I found a tuto with the streaming way to performe cover song identification.
I also add a way to download some sound with youtube dl.
to download musique now just type:
youtube-dl --config-location config_youtube-dl
I juste run the exemple with somme mp3 that i found.
Now i was juste too lasy to make a script that download the mp3.
Next time I'll do it, promise!
I had also to run the exemple in stream mode.
lot of nice thing to do :)
