First for starters, the way I’m using wavelab for mastering.
I import all the tracks and transform each one in a submontage, two times.
The first montage is digital preprocessing with external FX (analog loop) as last insert.
The second one “catches” the render of that first montage and get all the post processing + digital limiting as last insert.
The mother montage “catches” all the limited and finished masters, and in that montage I edit clips, markers, fades, etc.
Lately, I changed from wavelab 9.5 to 10, also computer and soundcard at the same time, so difficult to identifies from where comes my problem.
The problem is, that sometimes, in the rendered wav of a submontage, there is an audio drop, but a curious one. the files gets longer of one buffer and get padded at that point with (since I’m at 256 buffer size ATM) 256 samples at -oo dBFS. See first picture attached, I highlighted the zone and you can see in the bottom right that it’s exactly my buffer size :
So if I cut that part, you see that the audio lines up perfectly :
Is this a bug ?
Usually when there is a drop, you loose x number of buffers, but it doesn’t seem to do that here. What’s time consuming about that is that wavelab doesn’t inform anything about that, and it has been quite some time that I triple check every file that gets out.
Any ideas ?
