Audio Trim


I have 12+ audio tracks that I have had to shift ‘back in time’ to correct timing with the other tracks.

I now need to send these tracks to the engineer so they can be mixed, (as 30+ individual audio files), but the original audio files these shifted files Cubase is referencing don’t have the time shift applied.

My question is how do I apply the time shift to the original files, the shift was in milliseconds and made via the individual audio parts info line box. I don’t wont to do it as an audio (re)export. Is there a way to apply the timing correction without re-exporting?
