[Answered] Bit Depth Question

Files are controlled by the "File bit depths" settings in Preferences > File > Audio Data

Thank you.
This whole time I thought I was recording at 24.
DO you think I need to record all those parts, or is 16 sufficient for a professional sounding recording?

I do both music production and sound design. When producing music I go with 48kHz 24bit. The fact that the audio will end up as 44.1kHz 16bit or even mp3 later doesn't matter, because when the track is finished it won't be edited any more.
 
It's mainly because you get a more detailed sound to work with/edit (data-wise and sound-wise) with a higher resolution that you want to go with that.
 
When I do sound design I go even higher. I record all sound for my sound library at 24bit 96kHz (cuz that's how high my mobile recorder can go). These kinds of sounds are manipulated in all kinds of different ways later on, so here it's very important to have a high resolution of the source-file. Especially if you want to change the pitch of the sound later on it's important that the frequency resolution is high.
