这只是一个Demo

开始

• 将音频数据分析的结果存储到数据库
  

#!/usr/bin/python  
# -*- coding: utf-8 -*-  
from dejavu import Dejavu  
  
config = {  
    "database": {  
        "host": "127.0.0.1",  
        "user": "root",  
        "passwd": "passw0rd",  
        "db": "dejavu",  
    },  
    "database_type": "mysql",  
}  
  
# 将数据提取到Mysql （音乐的指纹）  
  
djv = Dejavu(config)  
  
djv.fingerprint_directory("/Users/zhangjianxin/home/mp3/", [".mp3"])  
print(djv.db.get_num_fingerprints())  
  

• 监听麦克风进行识别歌曲
  

#!/usr/bin/python  
# -*- coding: utf-8 -*-  
  
  
from dejavu import Dejavu  
from dejavu.recognize import FileRecognizer, MicrophoneRecognizer  
  
config = {  
    "database": {  
        "host": "127.0.0.1",  
        "user": "root",  
        "passwd": "passw0rd",  
        "db": "dejavu",  
    },  
    "database_type": "mysql"  
}  
djv = Dejavu(config)  
  
# 识别从mic输入的音频 只获得5秒的音频  
secs = 5  
song = djv.recognize(MicrophoneRecognizer, seconds=secs)  
if song is None:  
    print "No Match"  
else:  
    print(song)  

需要用到的工具

python 2.7  
  
brew install portaudio  
brew install ffmpeg  
brew install mysql-connector-c # my_config.h  
brew install mysql  
#!!!  mysql-connector-c (my_config.h) ->  mysql  
ln -s  ../../../../mysql-connector-c/6.1.11/include/my_config.h ./  
  
  
brew link mysql # create links  
  
pip install mysql-python  
pip install numpy==1.10.2 # 版本兼容性问题  
pip install PyDejavu
