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.
20 bit value: 0x000ABCDE
20 bit value aligned high: 0xABCDE000
so bytes are in order:
little endian (non-aligned) : DE BC 0A 00
little endian (aligned high): 00 E0 CD AB
big endian (non-aligned) : 00 0A BC DE
big endian (aligned high) : AB CD E0 00
