I exported a selected track as a .wav file. Before that I accidentally exported all 4 tracks as a .wav file. I knew this because I listened to both of the .wav files. Then I noticed the selected track .wav file is exactly the same size as the .wav with all the tracks. I had to go back and listen to them again to see if I was tired and loosing it. No it is true.
Is this suppose to be like this? These are the instructions I used.
Click on the track panel on the left side of the track you want to export (click below the volume and left-right slides). (the right area highlights blue).
Click file, export, export selected audio.
Choose the directory to save it to and rename the file as the example in quotes below shows.
Click okay on the next prompt.
