Guidelines For Seeding A New Show
[WheelToTheStorm] flows with TradeFriendly music mastered at the show, as well as donated from the community. The long document below takes you through each step of preparing your donation- your seed- for proper distribution as FLAC files. What is covered:

  • Quality Control
  • DAT Transfer or DAE
  • Tracking (Aesthetics and Sector Boundaries)
  • NamingStandards
  • Compression and Fingerprinting 
  • Info File 
Note: All music circulated through WheelToTheStorm must be TradeFriendly. Please see AboutWheelToTheStorm for why this is crucial. If your seed is not fully permitted to trade, I don't want it.

Quality First

Quality is very important to the members of our community. Before you seed a show, please consider this question: Is this the best possible source? A copy of a show may circulate to hundreds or thousands of people over time, each of which will spend time and money sharing, burning, and listening to a show - so it's a very bad idea to put an inferior seed into the trading pool. Do some Quality Control:

  • Check around for best-available copies within the trading community for your band, and consult available references. Sometimes fans maintain circulation guides.
  • Visit the ShnDatabase. This resource lists many performances that have made it into lossless format already. Will yours be an upgrade? Don't just duplicate previous efforts.
  • Listen carefully to your show. If there are flaws in your copy, are there flawless sources available? Do a little research into the recording's lineage, contact the person from whom you got it, and make sure that the flaws on your copy are on every copy in that line. If not, you could use a new copy as well!
  • Do not start with source material from lossy compression such as mp3, mp4, or aac. It has already lost some frequencies that cannot be regained. Instead, track down the original .wav source from which the .mp3s were made. You might want to do a little source analysis on a couple sample tracks of a show to see if what you see is consistent with the type of source you're supposed to have; and to see if the transfer was done properly.
  • Quality is much more important than speed. Take your time during seed preparation to do a careful job. Don't let all the people begging to get a new show lead you to cut corners - once a quality show is out, they'll forget the wait. The wait is temporary, flaws in a seed last forever.
  • Do not seed EAC rips of already existing lossless sources. Adding DAE generations is frowned upon and has potential for loss of quality.
  • Alter source text files for existing lossless sources with care. Please do so if you have also made a change to the source itself. You can also update source text files to correct or expand on source/lineage information and track listings.


Transferring Your Seed

section redraft in progress, excuse raggedness
Seeding starts with getting your recording into a format for electronic distribution. This involves "transferring" your material to a computer, changing it to 44.1kHz sample rate for CD if necessary, listening to the audio for a quality check, tracking it for CDs, compressing the audio data into a LosslessAudioFormat, and creating the necessary companion files for your seed, including an informative "info" (txt) file. Recordings are sometimes seeded from burned CDs, in which case the DAT transfer and tracking steps are replaced with a careful digital audio extraction (DAE) step. However, seeding directly from DAT is strongly preferred whenever possible.

If possible, capture and edit the files in 24 bit audio. Save the step of downsampling to 16 bits (required for CD audio) and dithering for the final step. Be sure your audio editor does a proper dither / re-dither!

From Laptop No "transfer" step since recording occurred directly to computer, but recording may have to be downsampled for 44.1kHz audio CD format. References: [24-bit FAQ], [laptop-tapers]


Tracking the Seed for CD

Aesthetics
You should arrange your seed into tracks in a way that gives a pleasant listening experience. "Buzzkill" careless tracking of seeds is a common complaint from listeners; a little extra thought brings a lot of happiness. If the recording came from a DAT, you'll now need to track it for audio CDs from scratch. If you're seeding from a previous CD, you can optimize the tracking at this point, if necessary. Here are some tracking tips:

  • Place inter-disc cuts at a quiet spot in the performance (preferably at a set break, or at a pause between songs) and not in the middle of a killer jam. This sometimes means leaving a disc only partially filled so that all the segues are together on a disc. It's more important to have the music hang together cohesively than to have totally-full CDs. Discs are relatively cheap.
  • Find appropriate places in the performance so that it will fit on standard 74-minute CDs. 80-minute discs are plentiful and widely available now, but not everyone uses them. If you want to keep everyone happy, try to keep the discs to 74 minutes or less. (Though at this point, this is far less an issue than it once was, especially if it means fitting a show on one less disc.)
  • If crowd noise or a spoken story is present between tracks, track it so the crowd noise is at the end of one tune, not at the beginning of the next. (If it's a really long story, consider tracking it as a separate track.) This way, eager listeners can skip right to the beginning of a song instead of waiting through some cheering. However, if there is a short kick-off or an introduction to a song, consider putting it at the beginning of the track. Don't cut off any musical notes at the beginning of a song, even if there's talking or intro over them.
Tracking at Sector Boundaries
Paying attention to a simple technical issue during tracking can make a noticeable difference in seed quality. Each track of a standard audio CD is composed of "sectors" or "frames" that are each 1/75 second long (also expressed as 2352 bytes or 588 samples long). If a track is properly cut on a multiple of 1/75 second, it is "sector aligned", or cut "along sector boundaries." When it is not properly cut, the last sector is like a ragged end, which CD burning software just fills in with silence. Listeners will hear a click or pop between tracks because of the music -> sub-second silence -> music transition. This is extremely annoying and easily avoidable. Here are some sector boundary tips:

