Awesome stuff. We are working on something that will benefit both parties (us and you guys) immensely. Is there a way to contact you? No info on your HN profile

  if it's echoprint related, write echoprint@echonest.com -- otherwise contact@echonest.com (i'm brian@echonest.com but i doubt you want to write just me)

Where do we go and ask questions for setting up a mirror for us (VLC/VideoLAN)? Is there an IRC channel?
- brianwhitman 15y ago
  there's a google group-- that's probably the easiest for now. you can pester alastairp on the musicbrainz IRC channel too (he's our resident musicbrainz/EN liaison)

What's the relationship (if any) or distinction between Echoprint and Chromaprint/Acoustid? http://acoustid.org/ http://acoustid.org/
- brianwhitman 15y ago
  No relationship. Obviously the intent is the same. Distinction: we handle small pieces of audio from anywhere in the song (20s), ours works "over the air" via microphone, we have a huge database via our content partners.

About your data dumps: you're about to get hammered, so please share them in torrent! This would be much better for the thousands of people wanting to bootstrap. Also, I understand json is very easy to use, etc. But those big dumps cry for a binary format. Or at least add zlib/lzma compression so people don't waste bandwidth on uuencoded binary data in json.
- brianwhitman 15y ago
  the dumps are in a format that other code understands (fastingest.py) The code data is compressed using zlib (and then base64'd.) It's all on s3-- in our experience, big data dumps like this get relatively little traffic after the original hype dies down and a torrent doesn't make sense. We're pretty sure amazon can handle the load :)

    S3 has bittorrent support built in, it's trivial to enable. But you probably knew that.

I'm curious about the hashing algorithm. I read about the planned whitepaper, but some preliminary info would be cool (e.g refs to academic papers that you build on).
- brianwhitman 15y ago
  it is similar to our closed source FP ENMFP, which you can read about here: http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.185.699 http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.185.... The codegen is very different (instead of relying on echo nest chroma, it does its own onset detection) but the back end side is almost the same.
