Question

我要求bucket=audio_summary获得在热情方面排名很高的歌曲。前100首hotttessst歌曲都返回track.status: 'complete'但音频摘要始终是空对象。

如何获取time_signature和tempo等音频摘要数据？没有track.status: complete暗示这些信息应该包含在回复中吗？

      "track": {

        "audio_summary": {}

    }
  }

Answer 1

看起来你有这首歌的SongId而不是TrackId。如果您在查询中将'track'替换为'song'，您将获得预期的结果。

此： https://developer.echonest.com/api/v4/song/profile?api_key= *****************＆安培;格式= JSON和ID = SOMVZDS14DDE5909E7＆安培;斗= audio_summary

返回：

{  
   "response":{  
      "status":{  
         "version":"4.2",
         "code":0,
         "message":"Success"
      },
      "songs":[  
         {  
            "artist_id":"ARYUDWF12F2B89BB33",
            "artist_name":"The Weeknd",
            "id":"SOMVZDS14DDE5909E7",
            "audio_summary":{

               "speechiness":0.042317,
               "acousticness":0.124391,
               "instrumentalness":0.0,
               "mode":0,
               "time_signature":4,
               "duration":216.46667,
               "loudness":-5.528,
               "audio_md5":"",
               "valence":0.586261,
               "danceability":0.713659
            },
            "title":"Can't Feel My Face"
         }
      ]
   }
}

我能够追踪到这一点的唯一原因是，将任何ID投入到跟踪API中会返回您看到的存根响应，并且我能够使用spotify id获取此歌曲的audio_summary，所以我知道它是可用。

Echonest跟踪配置文件请求始终返回空的audio_summary
