Hello,

I want to get 16bit value of wave data, but when get wave data I have 8
bit value (e.g: using AVIStreamRead() we have char*).
Is there any function to check data format is Big Endian or Little
Endian ?
I use Borland C++ builder 5, windows2000 or windowsME

Many thanks,
Do Trong Tu

As far as I know, there is only one standard in use for the storage of data
in wav files. I have not heard of there being any issue over little endian
vs. big-endian.

It's little-endian to suit the x86 i.e. treating the data as an array
of words will give you correct signed values.
