You need to pass the data in whatever is the native endian-ness

Using libsndfile (I am the author):

This is not right. Some file types are little endian (WAV for example)
others are big endian (ie AIFF). There is hwoever also a big endian
WAV variant (RIFX) and some AIFF files contain little endian data.

libsndfile handles all the above variations correctly.
