STATISTIC SHEET
The Mix(ing) Challenge has a certain distinct
set of rules regarding submitting an entry.
As in: mix in such a way that there are barely any changes needed in a follow-up mastering process, don't exceed certain loudness and maximum signal strength limits, export in the same sampling rate and/or bitrate that the material was provided in (bar minim at 24bit), properly name your entry (filename template) and use your forum username, and finally, document your edit.
The reason behind all of this is rooted with the educational aspect of our community: learn how to pay attention to detail regarding requested specifications and/or special tasks. If you didn't, yet still advanced into the next round, that would have been unfair to every other participant. So the Statistic Sheet mechanic was re-introduced in July 2020 to not only neutrally enforce the game's
rule book, but also to offer an additional learning aspect, to improve on your skill-set and possible bad mixing habits. And with the Mix(ing) Challenge, you can experience this learning process is casual manner. Before you might run into such tasks in the real world (with actual paying clients), and then run into trouble.
Here is the Statistic Sheet for Mix Challenge MC084 / February 2022, as visual example for this addendum:
MC084 / February 2022 Statistic Sheet - full sheet
What does the Statistic Sheet tell you?
The Statistic Sheet is offering you a simplified analysis in written form for the entry you submitted. This check is handled by the staff after the initial submission period has ended, and before the the Mix Round 1 Evaluation starts. For analysis, Wavelab 10's "Batch Analysis" tool is used, which utilizes EBU R-128 specs (equivalent to ITU-R BS.1770-4). The results are a custom layouted Microsoft Excel/Apache OpenOffice sheet (manual labor).
It focuses on the following (corresponding with the columns in the PDF files):
Additional Info
A lot of participants look at this column first, as it provides a quick summary what went wrong, or what one should look out for.
- file not accessible -- unable to download entry (either broken link, expired link, log in required, etc)
- re-submission (date) -- proven re-upload of an entry. If both files are available for analysis, the re-upload will also show up in the re-submission at the bottom
- filename template -- provided filename template was not used, or the filename has been turned around in some way
- username association -- your entry could not be associated with your forum user account
- no documentation -- you didn't provide at least rudimentary documentation of your mix (like: why you went for a certain particular sound, or explaining a certain sound you were proud of sculpting, etc). A lack of documentation results in your entry being "tagged disqualified"
- wrong sampling rate -- your entry was exported in the wrong sampling rate
- wrong bit depth -- the bit depth of your entry is not correct (bar minimum 24bit)
- loudness specs -- either your signal exceeded the maximum allowed signal strength (-1,00 dBTP), maximum allowed average signal strength / loudness (-16,0 LUFS ILk), or undershoot the minimum allowed average signal strength / loudness (-24 LUFS ILk). Tolerances taken into consideration
- warning: ??? -- a general warning what to look out for. Like rogue peaks, over-shots, song length, etc
Disqualified
The second-to-last column only shows two types of markings, or no marking at all.
- no marking -- your entry is within given specs
- a bold "X" -- showing that your entry has been "tagged disqualified", but can still advance into the next Mix Round with the help of a Wild Card.
- a bold "OUT" with a red background -- indicating your entry is "out of the game" and can not advance anymore
Filename / Forum Username:
The sheet lists your forum username in this column. If you didn't use the provided filename template (always provided in first and second post of each game thread), or even worse, your submitted file could not be associated with your forum user account, your entry will be marked as such. Two more ways to get the same color, is if your entry could not be downloaded by the end of the game's deadline, or if you've re-uploaded your entry (your submission is final, re-submissions are not allowed).
- in case of the filename template not being used,your entry will be "tagged disqualified" (this might change in August 2023 to tagged "OUT")
- in case of no associated username, or file not being downloadable, this is the criteria where your entry is fully considered "OUT" (as in: out of the game), with no further chance to advance in the next mixing rounds. The used background color will be red.
Sampling Rate:
This column shows if you've paid attention to detail regarding the source material. If it was in 44,1kHz, 48kHz or 96kHz, you should have submitted a mix/an edit in the same sampling rate to prevent unnecessary sampling rate conversion, affecting the audio quality.
- Mismatching the sampling rate results in an orange-toned background marking, and your entry will be "tagged disqualified".
Bit Depth:
This column shows if you've paid attention to detail regarding the source material. If it was in 16bit, you should have submitted a mix/an edit in at least 24bit. If it was in 24bit to begin with, then only submit in that bit depth, etc. This is to prevent unnecessary bit depth conversion, which can result in unwanted noise and audio artifacts.
- Mismatching the bit depth results in an orange-toned background marking, and your entry will be "tagged disqualified".
- If the bit depth drops lower than 24bit however (due to low maximum and/or average signal strength), then the readout is marked with a grey background as a bonus information. No penalties in this case.
dBTP (L / R) -- maximum signal strength in dB True Peak (channel independent):
This column shows the maximum signal strength of your provided entry, channel independent for the left and right channel respectively. You are tasked to not exceed a certain value (-1,00 dBTP max). Tolerances due to offsets with other analysis tools are taken into consideration.
- Exceeding this value (-1,00 dBTP max), results in a blue background marking, and your entry will be "tagged disqualified".
- If the readout drops below -6,00 dBTP, then the value is marked with a light-grey background as bonus information (this also has influence on the bitrate readouts and is no reason to worry -- you just didn't use the full bit range). No penalties in this case.
- If the readout is still within the allowed tolerance, only the numeric value will be blue, indicating "you should look out for possible over-shots".
Integrated Loudness ILk :
This column shows, if your entry has been in the allowed target loudness range and/or does not exceed the maximum allowed loudness (-16,0 LUFS ILk max). Headroom is important for follow-up edits and/or transferring the material on to another medium in question (Tape, Vinyl, MP3, Broadcast, Stream, etc). Tolerances due to offsets with other analysis tools are taken into consideration.
- Exceeding this value (-16,0 LUFS ILk max), results in a blue background marking, and your entry will be "tagged disqualified".
- Undershooting this value (-24,0 LUFS ILk), results in a darker blue background marking, and your entry will be "tagged disqualified".
- If this readout is still within the allowed tolerance, only the numeric value will be blue, indicating "you should look out for possible over-shots/under-shots".
Mix Length
This column is currently for information purposes only, but might turn into a future "tagged disqualified" criteria.
This readout shows whether or not you might have cut the edit a bit too short. It is always recommended to at least render with one bar (measure) of silence each in front and back of a production, to not only prevent transient smearing at the beginning of a mix, but also offer follow-up edits a proper way to create fade-in/fade-outs.
- This field is marked in in a light-yellow color tone if your export is shorter than the acceptable song length (without silence in front/back).
The Statistic Sheet is also forwarded to the Song Provider(s), giving them a quick and easier overview as to quick entry "played by the rules", and which didn't. Those that didn't and are merely "tagged disqualified" can still advance through the help of a
Wild Card - should the "client" like your entry and wants to see you in Mix Round 2.
Please read the follow-up post on that topic.
