Echonest returns empty when trying to identify a song

[Roy Ten Cate]

Hi there,

I've been trying out Echoprint and I managed to create a fingerprint code based on a test MP3 file (Adele Someone Like You (assuming that he will recognize it)) and it returns an empty result.

Copy paste:

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

This was recorded from a speaker with a phone. I used the audio editor "Audacity" to convert and export my m4a file to a MP3 file.

However, when I download the actual song and use the first 20 seconds edited and exported with Audacity, it returns to me with the correct information. So based on this evidence, I'm going to assume that there is no problem with the actual query. I tried both POST with console and GET with my browser. I have tweaked with different parameters I found on the API documentation. This means I have also specified a version, many even.

Here is the URL:

If anyone could help me resolve this issue... You will be a life saver and I'll be in your debt forever.

Roy,

The Echoprint code you posted doesn't decode properly. "Inflated FP times (146) and codes (147) are different lengths." This might indicate a problem with your Codegen application. Can you post the code string for the downloaded file you made?

Hello David,

I believe you mean this one? I created a new code with the audio file's full length.

These code strings are ENMFP (see the version 3.15 in the JSON file), not Echoprint.

ENMFP is not going to work for matching over-the-air recordings.

To use Echoprint you need to build the Codegen for your platform. Please see http://echoprint.me for more information.

Hello David,

Sorry my bad... I thought that didn't matter.

I managed to build the codegen of Echoprint for Windows. After another attempt with the same file I got the same empty result.

Here's my code string:

Just an idea, but could FFmpeg be to blame? I don't know this for sure, but I installed the 64 bit version (my OS) from http://ffmpeg.zeranoe.com/builds/ , and followed the instructions on http://www.wikihow.com/Install-FFmpeg-on-Windows

Roy,

This Echoprint string doesn't have enough codes in common with any one track to match anything confidently.

David,

What do you suggest I should do then? Because I've followed the instructions for Echoprint on Windows. 

The audio file is a snippet from a downloaded live concert. The sound is clear but it's not the CD version, so I assume this is a perfect file for testing. I have also tried with other songs using a microphone.

A concert recording will not match anything unless that same concert was published as a live album. Even then, an over-the-air recording will not be as accurate as file-based matching.

Echoprint does not identify songs from their melody and structure, it identifies recordings from their acoustic details. A different performance of the same song will usually not match the original.
