I can slow down or make a track faster in realtime in Nuendo 5.x and that’s really cool tool for working the right tempo of a song already recorded.
So… can I take an already song audio files and pitch shift them so I could choose de best “tonal” for different singers?
I’m not 100% sure what you mean but you can adjust pitch in realtime too via various algorithms.
Yes you can - with Elastique Pro the quality of tempo shifted audio is quite acceptable for many applications. I still wouldn’t do it if ultimate audio quality is needed, though.
The methods are fully described in the manual, far too much to write down here.
Will try to download the last manual in PDF.
