I'm not @aran, however I hope you don't mind me answering your question.
I've got the answer from SoundCloud a while ago that this feature doesn't exist anymore if you're uploading from PC however if you still use the SoundCloud audio app there's still a feature to do so. You can see details In this post and here are the instructions on how to do direct recording on android app. I honestly don't know what takes to do the same on any iDevice though.
Hope it helps at least a bit.
If you don't have other option but PC or laptop. then you'll just have to pre-record everything first and upload to SoundCloud afterwards.
