[fpc-pascal] Adding a array of float in ressource and use it ?

Hello.

Some more infos about the problem of our C friends

It seams that for C compilers (Clang, gcc, c++, VS,...) the way to order the
data with a TFileStream differs (not same x-endians) for encoding float.

So you must do it by code and know what compiler was used for the
client-program .

For a file created with a TFileStream of gcc but that will be used by a
program compiled with VS, you should
convert the data from little endian to native ordering (or reverse) with
something like: 

        for i := 0 to nSamples-1 do
        b egin
          PCMIn[i] := (pcm_bytes[2*i+1] shl 8) or pcm_bytes[2*i];
        end;

And this the reason why, for storing data, they prefer to use integer 32 bit
(where it seams that all compilers use the same order).

Voila.

But it is not our problem, so thank for everything and good luck to our C
friends and their endians.
