groovyでechonestを叩いてみる

http://echonest.com/ではネットと音楽のおもろそうな試みがいくつかされています。

そのうち「似ているアーティスト検索」、「サンプル音源やヴィデオの検索」、音源ファイルのBPM解析などはJavaライブラリが提供されているので、APIキー取得して、お試ししてみた。

//echonest
import com.echonest.api.v3.artist.*
import com.echonest.api.v3.EchoNestException

def API_KEY = "<YOUR_API_KEY>"
def artistName = "animal collective"
ArtistAPI artistAPI

//Artist Similarity
try{
  artistAPI = new ArtistAPI(API_KEY)
  def artists = artistAPI.searchArtist(artistName, false)
  artists.each{a->
    println "Artist: "+a.name
    
    def similars = artistAPI.getSimilarArtists(a,0,10)
    println "- similar artists -"
    similars.each{s->
      println s.item.name
    }
    println "---"
  }
}
catch(EchoNestException e){
  println e
}

//Get Audio Sample
artistAPI = new ArtistAPI(API_KEY)
def artists = artistAPI.searchArtist(artistName,false)
artists.each{a->
  def audioList = artistAPI.getAudio(a,0,10)
  audioList.getDocuments().each{audio->
    println "Artist: "+audio.artistName
    println "Title: "+audio.title
    println "Date: "+audio.date //java.util.Date
    println "Release: "+audio.release
    println "Length: "+audio.length //float
    println "Link: "+audio.link
    println "URL: "+audio.url
    println "---"
  }
}

結果はこんなかんじ。
