python - 在python中实时播放原始音频文件

Question

我在python中有一台udp服务器，该服务器连续接收来自客户端的原始格式(字节数组)的语音数据包。如何在服务器端实时播放声音？有推荐的库或方法吗？

如果需要，这是我非常简单的服务器代码(我对此表示怀疑)

import socket

UDP_IP = "192.168.1.105"
UDP_PORT = 5005

sock = socket.socket(socket.AF_INET, # Internet
                     socket.SOCK_DGRAM) # UDP
sock.bind((UDP_IP, UDP_PORT))

while True:
    data, addr = sock.recvfrom(1024) # buffer size is 1024 bytes
    #what to do to stream the incoming voice packets?

PyAudio https://people.csail.mit.edu/hubert/pyaudio/

import pyaudio

p = pyaudio.PyAudio()

stream = p.open(format=pyaudio.paFloat32,
                channels=1,
                rate=44100,
                output=True)

data, addr = sock.recvfrom(1024) # buffer size is 1024 bytes

while data != '':
    stream.write(data)
    data, addr = sock.recvfrom(1024) # buffer size is 1024 bytes

stream.stop_stream()
stream.close()

p.terminate()

有一种使用回调方法的方法可能会更好。
