I’ve just tried Time Stretch for the first time in Wavelab 8 and find it reduces the level 0.4db, peak and rms. Is this as intended? Also, is it ok to use Wavelab 8 Time Stretch on 32 bit float files? I remember having some distortion issues when trying that in Wavelab 6, if the Peak Master was applied after.
Time stretching is a heavy treatment that can cause slight level changes. Nothing abnormal.
It is perfectly ok to use it on 32 bit float files, but keep in mind the above information.
