Audacity openeing screen does not look the same as on you tube help videos

On Youtube , the audacity opening screen shows a box to change bit rate in the bottom left of the screen and towards the top of the screen it shows a drop down box that says MME, BUT I cannot see either of those boxes on my opening screen. It says its version 3.6 Should i be looking at a different screen somehow ??? Thanks Jimmy

Audacity is updated frequently and most people who post videos usually don’t update their videos.

The Audacity help/support pages and User Manual ARE usually up-to-date.
