import wave
import pyaudio

定義數(shù)據(jù)流塊

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

錄音時(shí)間

RECORD_SECONDS = 5

要寫入的文件名

WAVE_OUTPUT_FILENAME = “output.wav”

創(chuàng)建PyAudio對(duì)象

p = pyaudio.PyAudio()

打開數(shù)據(jù)流

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

print("* recording")

開始錄音

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

停止數(shù)據(jù)流

stream.stop_stream()
stream.close()

關(guān)閉PyAudio

p.terminate()

寫入錄音文件

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()
