No problem with Nero Sound Tracks:
Click the multi-track project when you start Nero, and import the main audio
Then import the effect…drag it into the second parallel track to the position you want
You can copy and paste…move things around…add as many parallel effects as you want
Change the volume or pitch
When youÂ´re finished: export or “save as”
If you still canÂ´t get it come back and I or someone will explain in more detail. I just ran a quick test with some gothic metal and added a bird sound…took about 20 seconds to have something kinda interesting, but now I need to sleep.
