Is it real time audio rendering?

Hi, I just discovered this software and I have a ton of projects I'd like to create!

I want to know if the audio is always rendered in real-time or there's an option to change it. (I tried using the midi playback and an audio import as well, but the audio is always rendered in real-time. The video is rendered really fast, BTW.

I want to buy it, but I would like to know if I would be able to render audio faster! Thank you so much!
