I make cool stuff with blender, where it is more realistic and can do way cooler things, but, it takes a long time to render. Is there any daw that can render strange hyper-realistic sounds instead of faking everything in realtime? Or is the faking everything in real time good enough?
Audio processing requires less processing than video, allowing digital audio to be rendered in real time (well, nano seconds of delay, but close enough).
The ability to render audio in real time is limited by the processing power of the system you are using. There is specific audio processing hardware that may be used in a system to processes more audio and applied effects in real time (as opposed to using just your DAW computer's processor only). The more powerful the hardware, the more tracks and audio you can process in real time.
If a system does not have enough processing power to render an audio track in real time, some software will allow the track to be pre-processed (rendered) and saved as a rendered version of the track.
Individual tracks may also be "bounced" to a separate audio file with the effects added, creating a new file with the effects included, taking away the processing necessary for that track.
Processing the audio in real time has the benefit of allowing all the variables of the mix to be changed as you produce the mix.
To change the mix of rendered audio files they would have to be changed and then re-rendered, creating a significant gap in the work flow, which could make it a less desirable process than processing in real time using adequate hardware for the project.
So yes, if the system you are using is incapable of rendering the audio you want in real time, most software will be able to render the audio out of real time for playback.
Most DAWs do have the ability to render audio in a non-realtime mode - often it's called 'render offline' or similar.
You often don't have to take an 'either/or' approach though, because you can often 'bounce' your rendered tracks to audio tracks while you're not working on them, making the effort of producing them in real-time very low indeed. If you want to make changes, you can go back and unmute the original instrument tracks.
