I had a look at the terms (link provided in the issue referenced above)
and commercial usage is forbidden, making the audio files nonfree. Also, the
zip file weighs 87 MB.

Oh, I wasn't aware of #:build-type. Thanks.

I remove debugging information to save space. The ideal case is to move
it to a separate output as in

, but that is something I have yet to take a look at.

I will enable it again in the v2 and add a comment about the data.
