Spotify acquires audio detection startup Sonalytic

Spotify bought echonest and shut down their api, resulting in the demise of this awesome website: http://labs.echonest.com/Uploader/index.html

Infinite Jukebox Downloader (Python)

It seems to work fine for me? I just searched for Nothing Else Matters by Metallica and am listening to it on endless mode.

According to their Reddit, it's going to ggo offline in the next week or two.

On October 1 [2016], you will no longer be able to upload new tracks to the Infinite Jukebox

What exactly is that doing? Is it analysing the song and trying to make a "perfect loop"?

The visualization is known as a chord diagram[1][2], and these particular ones generated by Echo Nest show repetitions in the analyzed songs (e.g. chorus lines). A circle is a good starting visualization because there is a linear progression from beginning to end (single path) and the chord diagram lends itself well to the metrics Echo Nest is demonstrating.

Pretty awesome.. really track dependent though. 'Veridis Quo - Daft Punk', 'Come to Daddy - Aphex Twin' and 'Building Steam With A Grain Of Salt - DJ Shadow' all give pretty great results but something like 'Trigger - In Flames' is.. mediocre at best.

Darude - Sandstorm has to be the craziest: http://labs.echonest.com/Uploader/index.html?trid=TRXMGLP14A...

I think it might ruin most classical, and at the very least kill the vibes on most jazz.

Their FAQ: http://labs.echonest.com/Uploader/faq.html

It basically keeps the song going by jumping around to different parts that match within the song. It can lead to interesting effects (different extended solos, jumping around between choruses). It keeps the song going forever.

To start click at the top of the circle after selecting a song.

I don't understand - what does/did it do?

You can upload a song, and it will jump through the song backwards and forwards such that the song will seamlessly continue forever.

(Can't upload a new song anymore as of October, but you can search for previously uploaded songs.)

Didn't spotify take on $1 billion in convertible debt last year?

What's happened with that? From what I remember it was under not so good conditions for spotify.

How does this differ from the echo nest that they acquired?

The Music Ally article on the acquisition is also a good read: http://musically.com/2017/03/07/spotify-buys-startup-sonalyt....

The patent on the technology is a solid read: https://patentscope.wipo.int/search/en/detail.jsf;jsessionid...

@anonu the jsessionid param was giving me some issues.

Here's an alternate that should work:

Just out of curiosity, is there a similar technology for "shazaming" video footage?

I've wondered similar but, for Youtube at least, there doesn't seem to be a frame-level API. You can pull a video and analyze it yourself, but you'd basically need to download all of youtube.

you could record/analyse and recreate a concert using the album/single releases
