通信交互 socket套接字 音频传输

服务端：

#音频文件传输
import socket,wave
hostname = socket.gethostname()
port = 8888
#开始
# 基本架构
s = socket.socket()
s.bind((hostname,port))
s.listen()

content = a.recv(921600)
with open('text.wav','wb') as f:
    f.write(content)

#基本架构

s.connect((hostname,port))

with wave.open('output.wav') as f:

    framerate = f.getframerate()
    #读取全部帧
    frames = f.readframes(nframes)
    print(nframes,framerate)
    #以数组形式保存
    framerates = np.frombuffer(frames,dtype='short')
    s.sendall(framerates)
s.close()
