在python中实时播放原始音频文件
作者:互联网
我在python中有一台udp服务器,该服务器不断以原始格式(字节数组)接收来自客户端的语音数据包.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?
解决方法:
PyAudio的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.
