How can I record audio only? Is it possible to create mp3 file?

[MarS8]

I am quite new in using this, and very happy for advice!
My wish is to do good quality mp3 recordings from a radio website and / or video conferences.
Thank you!

For recording audio only OBS isn't your best choice. You may want to give it a try to Audacity which is one of the best audio apps out there.