  • To avoid sector boundary errors (SBEs), just use the right tool in the right way to do your track splits. The simplest and best tool for tracking a show is [CD Wave], for Windows. The program's sole purpose is to split .wav files into proper CD sector-aligned tracks. The interface is very simple and easy to use. CDWave does not delete your original wav file; instead, it generates a separate set of tracks. Also, you can save a cue sheet with the split points for the tracks. This allows you to generate a set of split tracks and see how you like them, and if you decide to make changes you can go back and generate a new set of tracks from the original long wav file.
  • Most audio editing programs (e.g., Sound Forge, Cool Edit, etc.) do not automatically cut files along sector boundaries. Either change their settings to force them to split .wav files correctly (to cut on a 1/75th second CD sector boundary), or avoid them for CD tracking.
  • For the Mac, there is no direct equivalent of CD Wave. Dave Mallick notes, "[SoundEdit 16] is quite capable of splitting a transferred DAT into tracks. Just set ruler units to frames, set 1 second = 75 frames, and have at it. As long as you enter a whole frame value into your selection box, you get perfect sector boundary cuts every time." This is also the case for [Felt Tip Sound Studio].
  • Do any editing or "mastering" before doing your track splits. Never add fades or edits to .wav files after you track them. Doing so can push them out of alignment.
  • An easy way of checking for sector boundary errors is by use of [shntool]'s len function. If you see a -b- flag next to the listing, that indicates a boundary error. 
  • For Linux (UNIX), there is a program called [wavbreaker] that will allow tracking on correct sector boundaries.
  • For Unix, there are two programs called [cdrdao] and [gcdmaster] for tracking CDs. gcdmaster comes in handy because writing toc/cue files for cdrdao with a text editor, by hand, is usually slightly boring at best and frustratingly tedious at worst.
  • If you are reseeding, recent versions of FlacFrontend have a working "align on sector boundaries" feature which can repair improperly cut files.
  • SBEs will sound louder or softer depending on the CD player. They may be very loud and annoying for some listeners, even if they are not noticeable on your own system.


More Quality Control

After you've done your DAT transfer or DAE, you should listen to the resulting audio files on disc or on your computer to ensure they are clean. There should be no clicks or pops that don't exist on the source media, and the overall sound quality should be the same as the copy you're working from.

Please take the time to listen to at least some of the material you transferred (e.g., a sample from each DAT or CD). Ideally, listen to your recording in its entirety. If it's a killer show, you probably want to hear it again anyway :-)


File Naming

Name your new .wav files according to etree.org's basic NamingStandards. They will now be ready for compression into a lossless format. Typical compression tools will take the names of the new .flac or .shn files directly from the names of your .wavs.

Compression and Fingerprinting

The audio .wav data you have created should next be compressed into a lossless format. Compressed files will be easier and faster for people to transfer around, and to store as archives.
FLAC 
FLAC is a proven and more modern format, with several important advantages over other lossless codecs. Tools available for compression to .flac are listed on the FLAC page.

You are strongly encouraged to add tags (also known as FlacMetadata ) to the files. Unlike shn, but like most other modern compression formats, flac has a section of the file which stores information about the file. The comment field allows you to identify lots of information about the show, gear, encoder, etc. That means no more mystery files or versions! The track name and number is used in many flac players (both hardware and software players).

Place the .flac files you create into a new directory that conforms to our NamingStandards

You should create a FlacFingerprint (ffp.txt) file for your .flac set, using NamingStandards. This file will help future traders identify which flac set they have for a given show date. See the FLAC page for software links; the FlacFrontend program can generate a fingerprint file, for example.

(Side note: Whether to include whole-file .md5 fingerprints as well is a topic of debate.

Creating an Info File

An info file is a plain .txt file that tells people about your seed. Often it's the only thing a potential listener has to help him decide whether or not to download or trade for your fileset versus another fileset. Since downloading and trading take time and effort, the more details you can give, the more you will help the decision. Here are some info file tips:

  • Create a new file in a text-viewing program (like Notepad, Wordpad, Windows, etc) and start typing and/or pasting from your reference material. Include info as directed below. When done, save as plain text, not a fancier format like .doc, so that anyone can read the file on their own platform.
  • Include the band name, date and venue.
  • Include source information that is as complete as possible: full genealogy, DAT transfer method, etc. This greatly helps the many people who know how to interpret source info. In contrast, having very sketchy info will cause many traders to shun your seed. Feel free to ask your trading partner for more info, or his trading partner...
  • Include a track listing with disc and track numbering, song titles, and ideally track timings as well. If you don't know the song title, leave a ? next to the track number- someone may be able to fill it in later.
  • Add track and disc timings to help people decide what length disc to use (74 vs 80 min), whether or not to move songs between discs to their taste, whether to add filler, whether to use one of your tracks as filler, etc. 
  • Add any observations and notes. Point out flaws or splices, and any need for 80 min discs. People appreciate being forewarned.
  • Feel free to give credit to others, especially the generous taper(s) who made the recording (unless they wish to remain anonymous).
  • Take credit (and responsibility) yourself. If you produce good seeds, people will look out for your name in the info file, as a mark of quality. Add your email address if you like, so you can help address any problems that might come up.
  • Do NOT place restrictions on what people can do with your fileset. Once you release it, it's in the public domain, subject only to the band's trading policy. Not only are "restrictions" like "Do not convert to .mp3" and "Do not remaster" completely unenforceable, but they are obnoxious, impractical and go against the spirit of the community.
Name the .txt file according to our NamingStandards and place it in the same directory with the other files. Within the directory you made, you now have a complete "flac set."

If There Are Problems

Sometimes there is a problem with your seed that is not detected until you've put it into circulation. For example, a .flac file may have gotten corrupted during your initial upload or even (rarely) during your compression step. There may have been a mistake during DAT transfer. In some cases, others can fix minor errors and reissue your seed as a fixed copy. In other cases, you are the best or only person who can fix the problem. If necessary, please give the problem that extra bit of your attention, so that your overall effort of seeding won't go to waste.
