I'm trying to determine what data should look like when it is
unpacked. I think I understand it now, but I'd like some
confirmation.
Say I have a 20-bit sample: 0xABCDE that needs to be stored in a
32-bit audio stream formatted as below:
aligned high& little endian: 0xABCDE000 aligned low& little
endian: 0x000ABCDE
aligned high& big endian: 0x00E0CDAB aligned low& big endian:
0xABCDE000
Is this correct?
No.
Would you care to enlighten me?
Try http://en.wikipedia.org/wiki/Endianness
and NB: byte-reversal reverses the order of bytes, not bits or nybbles
within a byte. You are approximately back to front (or front to back;
but not trorf ot kcab) in your ordering.
