I wonder if there is a way to read or convert little endian numbers
in ocaml. I am trying to write an interface to WAV audio files, and their
headers contain vital little endian numbers (as well as some
big endian characters)...
thanks

Your best bet is to read byte per byte and reassemble words yourself:
let input_int2_le ic =
let b1 = input_byte ic in
let b2 = input_byte ic in
b1 lor (b2 lsl 8)
let input_int2_be ic =
let b1 = input_byte ic in
let b2 = input_byte ic in
(b1 lsl 8) lor b2
and similarly for 4-byte integers.
