The importance of checksum and fingerprints for .FLAC files?
« on: September 05, 2007, 04:20:08 AM »
I personally would prefer the tracks just state the name of the song and not all the date and venue info for each track as it seems to be with releases that have fingerprints or checksum (not terribly aware of the difference).

I don't expect you to explain it all, as I've read a few hours about it and still am only aware of it helping burn the CD faster or something like that.  I just want to ask how important it is for the average person.

Also, I found out about more potential hassle, with sector boundaries.  I use cooledit to edit the tracks, but apparently that doesn't work as well as "CD wave" for ensuring no SBE.  Is this a big deal too?

Neither one sounds too difficult, I was just curious what the preference was of most tapers that seed their recordings.

There is a "standard" for naming wav (but mostly flac) files, it's detailed here:

http://wiki.etree.org/index.php?page=NamingStandards

You'll find the majority of tapers follow this standard; however you'll see many variations on sites like Dime.

The text file that accompanies the torrented FLAC files should contain all the artist, track, equipment info (have a search on this too if you are unsure).

Again, majority of us use CD Wave for seamless tracking of a 44.1 kHz recording.

Fingerprints and check sums are recommended, and obligatory for sites like Dime / bt.etree for seeding shows. Even if you're not intending to seed a recording now, it's worth doing the work now rather than in a couple of years.

Hope that answers your questions?

lol, w/o the proper naming of files, all hell is gonna break loose. How are you supposed to know what order to burn the tracks to a cd or dvd, and I hate it when there isnt uniformity for date labeling. mixing up the day and month is f'n lame. Also I always run md5, mostly just to make sure all the files are good to go and not corrupt.
Seriously, the band makes the music. Tapers just point mics in the right direction and hit "record".

That's good to hear!  The last patcher I had complained about my AKGs, fluffed schoeps for about 15 minutes, stayed patched in, and farted on me all night long.

this is humorous ;D, we should all just start naming them by song or however we want and see what happens. uniformity is a good thing when it comes to naming files.

instead of using the song names in the file name, it'd be far better to use etree file naming standards, AND use FLAC metadata (aka FLAC tags) to get the info shown that you want to see when you play the files back via computer...

In addition to the standard naming scheme you can add meta data to your tracks that list title, etc.  Those will show up on computer playback and most newer CD players.  I think depending on what view you are in windows even shows you the data in explorer.  MD5s are good so you know your download completed without error (but is a little pointless for torrents since bittorrent takes care of it for you.)  FLAC fingerprints are just a good way to visually check a source to see if it differs from another without downloading it.  Each FLAC track actually has error checking built in so you can 'test' the track without the fingerprint to make sure it is OK.

FFPs and MD5s:  These insure that the files you DLed are "authentic".  If the MD5 you have matches that of the original, you know you have perfect copies of the original.  Also, with you are able to verify if your files have any errors.

ETREE naming standard:  This has slowly become obsolete.  I started a small discussion on the ETREE Forums about modifying the naming standard to combine the iPod standard of "01-song name, 02-song name" and the ETREE standard "bandnameYEAR-MO-DAd1t01, etc". 

But after further thought, I decided that the old ETREE standard is perhaps still pertinent.  If I DL a show that only has song names, and not track numbers, in the file-names, I am unable to figure the proper burning order.  ETREE naming standard insures I know how to burn the tracks properly. 

Also, when I copy over all my FLACs onto my HDD, they all line up in alphabetical and chronological order.  This is really nice...

As for SBEs, you should make the attempt to correct these before you seed.  If you do not, DLer #1 will "Fix" the SBEs one way, while DLer #2 will "Fix" the SBEs another way.  You now have 2x different filesets - although they are from the same exact source, they may produce differing FFP/MD5s.

I tend to fix every fileset I DL so they match the shows that already exist in my archive.  I keep track of the original FFP/MD5 - I copy them into the text file...

Additional uses for FFP/MD5s:  Verify your files after you burn to data-disc.  Sure you DLed without error, but did you burn the data for future use without error?  I've found a few bad burns in my years of saving SHN/FLACs to disc...

Also, FLAC fingerprints should be used if at all possible.  I don't personally use them, as I don't need them yet...  But one day I'll be playing FLAC files > ??? > Stereo, so the tags will be nice. 

The ETREE naming standard is useful for burning CDRs.  Not so much for those of us that use PC based players or iPods, etc...

YMMV,

Terry

i make md5's for EVERY flac folder i ever burnt to disc/dvdr. I just started adding the song titles to the end of each track naming scheme. I like this method betterb than using a tagger.

heres an example and works great for listening from the PC:

aod2007-07-14.483.722_intro
aod2007-07-14.483.722_new_real_rhythm
aod2007-07-14.483.722_bootleggers_advice

it takes a bit longer but is worth the wait.

and ffp files have NEVER saved my ass until recently when i was batch-naming a whole show of files and I screwed up. i went back to the ffp file and could straighten them out and get them back in order thanks to the original ffp file I made.

simply put, JUST DO IT.

That's what I'd like to do.
Why not go with:  BandName_YYYY-MM-DD_01_Song_Name
instead of:           BandName_YYYY-MM-DD_01

This way you can select songs from a folder and know which is which.

By the way, if anybody's still reading this:  Does anyone edit the file information with a Windows OS, where you right click the song and fill in the info fields?  I can't tell where that would come in handy, other than when you were to also right click and check it out.

thats exactly what I do except I include source info in the filename as well

banddate.sourceinfo_songname

works quite well for me :)

I'm a newcomer to the tagging thing, just having gotten my first mp3 player I quickly became irritated with poorly tagged file sets.  Tagging the files is the only way to go.
