Ever have that mp3 that seems to start just a little too soon for your show? I guess you also have to be a dumbass like myself and not really know how to manipulate a laser show. I also don't have a program to alter music either but...
I was watching that Mission Impossible beam show from Pangolin, or included with... The music seemed a half second faster that the show. It was on beat, but the change ups happened a half second early if that makes sense. Started to annoy me... Since I don't have an audio program installed and I'm a n00b with my software , decided to try big "Bill's"(M$, not King Pango) bundled software M$ MovieMaker. I imported the mp3, dragged it .5 seconds down the timeline, save movie to computer... It even defaulted the save name to "Audio", asked what bitrate to save it as and saved it as a WMA file, which Autoplay was happy to load with the laser show. It actually took me about 4 tries of dragging and saving before I got the perfect timing, but that shitte is smoooth now.
So if anyone fits the above Criteria, and has an annoying mp3 like the above. Here is a free fix. If you got Winblows.
