使用pyaudio录制麦克风

import pyaudio
import wave

# 设置音频参数
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 44100
CHUNK = 1024
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "output.wav"

# 创建音频流对象
p = pyaudio.PyAudio()

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

print("开始录制...")

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("录制完成.")

# 停止录制并关闭音频流
stream.stop_stream()
stream.close()
p.terminate()

# 保存录制的音频数据到文件
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()

print("音频文件保存成功：", WAVE_OUTPUT_FILENAME)
