Python 3.7.0

1.pyaudio的安裝

直接用pip安裝的pyaudio不支持3.7，所以在安裝或import的時(shí)候會(huì)報(bào)錯(cuò)。所以直接下載whl文件安裝即可。

whl下載地址：https://github.com/intxcc/pyaudio_portaudio/releases

切換到whl文件目錄，直接用pip安裝

pip install PyAudio-0.2.11-cp37-cp37m-win_amd64.whl

2.pyaudio 播放音頻代碼示例

#引入庫  

import pyaudio  
import wave  
import sys  

#定義數(shù)據(jù)流塊  

chunk =1024  
#只讀方式打開wav文件  
f = wave.open(r"D:\1.wav","rb")  
p = pyaudio.PyAudio()  

#打開數(shù)據(jù)流  

stream = p.open(format = p.get_format_from_width(f.getsampwidth()),  

                channels = f.getnchannels(),  

                rate = f.getframerate(),  

output =True)  

#讀取數(shù)據(jù)  

data = f.readframes(chunk)  

#播放  

while data != b"":  

    stream.write(data)  

    data = f.readframes(chunk)  

#停止數(shù)據(jù)流  

stream.stop_stream()  

stream.close()  

#關(guān)閉 PyAudio  

p.terminate()
