File is decodable without error, but flac fingerprint cannot be checked since it was unset in the streaminfo block.

Hello i need some help, i want to decode a flac file and appear this message in TLH:

File is decodable without error, but flac fingerprint cannot be checked since it was unset in the streaminfo block.

i don't understand quite right what it means.

Any help is much appreciated
Thanks

When a wav file is encoded to flac format the flac encoder writes the md5 checksum of the raw wave data (the so called flac fingerprint) to the header of the flac file. When decoding that flac file at a later time the integrity of the audio data will be automatically checked by comparing the checksum of the decoded wave data with the fingerprint in the flac file header.

In your case the checksum/fingerprint in the flac file header was set to zero (possibly by some bad encoder). So it is not possible to tell whether the decoded wave data is identically equal with the one before it was encoded.

Ok Robert got it! thanks so much of the info.

btw i hear the tracks (decoding throug errors) and works fine.

Re: File is decodable without error, but flac fingerprint cannot be checked since it was unset in the streaminfo block.

I too have a folder where I get this "flac fingerprint cannot be checked since it was unset in the streaminfo block" message. It came with a seperate MD5 file that does verify for all the files in the folder. about 2/3's of the files get the above error message, when decoding.
So are you saying that a flac fingerprint gets written to the encoded file? That fingerprint is missing and there for the data can't be checked? That the seeder made the seperate MD5 after he encoded the file with the fingerprint missing? That's why the seperate MD5 file does varify?
Thanks
MIke

Don't mention it, I've not told you anything you hadn't already worked out.
