eg. genre

i could imagine that you could sha256sum an audio file but that would not be very useful if the wav file was slightly truncated

damo22: musicbrainz supports external links to artists' websites, see: https://musicbrainz.org/relationships/artist-url

Question on "digital release": Nowadays many bands have their records also available for download, e.g. on Bandcamp. Imho if that coincides with a physical realease I would not add that as a seperate release but only in the "available for download" section, or am I mistaken?

well that's what *acousticbrainz* i for.. I think ? :D

or even singing voice detection. Is that something musicbrainz is interested in?

damo22: that would mean EXACT same :)

mckean: there is acousticbrainz for that, it tries to detect tone, mood, bpm...

mckean: https://acousticbrainz.org/813d65f1-fc6f-42cb-8...

pbnoxious: no. a physical release is a differnt release

but in the same Release-Group

e.g. https://musicbrainz.org/release/632a0653-9828-4... was "re-released" on Vinyl but is also found on bandcamp… musicbrainz currently only has it as "digital release": Should I just change it to the correct vinyl or add the vinyl seperately

holy molly... is that opensource?

mckean: YES

CatQuest: so every release has _also_ a digital release nowadays that is distinguished by nothing from the physical one?

pbnoxious: not every surly. but most new ones yes

for a wider overview: https://metabrainz.org/projects

this excites me...

for states like bandcamp it's kinda reverse: it's online but cna *also* additionlaly have cd, casette, vinyl

mckean: yay!

btw, are you all working for musicbrainz?

or contributing?

yvanzo is but i'm only a cat

I am working on mb server

what's the commercial service you provide?

CatQuest: in this case I'm pretty sure the record was on bandcamp before because it is a re-release…

with bitmap and reosarevok

CatQuest: they might have added the bonus track

pbnoxious: re-releases are *aslo* separate releases

CatQuest: don't underestimate the cat!

let me see if i can find a good example

mckean: mrowwrr!

mckean: essentially maintaining the db and live data replication

CatQuest: yes, the link I sent you is already a seperate release for the re-release

oh imissed it

yvanzo: so you rely on donations?

mckean: right, 100%

mckean: donations. but also our yvanzo link them the unicorn page

glad to see it work out!

or donations/sponsors if you prefer

exactly

it's the "drug dealer" business format: we give you *some* data for free. but if oy uwant more (ie faster) yo uneed to pay (this is for big kanhonas liek google and microsft. opensorunce and free stuff cna get special deals)

got it...

every random guy can just set up a replicating database whnever. doesnt cost anything. but if you rely on large data imports constantly

becasue you're a big commercial thing. thn yo ushoudl pay us for our data/bandwith/special deal/whatever

those are sponsors

Out of curiosity, do you go around collecting data or are the big publishers/labels sending them to you?

basically we rely on all our users to import, create and update and fix data

ocassionally we get soem artists actulaly addingthemselves

some times we where paid by bbc to create artist pages too

so many questions... but I'll probably look into accousticbrainz first a bit :)

or rather. individual editors had a contract. that was reosarevok who can explain better thna me about soem stuff

ah for this https://beta.musicbrainz.org/release-group/d36f... the bandcamp re-released physical release. (if it is actually different than) the original should be ti's own release too

is the algorithm for computing the AcoustID public?

sure, it's free software too

NICE

happy to share enthusiasm :)

For vinyl there seems to be ambiguity on how to number the tracklist: either just numbers for all tracks on both sides or adding them with sides as A1 A2… B1 B2…. Can't find anything in the guidelines, what is preferred?

do you provide accousticbrainz as a service?

this is actually simpler than expected...

is there a doc on how the chromaprint works at a high level description? i looked at a few source files and it seems to use an "image" representation of the audio?

it filters, resamples, normalises

removes some noise

hashes the spectra?

when I used it a did it with aidmatch.py

yvanzo: am I correct that the high level data is only provided by musicbrainz when submitting the generated data file?

mckean: not sure to understand your question...

damo22: https://oxygene.sk/2011/01/how-does-chromaprint...

our development channel is #metabrainz if you are more interested into development

mckean: alastairp (AcousticBrainz lead) would be more able to answer your question ^

> The label assigned two distinct labels to mp3 and lossless downloads at https://ninjatune.net/release/bicep/atlas. Do I add both of them to our digital release https://musicbrainz.org/release/8942fa1f-d847-4... or just one? If one which one?

Do I need to create two distinct releases and disambiguate them based on the format?

no

I was thinking, would it be OK to put two release events with the two cat. numbers in this case?

simukis_: It depends a bit on your preferences, there isn't yet an established standard for how to treat such the-same-but-technically-different releases.

Some people will create individual releases e.g. for every digital vendor, whereas others collapse them all into one (IMO tracking formats and vendors doesn't make much sense for a database like this)

Your specific case is complicated by the different catalog numbers, I don't know if there is any precedent for something like this

I'd probably add both catalog numbers by using the release label twice

got it, that's what I was leaning towards myself as well.

On a certain album (a compilation), the artist credits were wrong for certain recordings, so I selected the proper recording with the right artist. However, I think this might have been the wrong thing to do in hindsight - should I cancel the edit, update the artist, and then merge the recordings afterward instead?

Here is the edit in question: https://musicbrainz.org/release/2d4eece5-f532-4...
