Save on project memory tips

I’m wondering if you can give me any tips regarding saving on storage space in my project.

I like to chop a vocal or copy and paste it a lot however I know the project will store the full length of the audio even if I’m not using the full length… once I choose the clip from the audio how do I make remove the audio that sits behind it… hope that makes sense


“Bounce selection” then remove or delete the original file


So you just highlight all the audio in the channel and go to audio menu and bounce? Thanks
