Stereo tracks

Win 10, Audacity ver 3.1.3
Is it possible to record a separate left and right channel and combine in one audio file for playback?

Does this give you what you need?

Thanks for the reply. I still cannot record separate tracks. I am trying to record two separate frequencies, 440 and 444 hz. One in left and one in right.
then save that file. I can then play the file and I will hear two separate frequencies, one in each ear with headphones.

Why not generate them rather than recording?
“Generate menu > Tone”

Generate each tone as mono tracks, then join the two tracks to make a stereo track.
