Hi,

I've created an ActionScript 3 version of the Echo Nest track API.

It includes all the API methods, including upload (which requires Flash 10).

The code is here: http://github.com/also/echo-nest-flash-api/

API documentation: http://static.ryanberdeen.com/projects/echo-nest-flash-api/asdoc/index.html

An example:

var trackApi:TrackApi = new TrackApi();
trackApi.apiKey = 'EJ1B4BFNYQOC56SGF';

trackApi.getMode({id: 'music://id.echonest.com/~/TR/TRLFPPE11C3F10749F'}, {
  onResponse: function(mode:Array):void {
    trace('Mode: ' + mode[0] +', confidence: ' + mode[1]);  // Mode: 1, confidence: 1
  }
});

Uploading (both chooseFile() and uploadFile() must happen in response to user clicks):

var fileReference:FileReference;

private function chooseFile():void {
  fileReference = new FileReference();
  fileReference.addEventListener(Event.SELECT, function(e:Event):void {
    fileReference.addEventListener(Event.COMPLETE, function(e:Event):void {
      // file loaded, call uploadFile next
      trace('loaded ' + fileReference.name);
    });
    fileReference.load();
  });
  fileReference.browse();
}

private function uploadFile():void {
  trackApi.uploadFileData(fileReference.data, {
    onResponse: function(track:Object):void {
      trace('id: ' + track.id + ', md5: ' + track.md5);  // id: music://id.echonest.com/~/TR/TRMVA0211BC6E08329, md5: 2f45abacba9e9d2312afa63a8df10d23
    },
    onEchoNestError: function(error:EchoNestError):void {
      trace(error.code + ': ' + error.description);
    }
  });
}

I hope this is useful; let me know if you use it! I'll be adding the artist API soon.

Strange, I can't access the documentation. It gives me some XML error response and says access denied.

I've just moved the documentation to http://also.github.com/echo-nest-flash-api/asdoc/.

hi also, I am trying to upload using your library, but is seems that your "uploadFileData" that you put in the example in your post does not exist. And in the TrackApi.as you mention it in the comments: "@see #uploadFileData()", but in also in your documentation there is no public or private function with this name.

Am i not getting it? I hope you can help me, because i am a novice user, but very eager!

hi also, i got it to work, because i used the example code that was at http://github.com/also/echo-nest-flash-api/. i included it for other forum visitors:

var fileReference:FileReference;

private function chooseFile():void { fileReference = new FileReference(); fileReference.addEventListener(Event.SELECT, function(e:Event):void { uploadFile(); }); fileReference.browse(); }

private function uploadFile():void { trackApi.uploadFileReference({file: fileReference}, { onResponse: function(track:Object):void { trace('id: ' + track.id + ', md5: ' + track.md5);}, onEchoNestError: function(error:EchoNestError):void { trace(error.code + ': ' + error.description); } }); }

But thanks for you work, it works although i find it sometimes hard to read/understand how e.g. your void within a void within a void is build up.
