i, too, am having this problem and had hoped that this was fixed (my usual workflow has been to fix the pop in sound forge, but this proves tedious).
essentially, i am looking for “render as loop” functionality like ableton (and logic) has.
i put together a macro to get close to that functionality and all is well until exporting OUT of nuendo where a “pop” is introduced when listening in any editor such as sound forge/wavelab/audition, or even re-importing the stereo .wav into nuendo itself.
in nuendo, the pre-exported loop looks like this:
within nuendo at this pre-exported stage it loops seamlessly, but as soon as i choose either audio mixdown, render in place or export selected tracks the pop is introduced.
i am rendering out a file that is the same format/resolution as my session (in this case, 48k 32bit .wav). also, there are no plugins on my chain at this final export stage.
because there are two tracks that need to be blended together (to get the tail), “Bounce Selection” will not work.
