Title: What is this error message?
Post by: plucks on May 15, 2003, 04:27:30 PM

I am encoding some files to FLAC and i get an error message that says:
"WARNING: Skipping unknown sub-chunk 'PAD'"

Any ideas?  It keeps encoding and seems to work out ok

This happens when whatever program you use to save writes 'useless' information in the file header, pads it, or otherwise has a non-standard wave header. FLAC only encodes relevant information and has defined criteria for the header, the specifics of which can be found on SourceForge.

So, is this bad?

Nope, it's just letting you know that it killed part of your header. The wave data itself is still the same. Your decompressed wave will be the same as the original, however, the header data will be slightly different.

I don't know of a program off hand that lets you look at a wave header, but if you could do that, you can see what the exact header differences are between your master and the decompressed FLAC.

Again, I must stress that none of this affects the wave data itself.
