Python调用电脑麦克风录音

import wave import pyaudio

定义数据流块

CHUNK = 1024 FORMAT = pyaudio.paInt16 CHANNELS = 2 RATE = 44100

录音时间

RECORD_SECONDS = 5

要写入的文件名

WAVE_OUTPUT_FILENAME = “output.wav”

创建PyAudio对象

p = pyaudio.PyAudio()

打开数据流

stream = p.open(format=FORMAT, channels=CHANNELS, rate=RATE, input=True, frames_per_buffer=CHUNK) print("* recording")

开始录音

frames = [] for i in range(0, int(RATE / CHUNK * RECORD_SECONDS)): data = stream.read(CHUNK) frames.append(data) print("* done recording")

停止数据流

stream.stop_stream() stream.close()

关闭PyAudio

p.terminate()

写入录音文件

wf = wave.open(WAVE_OUTPUT_FILENAME, ‘wb’) wf.setnchannels(CHANNELS) wf.setsampwidth(p.get_sample_size(FORMAT)) wf.setframerate(RATE) wf.writeframes(b’’.join(frames)) wf.close()
