I wanted to render a stereo audio file, 48k/24bit/wav, which was recorded in ProTools.
(In ProTools, stereo files are dual-mono files and not interleaved.)
So, in WaveLab, I dragged the .L and .R files from the File Browser to the wave editor.
I trimmed the beginning of the file for about 200ms, and then I did ‘save as’ to save the trimmed file in new name.
Now, when I played back the new renamed file, the left and right channel weren’t in sync.
When I closed the file and re-opened it, it was playing normally.
It was reproducible with my other dual-mono files as well.
I wasn’t quite sure if you meant individual or stereo trims, but after trying it with stereo trim, you’re right. I get the same thing on Windows XP. If you open the dual mono’s as a stereo wav, trim the beginning and “save as”, it shifts the right channel to the right by the amount you’ve trimmed (in other words, it’s playing back the right channel without the trim). As you say, closing and reopening the file makes it as it should be.
