I'm using VLC 2.0.8 on Windows 7. How do I play two mp3s simultaneously from the command line (command line because to write a batch script that launches the mp3s)? I've tried
vlc 1.mp3 2.mp3
vlc 1.mp3 --input-slave 2.mp3
(I've seen the second one as a way to play a video file and a separate audio file simultaneously). Both of these just launch 1.mp3.
Not important, but if you're wondering, the mp3s are respectively cafe sounds and rain sounds, so I can play sounds similar to those found at http://rainycafe.com/ without having to launch a browser.
