win11在语音通话时，麦克风音量经常被自动下调，导致我听不清对面s|b声音，所以我一气之下。。。气了一下

1. 获取麦克风音量

from ctypes import cast, POINTER
from comtypes import CLSCTX_ALL
from pycaw.pycaw import AudioUtilities, IAudioEndpointVolume

# 获取麦克风设备
devices = AudioUtilities.GetMicrophone()

# 激活音量控制接口
interface = my_mic.Activate(IAudioEndpointVolume._iid_, CLSCTX_ALL, None)

# 获取音量控制指针
volume = cast(interface, POINTER(IAudioEndpointVolume))

# 获取当前音量
current_volume = volume.GetMasterVolumeLevel()

# 获取音量范围
min_volume, max_volume, _ = volume.GetVolumeRange()

# 调整麦克风音量
volume.SetMasterVolumeLevel(vol, None)

2. 持续检测并调整

from ctypes import cast, POINTER
from comtypes import CLSCTX_ALL
from pycaw.pycaw import AudioUtilities, IAudioEndpointVolume
import datetime
import time

mic = AudioUtilities.GetMicrophone()
interface = mic.Activate(IAudioEndpointVolume._iid_, CLSCTX_ALL, None)
volume = cast(interface, POINTER(IAudioEndpointVolume))

while True:
    v_v = volume.GetMasterVolumeLevel()
    #print('MIC音量值为', v_v)

    if v_v < target:
        volume.SetMasterVolumeLevel(target, None)
        hour = datetime.datetime.now().hour
        minute = datetime.datetime.now().minute
        print(f'{hour}:{minute} 麦克风音量调至{target}')

    time.sleep(sleep)

3. 添加配置文件便于调整

from ctypes import cast, POINTER
from comtypes import CLSCTX_ALL
from pycaw.pycaw import AudioUtilities, IAudioEndpointVolume
import json
import os

mic = AudioUtilities.GetMicrophone()
interface = mic.Activate(IAudioEndpointVolume._iid_, CLSCTX_ALL, None)
volume = cast(interface, POINTER(IAudioEndpointVolume))

# 检查config.json结构是否错误
try:
    with open('config.json', 'r',encoding='utf-8') as f:
        config = json.load(f)
    target = config['target']
    sleep = config['sleep']
    volume.SetMasterVolumeLevel(target, None)
except:
    if os.path.exists('config.json'):
        os.remove('config.json')
        print('配置文件config.json错误，已删除')

# 生成配置文件
if not os.path.exists('config.json'):
    min_volume, max_volume, _ = volume.GetVolumeRange()
    print('麦克风音量范围:', min_volume, max_volume)

    with open('config.json', 'w',encoding='utf-8') as f:
        json.dump({'target': max_volume, '//target': f'{min_volume}~{max_volume}', 'sleep': 0.5}, f, indent=4)
    print('已生成配置文件config.json')
    target = max_volume
    sleep = 0.5

4. 完整代码

from ctypes import cast, POINTER
from comtypes import CLSCTX_ALL
from pycaw.pycaw import AudioUtilities, IAudioEndpointVolume
import datetime
import time
import json
import os


while True:
    try:
        mic = AudioUtilities.GetMicrophone()
        interface = mic.Activate(IAudioEndpointVolume._iid_, CLSCTX_ALL, None)
        volume = cast(interface, POINTER(IAudioEndpointVolume))
        break
    except:
        time.sleep(10)
        continue


try:
    with open('config.json', 'r',encoding='utf-8') as f:
        config = json.load(f)
    target = config['target']
    sleep = config['sleep']
    volume.SetMasterVolumeLevel(target, None)
except:
    if os.path.exists('config.json'):
        os.remove('config.json')
        print('配置文件config.json错误，已删除')

if not os.path.exists('config.json'):
    min_volume, max_volume, _ = volume.GetVolumeRange()
    print('麦克风音量范围:', min_volume, max_volume)

    with open('config.json', 'w',encoding='utf-8') as f:
        json.dump({'target': max_volume, '//target': f'{min_volume}~{max_volume}', 'sleep': 0.5}, f, indent=4)
    print('已生成配置文件config.json')
    target = max_volume
    sleep = 0.5




print('开始监听...')

while True:
    # 获取当前音量值
    v_v = volume.GetMasterVolumeLevel()
    #print('MIC音量值为', v_v)

    if v_v < target:
        volume.SetMasterVolumeLevel(target, None)
        hour = datetime.datetime.now().hour
        minute = datetime.datetime.now().minute
        print(f'{hour}:{minute} 麦克风音量调至{target}')

    time.sleep(sleep)

5. pyinstaller打包

cd /d <path>
pyinstaller --onefile mic.py

得到mic.exe

6. 编写脚本

启动脚本mic.bat：

@echo off
if "%1" == "h" goto begin
mshta vbscript:createobject("wscript.shell").run("""%~nx0"" h",0)(window.close)&&exit
:begin

mic.exe

关闭cmd窗口后台运行

关闭脚本kill.bat：

taskkill /IM mic.exe /F
pause

7. 把启动脚本加入系统启动项

windows+R

shell:startup

把mic.bat的快捷方式放入startup文件夹，实现开机自动静默启动
