merging multiple audio files sequentially into one file

… I cheat … I put the files on my laptop (that has the headphone stereo 1/8" plug) and run the files through my audio program there on the laptop to my desktop computer_, via Line In,_ that has Audacity 3.1.2 on it (laptop to desktop connected via the 1/8" plugged cable) and record the playlist … I cheat.
