[Boston.pm] Perl readable Audio format with embedded timing data

Is there an audio format that lets you take a song and embed command data
to be executed as the song plays?

And is there a perl module that could read/write such a file.

I thinking of embedding some high level commands into music that would
then inform some perl code as to how to generate some constrained
randomized DMX data packets to some lighting.

But I know nothing of audio formats, so I dont even know if its a thing.
And attempts to google fail miserably.
