I have some bootlegs from the old trading days when shn-compression was the commom lossless compression. (As I remember it flac became available and popular only later on.)
Do you think it is better to convert those shn-files to flac if I want to share them here (adding one step in the lineage although it should not matter qualitywise) ?
I think flac is prefered today and most people do also use the flac-files for listening to the music on their computer.
Is there something I should take special care of when converting those files to flac?
Thanks for your help!

Personnaly I would prefer when you uploaded as shn, maybe with a link to the software to convert. Converting to wav and then to flac is an extra step in the process with possible downgrading of the material.

yes , what a sinchronicity  , I was going to ask the same. I know that some purist will bitch you if you do that, but some day or another someone is going to do it...I suspect some PF or U2  btw, Trader's little Helper is a good decompress tool  The only bad thing is if other guys dl the same shn and you do that, (shn...wav...flac) the guys could not help you, cause the flac-unflac process (the packageing) is never the same, waht is "inside the package" yes..sorry, no idea how to explain it ...I tell you, I´m sure. Even flac...wav...flac you don't get the same flac, that's why all we backup our flacs...well, that's the idea  It's up to you... |

 If I gave you everything that I own and asked for nothing in return Would you do the same for me, as I would for you? Or take me for a ride and strip me of everything, including my pride But spirit is something that no one destroys |

I can see no problem with converting lossless to lossless. The very idea of using lossless in the first place is, well, that it is lossless. No data lost between the conversions, in other words. I do believe that FLAC is preferred these days. There may of course be tools that introduce errors, though, but I am pretty sure that Foobar2000 and dBpoweramp (Reference R12) are not among them, and they both make the process easy by doing that conversion to .wav in the background - what you see is a conversion from X to Y, in this case .shn to .flac. Now, a personal opinion. If you are going to convert files so that people with the original files can't help seeding them anyway, why not take a look at the tags, too? It takes very little time to load an album in, for example, Tag&Rename and check/fix the tags - it automatically chooses Ogg Vorbis/FLAC tags for .flac files. Edit: Btw, I would recommend using the highest possible compression level, 8, since it results in the smallest FLAC files possible while of course retains the lossless quality. The one drawback is that the compression takes slightly longer than it would if you use a lower compression level, but IMO that's worth it because of the advantage in sharing the files. |

I tell you man, no one with the original shn or flacs (flac...wav...flac) could help you after the process. but that's not an important issue, if you have a good ul speed, and that's ss case , but not mine  |

I was especially thinking about you goa as I have read that you don't like shn... (so no PF or U2 this time ) And I was not thinking about that anyone would help me seed this. I understand your point in this goa but this time it is different. I understand that the software could introduce some errors when decoding the shn file. It would have been great to have a md5 of the original WAVE-files for that, but there was none with those files. Yes flac-tags are very nice. I did them with my own rips. But if I get flac-files from "another tracker" without tags and then insert tags I think the original md5- and fingerprint-files won't work anymore... btw. Fingerprint File a great Rolling Stones Song... |

Hehe, just edited my post about compression.
But I have to reply to this. The flac fingerprints will be the same even if you re-tag files, unlike md5 sums. That's the genius of the fingerprints: they are just for the audio information.
But, of course there is a problem with adding tags to files you have recently downloaded: they will change the hash values of the files, so you can't seed after changing the tags. Personally, I make copies so that I can both keep seeding and tag the music the way I like it.

fine. Anyway , I'm not talkin about errors. Just the "package" (shn, flac) or wahtever is everytime different. and...waht's the diffrence of md5 (yes, anychange ruin the checking, I learned that yesterday )and fingerprints what porgram use for that, TLH helps |

Borrowed from the Etree Wiki: Unlike an .md5 file, the FLAC Fingerprint ffp.txt file itself is not actually used in performing integrity checks on .flac files. Instead, when you decompress or use flac's Test feature, FLAC automatically verifies each file against an internal checksum stored in the file.
(...)
A FLAC Fingerprint is generated only for the audio data portion of the file. (Therefore, changing the filename or the tags or FlacMetadata does not change the fingerprint calculation.) In contrast, an .md5 is generated against the whole file, including header portions. Genius, I say. Oh, and you can generate fingerprints for your FLAC files in the FLAC frontend. Very easy, select the files and click and save to a text file. |

 I did not remember that. So could have done with all my uploads...  I use a Mac and do all my flac-work with xACT 1.59. It is said to be the best for OS X. And I think there is no version of Traders Little Helper (Mothers Little Helpers ), Foobar2000 or dBpoweramp for my platform available. Still I am a bit concerned to do the conversion as stefan said it would be a downgrade. (And the shns are the "originals" from the taper...) And which software does decompress shns on the Windows platform? (I am an OS X dummie... )

I insist ss, there is no downgrade, imo. And flacs do an internal check, so "si yo fuera tu", I would ul in flac |
