Hi guys,

I hope this is the right place to ask this question. I need some help in figuring out a way to put the apple loops metadata (tempo and key) in the filename. Here's the thing.

I want to use apple loops in another DAW, but I want also to know their tempo and key. So, what I'm planning to do is a) convert the .caf to .wav b) write the tempo and key in the filename. I need help on the second part. Anyway, idea how I can have access to that info? Or any workaround?

Thank you.

Here's the specs:

It looks like headers all the way down! :lol: But you'll be able to find the chunk headers and pull any necessary data from them.

Are you using a pre-rolled conversion tool? There might be others out there that makes this info available. Otherwise, you might just want to roll your own to do the conversion and rewrite the filename for you all in one pass.
