如何用Python写一个捕获到声卡声音超过一定阈值，则自动按键的脚本

Question

老弟最近初学Python，网上搜了半天，没合适的攻略，只好请教各位老哥了

Answer 1

import sounddevice as sd
import keyboard

# 设置阈值和按键
threshold = 0.1  # 设置声音阈值
key_to_press = 'space'  # 设置要按下的按键

# 定义回调函数
def audio_callback(indata, frames, time, status):
    volume_norm = np.linalg.norm(indata) * 10  # 计算音量的标准化值
    if volume_norm > threshold:
        keyboard.press(key_to_press)  # 按下按键

# 打开声音输入流
stream = sd.InputStream(callback=audio_callback)
stream.start()

# 持续监听声音输入
while True:
    pass

# 停止声音输入流
stream.stop()
