Mr_Monkey: I'm working on cleaning up promise chains and converting things to use async/await and ES6 promises rather then bluebird promises at the moment

And at the same time moving some data stuff over to bb-data-js

Hopefully reducing the complexity of fetching data and improving error checking

Eventually I can start migrating the new data access finding to use TypeScript and TypeORM but that's some way down the line - the refactoring is more important

hey so whats the difference between submitting acoutizids through picard and using an extractor programme on acoustizbrainz, arent they the same?

Jaykin: AcoustId and AcousticBrainz are two totally different things

AcoustId deals with audio fingerprinting, which means it can generate a digital "fingerprint" from one of your audio files and look it up in its database

That allows you to identify the music based on the audio only

is the acoust id like an mbid

the musicbrainz identifier

AcousticBrainz deals with extracting certain characteristics from the audio

Depends how you look at it. What both have in common is that they are an identifier you can use to look up e.g. specific recording

But the difference is how they are assigned: AcoustId is based on calculations of the audio itself

The MBID is an arbitrarily assigned identifier. Just something saying: There is a recording, and we give it this unique ID

also AcoustId and MBID for a recording are not a 1 to 1 match. many recordings have multiple AcoustIds, and an AcoustId can have multiple recordings on MB.

That clears out some confusions i had. Using picard and i encountered this

what does it mean

cant submit acoutids, unless its already there?

Not sure what the question really is, but this is the release data from MusicBrainz for a release callef "Lost" with 4 tracks

The checkmark in front indicates that you have a file matched to this track, and that you have saved it. hopefully you checked the file really is for this track before saving ;)

The golden disc indicates that this release is considered "complete", which means you have files for all 4 tracks

This is also shown by the 4/4

You can't submit AcoustIds if they are already there

what does it mean hah, i should have been more specific

ah so theres an acoustids

If you got this result with the "Scan" button this actually means the AcoustIds where already there, and you can't submit them

ok so if there is an acoutids, does that mean there is an musicbrainz entry for it, or the two are separate?

they are in general separate, there are many AcoustIds without MB recording (Picard cannot submit those, but other tools can)

sorry for that

ahh i see. So acoutids are only obtained when someone submits them, are they gotten from other sources?

But if you get a result in Picard this currently always means there is a MBID, Picard cannot give back results from only AcoustId

Yes, that's bascially true. The AcoustIds first need to be submitted by someone, because they need the audio data analyzed. And linked properly to MB for Picard to use it

now for the MBID, lets say the MBID thing is still in editorial review, can picard still register it?

the MB webservice does not return pending changes, so no, Picard can't see those

oh...

the only exeption I think are cover art images from CAA, you can get unapproved ones

but so many changes are auto-edits nowadays :D

I'm lookin through picard, so composer in one of the file, what is composer? Whats the difference with artist?

compose is the one who wrote the music

the artist usually is who performed the music

hello

in picard, scan vs lookup. Lookup puts all the files on the right and gives green ticks, scan does nothing, bottom of the programme it says it looks for fingerprints but nothing happens.

Jaykin_: Have a look if it generated a AcoustId, should be in the tag list at the bottom

also have a look if there is some error in Help > View Error/Debug log

hi, i wanted to join metabrainz for the google code in, is there someone i can talk to for that?

Skye: Hi and welcome. You can probably just ask here. For details Freso is our community manager and also admin for the Code In

Otherwise just grab a task at https://codein.withgoogle.com/tasks/?sp-organiz... :D But you can always ask questions here if unsure

thanks for the info :)

i will probably need sone help with docker. i dont have a lot of experience using it

yeah i read through it

Skye: which task are you looking at?

mo''in'

one sec, still scrolling through them

Skye: depending what you want to do or how familar you already are with MusicBrainz or some related projects there are also some editing tasks that could be a way to get into the project

i am mostly looking for python related and some beginner docker tasks, tho i am fine with editing

But if you want to take up a programming task please do. the mentors of the task and others here can for sure help you setup the tools

alright, thanks :)

Picard is written in Python and doesn’t use docker at all.

ooh, i will check that out

Yep, good point. The "Add tests for MusicBrainz Picard code" would be a good start

We'll hopefully have a few more Picard development tasks up in a few days

that was the first one that caught my eye too, and the upgrading messybrainz one

Most of other Python projects are servers and may require basic docker setup, see https://github.com/metabrainz?language=python

but the setup has instructions avalaible and its not too long generally, so its not too hard

Yep :)

for the add tests thing, i have to just grab any 3 functions and add tests to make sure they work properly right?

right, just check with mentors if no one else is already testing it beforehand

Yes, exactly. Just let us know what the functions are before you start
