Help! How do I turn my recordings into an mp3 file?

Hi can anyone help me. Ive recorded everything perfectly but I dont know how to turn the file into an mp3. Im used to a different program where theres a button that says turn into mp3 and have tried to figure it out but i find cubase very confusing. Can anyone help me??

Read the manual - “Export -audiomixdown”

You can’t export mp3 in the smaller versions of Cubase, but you can buy the mp3 upgrade patch from the Steinberg shop:
