why logic pro produce wave file with chunk id LGWV

greating！

I create my wave file by logic pro ,and when I open it with scipy wavefile read function,warning appears.I debug it and find that the wave file has a chunk id "LGWV",so that the code cannot recognize it .

I suppose the logic pro tag the id with"LGWV",am I right?

and is anyone know how to delete the chunk id LGWV?

Thanks so much!

Total guess here.

You can have wav (riff) chunks that are application specific. - not part of the wav audio designation. I suspect those chucks contain info specific for logic. -hence LoGicWaV - those chunks should be ignored- so probably a coding error In the API

Is this from a bounced wav file. Anyplace you can post an example for download.

Possibly something to do with Apple's loop format?
