View Full Version : SHN Tool "3" Problem (ID[3]v2 tag) Matter?

So I'm about to archive a DVD full of shows, and wouldn't you know it the last show in the batch has the following shntool output:

I've had issues with shns before where I had to remove the ID tags in order for them to work properly but these flacs don't seem to be problematic.

I decoded the first 5 tracks to wav and it worked fine. Then I re-encoded those wavs to flac and the tag error no longer showed up when I checked them with shntool. And the fingerprints are still the same.

So my question now is if should I do this to all tracks to get rid of those tags or does it matter since the files still play and decode fine?


I miss the SBE University days. :cool: :wave:

Well I decided to decode and re-encode all the files to get rid of the error.

Still curious what the shntool experts think about it...

A '3' in the first slot indicates that the file contains an ID[3]v2 header.
really not an error per se

I never had this problem but foobar should do the trick without having to reencode.

It's probably best to remove them...from the FLAC FAQ:
Out of convenience, the reference decoder knows how to skip ID3 tags so that they don't interfere with decoding. But you should not expect any tags beside FLAC tags to be supported in applications; some implementations may not even be able to decode a FLAC file with ID3 tags.
Decode/re-encode is probably unnecessary...foobar (or another app) can probably just remove the id3 tags.

Actually, I think shntool itself can fix this problem--I know it can remove headers that aren't the proper size and extraneous RIFF chunks.

Humor me and see if this command would also fix the problem:
shntool strip *.flac

(I think you can use wildcards with this command--if not, you'd have to do each file individually and it wouldn't be worth it.)

Thanks for the input. I've already deleted the original flacs, so I can't try foobar or humor you Sarah.

I hope this helps, Sarah.

Yeah Sarah.
