I would assume that the byte order
Oh well. So now the "official" code looks like this:
#include
unsigned char * in; //point to buffer returned by cd_read_audio
#if __BYTE_ORDER == __LITTLE_ENDIAN
short input = (short)(in[0]|(in[1] << 8));
#else
short input = (short)(in[1]|(in[0] << 8));
// ?? didn'
Thanks everybody for the help. To bring the topic to an end, here is the code
that works:
#include
unsigned char * in; //point to buffer returned by cd_read_audio
#ifdef __LITTLE_ENDIAN
short input = (short)(in[0]|(in[1] << 8)); // PC
#else
short input = (short)(in[1]|(in[0]

Well, that doesn't seem to work for me. If I use "s16" instead, it s
