I could explain how the CDJID is generated (complicated), but it still would
not be of any use. You need to know the track times as they would be
reported by the Sony changer, which can be different than what a CD-ROM or
other device may report.
Still, here's the code - it's based on maximum-length sequences to do some
noise whitening on the data:
const int CDisc::MLSLEN = 127;
const int CDisc::MLS[127] =
{1,0,0,0,0,0,1,1,0,0,0,0,1,0,1,0,0,0,1,1,1,1,0,0,1,0,0,0,1,0,1,1,0,0,1,1,1,0
,1,0,1,0,0,1,1,1,1,1,0,1,0,0,0,0,1,1,1,0,0,0,1,0,0,1,0,0,1,1,0,1,1,0,1,0,1,1
,0,1,1,1,1,0,1,1,0,0,0,1,1,0,1,0,0,1,0,1,1,1,0,1,1,1,0,0,1,1,0,0,1,0,1,0,1,0
,1,1,1,1,1,1,1,0,0,0,0,0,0};
CString CDisc::CalcCDJID()
{
CString t,ID;
int i,j,sum;
if (nTracks == 0)
return "0000000000000000";
for (i = 0; i < 8; i++)
{
sum = 0;
for (j = 0; j < MLSLEN; j++)
{
sum += (track[j % nTracks].TimeInSecs() >> (8*(j/nTracks % 2)))*
MLS[(j+i) % MLSLEN];
}
t.Format("%02X",sum % 256);
ID += t;
}
return ID;
}
