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 pyaudioimport timeimport threadingimport 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。
