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)
