As this link say: http://echoprint.me/post/20475922191/updates-to-echoprint-song-identify-api It has been fixed a bug that should improve matching accuracy and cut down on the number of “no results” false negatives whereby the server was erroneously returning a response of the following form:

{"response": {"status": {"version": "4.2", "code": 0, "message": "Success"}, "songs": []}

But I'm still having problem with any .mp3 that I Upload. I get always this kind of response.

On the contrary, using the fingerprinting of ENMFP, it works properly.

Suggestions?

Radosky,

Can you please check that you have include a parameter of the form "&version=4.12" in your Echoprint query? This is what identifies the query as an Echoprint one as opposed to an ENMFP one.

Thanks,

Andrew

Oh god, yesss with"&version=4.12" it works! Thank very much!

Look at this:

Using the form that you gave me: "&version=4.12" I get a completely wrong response:

Without the version at the end I get a Correct response:

Do you have an idea why works like this?

I just want to mention that this is the only song with Echoprint code that worked out without using the "&version=4.12" at the and of the query, all the other trial gave me only the classic Response {"response": {"status": {"version": "4.2", "code": 0, "message": "Success"}, "songs": []} Thank you once again.

Firstly, let's check that you are associating the different codegens with the version appropriately:

ENMFP codegen => "&version=3.15" in the query (or you can equivalently leave it out altogether)

Echoprint codegen => "&version=4.12" in the query (not optional)

ENMFP and Echoprint are completely different fingerprinting systems; their fingperprints are not interchangeable in any way whatsoever.

For more information about this sort of thing please check out the Echoprint FAQ.

Andrew
