在Python中录制麦克风音频

import pyaudio
import wave

# 定义参数
CHUNK = 1024  # 每次读取的音频数据大小
FORMAT = pyaudio.paInt16  # 音频格式
CHANNELS = 1  # 声道数
RATE = 44100  # 采样率
RECORD_SECONDS = 5  # 录音时长
WAVE_OUTPUT_FILENAME = "output.wav"  # 输出文件名

# 初始化PyAudio
audio = pyaudio.PyAudio()

# 打开音频流
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("录音完成.")

# 停止音频流
stream.stop_stream()
stream.close()
audio.terminate()

# 保存录音数据为WAV文件
wf = wave.open(WAVE_OUTPUT_FILENAME, 'wb')
wf.setnchannels(CHANNELS)
wf.setsampwidth(audio.get_sample_size(FORMAT))
wf.setframerate(RATE)
wf.writeframes(b''.join(frames))
wf.close()

print("音频已保存为：{}".format(WAVE_OUTPUT_FILENAME))

pip install pyaudio
