With libsndfile, converting to float is optional. You can just as
easily read int or short.

Firstly, you do realise that I am the main author and maintainer of
libsndfile, don't you?
Secondly, the scaling can be switched off don't you? See:

Finally, there are about 700 different way so convert between int
and float. I chose the one that I thought had provided the best
trade off. I stand by that decision.
