...re is no official limit.
I was under the impression that 8 was the limit. Thus the extra white
space JM adds on Speex and CELT magics. I may be wrong, though.

So char[7]: '\x01vorbis', char[7]: '\x80theora' and char[5]: '\177FLAC'?

I don't think that interferes with anything. We are talking about the
essential part needed to be detected by applications.

What is the magic code for Ogg FLAC?
Hello,
I just noticed that ogginfo is not properly detecting Ogg FLAC files.
To fix the issue I will need to know what is the correct magic for Ogg
FLAC and how big are the packet bytes.
Please advise.
