How to use partial fingerprints

[elboul...@gmail.com]

Hi Lukas !

I'm getting started with Chromaprint. I managed to computer fingerprints on an audio file with `fpcalc`, send an HTTP request to the AcousticID server, and got awesome results ! That is ok.

Now, I'd like to use that on an audio stream. I read your last blog entry here <https://oxygene.sk/2016/12/chromaprint-1-4-released/>, and could easily compute partial fingerprints on a stream. My question now is: how should I use that ? Should I send it to the server with a lookup query, and give the chunk size for the duration ? Am I supposed to send a new request every 10 seconds (assuming 10 secs is the chunk size) ?

Ideally I'd like to add audio fingerprint support to Goodvibes: <https://github.com/elboulangero/goodvibes/issues/18>

Thanks for your feeback !

This kind of partial matching is not supported by AcoustID and most
likely never will be. Hosting of the free AcoustID service would get
too expensive if I started supporting it. It was added to Chromaprint
to be used outside of AcoustID.

Hi, thanks for your reply.

Hmm, so if I compute these partial fingerprints on a stream, what can I do with it ?

Being a radio player, I'm only interested in looking up fingerprints, not submitting them.
If I understand you properly, I should query another web service than AcousticID, right ?
Does such a service already exist, or there is nothing done yet ?

On the client side, you can't do much with the partial fingerprints.

Support for this was added to Chromaprint to allow people to build
their own backends. I'm currently working on a service that will do
real-time stream identification, but that will not be freely available
(most likely still open source though) and it will only work on
private content.

Ok, thanks for the clarification, this stuff is not for me then :)
Good luck with your projects !

Hi Lukas,

Do you have some (good) news about to use Chromaprint with AcoustID for "Real-Time stream identification" ?

Thanks for your help

Best Regards,

Chris

I really appreciated if you give me some suggestion how to build the own backend using Chromaprint for real-time stream identification. Thanks

You can use or study how this works - https://github.com/acoustid/acoustid-priv

If you don't want to implement the backend and just want real-time stream identification, contact me at lu...@acoustid.biz. I can provide you access a service with this API:

Hi Lukas,

Thanks a lot, I will take a look at those information and will contact you later.

I think I have a similar issue. I have clips that are 5 to 10 seconds, and that likely contain ( part of, considering their length ) songs that are in the database.

Other services will match the short clips to songs ( but I can't afford them ), but AcoustId won't. I don't need perfect matches, just a most probable solution for humans to later review.

Any idea what I could do to get this to work? I can run my own server, code things, do some heavy lifting, I'm just looking for *some* kind of path to being able to build something that does the job.

Thanks for any idea anyone would have.
