python实现录音功能（可随时停止录音）

本文实例为大家分享了python实现录音功能的具体代码，供大家参考，具体内容如下

# -*- coding: utf-8 -*-
import pyaudio
import time
import threading
import wave
class Recorder():
 def __init__(self, chunk=1024, channels=1, rate=64000):
   self.CHUNK = chunk
   self.FORMAT = pyaudio.paInt16
   self.CHANNELS = channels
   self.RATE = rate
   self._running = True
   self._frames = []
 def start(self):
   threading._start_new_thread(self.__recording, ())
 def __recording(self):
   self._running = True
   self._frames = []
   p = pyaudio.PyAudio()
   stream = p.open(format=self.FORMAT,
           channels=self.CHANNELS,
           rate=self.RATE,
           input=True,
           frames_per_buffer=self.CHUNK)
   while(self._running):
     data = stream.read(self.CHUNK)
     self._frames.append(data)
stream.stop_stream()
   stream.close()
   p.terminate()
def stop(self):
   self._running = False
def save(self, filename):
p = pyaudio.PyAudio()
   if not filename.endswith(".wav"):
     filename = filename + ".wav"
   wf = wave.open(filename, 'wb')
   wf.setnchannels(self.CHANNELS)
   wf.setsampwidth(p.get_sample_size(self.FORMAT))
   wf.setframerate(self.RATE)
   wf.writeframes(b''.join(self._frames))
   wf.close()
   print("Saved")
if __name__ == "__main__":
for i in range(1,4):
   a = int(input('请输入相应数字开始:'))
   if a == 1:      
     rec = Recorder()
     begin = time.time()
     print("Start recording")
     rec.start()
     b = int(input('请输入相应数字停止:'))
     if b == 2:
       print("Stop recording")
       rec.stop()
       fina = time.time()
       t = fina - begin
       print('录音时间为％ds'％t)
       rec.save("1_％d.wav"％i)

本人在尝试语音识别领域的研究，欢迎一起探讨。
