基于pyaudio利用Python編程實(shí)現(xiàn)播放音頻mp3、wav等格式文件

輸出結(jié)果

實(shí)現(xiàn)代碼

T1、while循環(huán)輸出數(shù)據(jù)流的方法

def play():
    chunk=1024  #2014kb
    wf=wave.open(r"16k.wav",'rb')
    p=PyAudio()
    stream=p.open(format=p.get_format_from_width(wf.getsampwidth()),channels=wf.getnchannels(),rate=wf.getframerate(),output=True)

    data = wf.readframes(chunk)  # 讀取數(shù)據(jù)
    print(data)
    while data != '':  # 播放  
        stream.write(data)
        data = wf.readframes(chunk)
        print('while循環(huán)中！')
        print(data)
    stream.stop_stream()   # 停止數(shù)據(jù)流
    stream.close()
    p.terminate()  # 關(guān)閉 PyAudio
    print('play函數(shù)結(jié)束！')

T2、while循環(huán)輸出+if判斷數(shù)據(jù)流的方法

def play():
    chunk=1024  #2014kb
    wf=wave.open(r"16k.wav",'rb')
    p=PyAudio()
    stream=p.open(format=p.get_format_from_width(wf.getsampwidth()),channels=wf.getnchannels(),rate=wf.getframerate(),output=True)

    data = wf.readframes(chunk)  # 讀取數(shù)據(jù)
        
    while True:
        data=wf.readframes(chunk)
        if data=="":
            break
        stream.write(data)
    stream.stop_stream()   # 停止數(shù)據(jù)流
    stream.close()
    p.terminate()  # 關(guān)閉 PyAudio
    print('play函數(shù)結(jié)束！')

if __name__ == '__main__':
    audio_file='16k.wav'  #指定錄音文件
    play()                #播放錄音文件
