This program can then be called from Picard. This avoids GPL problems, while still allowing excellent integration. I might worry about the performance issues of creating a new process to identify each track, but if it's taking several minutes then who cares about the process overhead.

If I analyze some MP3s, they are first copied to the "ungrouped files" section. Pressing the "analyse" button, lot of them are copied to the "album" section, but some stay again in the "ungrouped file" section. If I put them manually to the "album" section using drag & drop, I finally get the opportunity to use the "send tagged information" button. The status bar says "sending PUID information", but why, if it is said not to be possible to generate PUIDs with Picards built-in analyzer? Furthermore: I used the same MP3s some days ago with beta 1. Then, the files had a very bad recognition value (<10 percent, although the album was in the MB-db). Then, I used the "send tagged information to MB" button. Today with beta 2, all songs are said to have a 100% recognition, although still some of them stay in the "ungrouped file" section. It would be great if someone could clarify this as I want to write an article on MP3 tagging and would really like to understand this open source idea of fingerprint-supported tagging. I still have problems to understand the meaning of the button “send tagged information to MB”.

Bravo. And at further risk of sounding like a kiss-ass: Thank you, to all the devs who are working so hard on this project. I’m about sick of the spoiled brat whiners too. Bravo.

The genpuid program will be closed source. I'm working on it right now, in fact. Once I get the basic functionality working, I'll be looking for feedback on making sure it covers everybody's needs as best as possible (without taking up a lot of dev time on my side). We'll probably be doing most of the discussion on the MusicDNS portion of the MusicIP forums. Max: Yep, I’m one of the MusicIP developers. The genpuid program will be closed source.

At the top we just said there wasn't going to be an open source PUID generator, now you say you're writing genpuid. Is this contradictory, or is genpuid going to be closed source? I assume therefore that you have either signed an NDA or work for musicip? Being closed source is no biggie as far as I'm concerned (other than potential support / longevity issues). After all, until someone puts in the (no doubt considerable) time to come up with a better solution, it's by far the best we've got (seems much better than TRM to me), and one has little sympathy with all those people shouting at you to write something for them for free...

If a PUID is available, then it will be returned. Currently, new PUID's are only generated when using MusicIP Mixer. I'm working on a "genpuid" program which can be used to generate and submit the appropriate info to create a puid. This will mean you can either use MusicIP Mixer, or genpuid to put new puid's into the system. We should be back into a 24 hour cycle by the end of today, and we'll be working hard to (A) guarantee that minimum turnaround and (B) shorten it where possible.

So Picard can generate a fingerprint. Does it then query MusicDNS for a PUID whose deep analysis is consistent with the fingerprint (given user-specified closeness parameters) - or does it algorithmically generate a 'candidate PUID' from the fingerprint and then ask MusicDNS to match it to a reference PUID which was created from the deep analysis? Or neither of the above? In either case, it seems like anyone who wants to support MB by creating ids that others can use for identification will always be required to use the MusicIPMixer - that is what you're saying, right?

I do have some questions about the difference, though. Is the idea that with the fingerprint data generated by libofa, you can only do a "lookup" on the MusicDNS web-service, which may (or may not) return a PUID if a sufficiently close match has already been submitted via the closed-source MusicIP Mixer? When the submission process "works" (in the fullness of time) how will you get the PUID to submit? Will it be taken from the tags written by the MusicIP Mixer? At any rate, thanks for the helpful clarification that allowed me to at least pose these questions, which I think I know the answers to. @alex Well, it’s helpful to understand that there’s a difference between fingerprinting and analysis.
