Project settings - bit depth

Hi Guys,
i got a short questions. I was currently recording a few guitar tracks for reamping. Unfortunately, i have noticed i had set the project bit depth to 16bit instead of 24bit at one song. My question is, does cubase record/saves all files at 16bit (depending on the projects setting) or does this just effect the preview or export? Do i need to record the song again after setting the projects bit depth to 24bit or is it fine to change it afterwards?

Thanks in advance,

If you want your files in 24 bit, you need to record them with setup set to 24 Bit

You can change the project bit depth so any new recordings are 24bit no problem…but the existing files will be the same 16bit recordings you already made.
