it made no difference to the process:
Record:
Then set up effects:
Then click on Render:
Choose the way I’d like to proceed:
Click on [Start] and view / listen to the waveform:
No change, except that the little red star in the bottom right is now flashing.
If I select the whole waveform and choose [In Place] and [Selected Audio Range] the effects are applied but this way - no.
I am no further forward, other than losing 20 or so presents and half an hour of my life re-creating the shortcuts.
Any ideas?
Oh and using this window:
Doesn’t work either.
I just did another test (with other plugins), and everything is OK. I have no clue why this does not work for you because it is a basic function, and this is the sole such report I have seen.
You could try with other plugins or even, remove all plugins and just change the Master Section’s fader level, to see.
Well this is clearly a bug, then.
It works fine with some plugins from Waves but no others.
How do I report bugs?
As PG1 is the main developer of WaveLab, you are quite good with reports here. Although it seems more like a plug-in related issue.
Have you tried to render each plug-in individually to see if the rendering is done correctly? You can either bypass every plug-in except one or even switch it off (right-mouse-click on the effect and deselect Active).
…
This option is just to bypass the Master Section automatically AFTER the rendering is done. It should in no way influence the plug-in chain for the rendering process.
This could be more of the issue.
What happens when you convert the file to stereo ?
The following option does not affect rendering (effects are applied); it merely instructs the Master Section to turn off processing after rendering is complete. This prevents the effects from being applied a second time when playing back the rendered file.
The following option is something else: it does bypass the Master Section plugins on rendering.
Laturec/PG: Correct I mixed things up. Would the renderering be affected in this case if the Bypass master section is active at the same time?
Edit: I deleted my original posting containing false information.
The two options are independent from one another.
So, then it is worth checking that the Bypass master section is not enabled too.
I know this is an old post but thought I would reply in case any one else is having issues. The problem here is that you are working on mono files but you are using stereo plugins.
In the first plugin slot, you need to insert “mono to dual mono” (this is found under Steinberg > Tools) before your waves plugins. If you want the rendered audio to be mono, when you render, in the “format” tab you need to select “mono -6b”. This should work.
