Hello everyone!

I'm developing a project on Digital Audio Broadcasting and I need to convert some *.wav file into mp2. The DAB audio frame reuses the ancillary bits of mp2 to carry some information in three fields, Programme associated data (PAD, 2 bytes), ScF-CRC (2 or 4 bytes) and eventually Extended Programme associated data (XPAD, variable). I found that Toolame has an option to reserve space for these DAB extensions but I can't undestand exactly what it does. With the option -D I have to specify a length but this lenght (in bytes?) is related only to X-PAD or also to F-PAD? For example if I put -D 0 Toolame will insert only the two bytes of FPAD and no other ancillary bits? And so if I put -D 2 Toolame will reserve 16 null bits for XPAD, 16 or 32 bits (according to bitrate) for ScF-CRC and 16 null bits for FPAD?
Thank you very much in advance

You are correct regarding FPAD and XPAD, and I think you're right about the CRC, but maybe someone else can confirm this?

thank you for your reply...anyone else can help me?

Thanks again
