使用pyaudio播放无损音乐(wav)

安装pyaudio

sudo apt-get install python-pyaudio python3-pyaudio
pip3 install pyaudio

执行第二步可能会遇到如下错误：

根据网址的指导：

pip will download the PyAudio source and build it for your system. Be sure to install the portaudio library development package (portaudio19-dev) and the python development package (python-all-dev) beforehand.

需要安装portaudio19-dev和python-all-dev：

sudo apt-get install portaudio19-dev python-all-dev python3-all-dev

 

使用pyaudio播放wav音乐：

import pyaudio
import wave
import sys

CHUNK = 1024

if len(sys.argv) < 2:
    print("Play a wave file.\n\nUsage: %s filename.wav" % sys.argv[0])
    sys.exit(-1)

wf = wave.open(sys.argv[1], 'rb')

p = pyaudio.PyAudio()
stream = p.open(format=p.get_format_from_width(wf.getsampwidth()),
                channels=wf.getnchannels(),
                rate=wf.getframerate(),
                output=True)

data = wf.readframes(CHUNK)

while data != '':
    stream.write(data)
    data = wf.readframes(CHUNK)

stream.stop_stream()
stream.close()
p.terminate()
