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 FirstQuality 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 Seedsection 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 ControlAfter 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 NamingName 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 FingerprintingThe 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 FileAn 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 ProblemsSometimes 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.
