Efficient way to load external data?

I have built a game based on the audio visualization plugin and just found out today it cant be packaged so it looks like all my work was for nothing.

I have only two audio tracks that need to be visualized so my idea was maybe to run the plugin and store the data in a file / database and then simply load those files instead of getting the data directly from the audio plugin.

I just did some php in the past so this will be really challenging but I dont want that all my work was for nothing so if you have any pointers how to get this going please let me know.
