制作实时聊天平台SoundDevice问题

Question

我要做一个聊天平台，两个人可以在其中进行实时语音聊天。（比如skype）。问题是如何让sounddevice模块始终监听和录音？看看下面的代码，我从这个问题的答案中得到：Play and record sound using pyaudio simultaneously

import sounddevice as sd
import numpy as np
import scipy.io.wavfile as wav

fs=44100


duration = 10  # seconds 
# (I don't want it for 10 seconds, I want it to record as long as the user doesn't close the session)


myrecording = sd.rec(duration * fs, samplerate=fs, channels=2, dtype='float64')
print "Recording Audio for %s seconds" %(duration)
sd.wait()
print "Audio recording complete"

Answer 1

只有事先知道所需的持续时间，才能使用sd.rec()

如果要录制未知时间，则必须使用Stream（或InputStream）API
