I'm trying to watch 2 Youtube videos at once on Windows 7 using a headphone by directing the audio from the 2 videos into 2 different ears. I.e. the audio from one video only uses the left channel, the audio from the other video only uses the other channel. This way, I can watch 2 videos at the same time. Is there a software that can accomplish this?
You could use two windows of VLC, go to Open Network Stream (CTRL + N) then go to Audio - Audio Channels - Left/Right
