ffp = shntool md5 = st5 ???
Are flac fingerprints and shntool md5 and st5 all the same thing? I'm getting the same hash for them all. So is it redundant on a flac show to make fingerprints and an st5? And if an shntool md5 and an st5 are the same thing, what's the best way to name it, with the st5 extension or shntool-md5.txt?
Thanks. No members have liked this post.

Re: ffp = shntool md5 = st5 ???
Um, yeah, kinda.
They all give you the same hash, as you can see. That's the whole idea. We want to have one fingerprint/hash that will be identical whether a show is in flac/shn/wav/aiff/whatever format. So, yes, fingerprints and st5s are the same. The thing is, no one has come up with a standard extension for shntool md5s, so people are coming up with their own. shntool and xACT make them .txt files (I think), but TLH makes them st5 files and Stephen's makes them something else. But, they are all the same.

Re: ffp = shntool md5 = st5 ???
I wonder then why when I make ffp with shntool it happens almost instantaneously and when I make shntool md5/st5 it takes a little while... ?
So really I just need to make the ffp then anyway I guess, so I'll save some time. This shit is starting to really take a long time to archive stuff with all this checking and fixing and converting... why do I listen to Stephen and Jamie??? No members have liked this post.

Re: ffp = shntool md5 = st5 ???
Flac calculates the fingerprint as it doing the encoding and stores the md5 checksum in its metadata header. When you make an ffp it is simply retrieving that value (real quick). Shntool-md5 takes longer because it must decode the file and calculate the md5 of the decoded data.

flac's metaflac command does the former, so it is very quick; shntool actually generates a new md5 so it takes longer. shntool's method is technically a safer way to do things, because it is conceivable that a flac file could be corrupt in a fashion where the stored footprint is still extractable from the meta tags, but the audio data has been changed somehow.

------------------------------------------------------------------------------------- Flac Fingerprints previously posted by uhclem: I use a simple batch file to create the fingerprint. It's simple because you just drag 'n' drop the folder containing your new flacs onto the batch file and voila it produces a fingerprint file for you in the folder. Here's the batch file I use: @echo off %~d1 & cd "%~1" for %%F in (*.flac) do metaflac --show-md5sum --with-filename "%%F" >> "%~n1-ffp.txt" ------------------------------------------------------------------------------------- It makes a flac ffp.txt file in the folder.

It is adequate to generate a .ffp (if there isn't one already) and drop the FLACs in FLAC frontend and run a test to make sure the data isn't corrupt. So what you really need to do when you get a show is: -run a test using FLAC frontend (or a batch file, etc ) -run a shntool len check (for SBEs, also to check the audio is 44.1kHz/16bit, etc.) -have a peek at a couple of the files in a WAV editor like Audacity/Audition checking the fa and sa to see if the source looks suspicious (i.e. lossy-sourced). -while you've got the files open in a WAV editor zoom in on the beginning and the end of the tracks to look for any TAO/SBE gaps printed into the audio that could not be detected by a shntool len check. -generate a .ffp (if there isn't one already, works with FLAC only) -generate a .st5 (manditory for SHN & APE, optional for FLAC)

Re: ffp = shntool md5 = st5 ???
Did I ever send you the batch file I use to create .st5. Works like a charm!!!
I agree with Five - .st5 are the best way to go. No members have liked this post.

@echo off
%~d1 & cd "%~1" shntool md5 *.flac > "%~n1.st5" exit No members have liked this post.
