As discussed here https://www.gearslutz.com/board/steinberg-cubase-nuendo/1224019-cubase-audio-export-inserts-silence-beginning-file.html?posted=1#post13428976, Cubase 9.5 inserts silence at the start of an exported mp3-file.
How to reproduce:
- Generate an Audio Click with the default click sound
- Export as mp3
- Open file in an other editor than Cubase (for example Audacity)
See attached screen capture. On top is an mp3, below is a wav exported from the exact same project.
