使用python语言录制声音

import pyaudio
import wave

# 设置参数
chunk = 1024  # 每次读取的音频数据大小
format = pyaudio.paInt16  # 音频数据的格式
channels = 1  # 声道数
rate = 44100  # 采样率
record_seconds = 5  # 录制时长
output_filename = "output.wav"  # 输出文件名

# 创建PyAudio对象
audio = pyaudio.PyAudio()

# 打开音频流
stream = audio.open(format=format,
                    channels=channels,
                    rate=rate,
                    input=True,
                    frames_per_buffer=chunk)

print("开始录制声音...")

frames = []  # 存储录制的音频数据

# 录制声音
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()
audio.terminate()

# 保存录制的音频数据为WAV文件
wave_file = wave.open(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()

print("音频文件保存成功，文件名为：" + output_filename)
