在Python中访问计算机麦克风最简单的方法是什么？

import pyaudio
import wave

# 定义参数
CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 44100
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "output.wav"

# 初始化PyAudio
audio = pyaudio.PyAudio()

# 打开麦克风进行录音
stream = audio.open(format=FORMAT,
                    channels=CHANNELS,
                    rate=RATE,
                    input=True,
                    frames_per_buffer=CHUNK)

print("开始录音...")

frames = []

# 录制音频数据
for i in range(0, int(RATE / CHUNK * RECORD_SECONDS)):
    data = stream.read(CHUNK)
    frames.append(data)

print("录音结束.")

# 停止录音并关闭流
stream.stop_stream()
stream.close()
audio.terminate()

# 保存录制的音频数据到WAV文件
wave_file = wave.open(WAVE_OUTPUT_FILENAME, 'wb')
wave_file.setnchannels(CHANNELS)
wave_file.setsampwidth(audio.get_sample_size(FORMAT))
wave_file.setframerate(RATE)
wave_file.writeframes(b''.join(frames))
wave_file.close()
