Is it possible to test long files with aecmos?

[ahikaml]

I noticed that all files in aecmos_local.py arecut to max_len (20 seconds).
On the other hand, the test set contains files much longer than 20 seconds.
I'm wondering whether it is a real limitation in estimating scores for long files or if it's just a part of a toy example which doesn't mean much.

Thanks
