写在前面 最近在电脑上跟人聊天时发现它不能像手机那样自动录音,找了一圈也没发现类似的软件。于是作为小白的我,在 AI 的帮助下完成了这个工具。如果你也有类似需求,希望这款微信通话自动录音器能帮到你。
软件简介
微信通话自动录音器 是一款支持 Windows 平台的桌面小工具,主要功能包括:

  • 自动检测微信的通话窗口(支持语音 / 视频通话)
  • 一旦检测到通话,自动开始录音,通话结束自动保存 mp3 文件
  • 支持选择麦克风或虚拟声卡(推荐安装 VB-Audio Virtual Cable,可完整捕获 \"你和对方\" 的声音)
  • 支持自定义录音保存路径

使用步骤

  • 下载并解压本程序(建议放在英文路径下)
  • 安装 FFmpeg(用于录音处理,详见下文)
  • 安装虚拟声卡(推荐 VB-Audio Virtual Cable)
  • 设置系统“侦听”功能(详见下文)
  • 双击运行程序,选择输入设备与保存路径
  • 最小化后可在系统托盘中运行,程序将自动录音

虚拟声卡安装方法

  • 打开官网:[url=]https://vb-audio.com/Cable/[/url]
  • 点击 Download 下载压缩包(如 VBCABLE_Driver_Pack43.zip)
  • 解压后,右键以管理员身份运行 VBCABLE_Setup_x64.exe
  • 点击 Install Driver 并按提示完成安装,重启电脑后生效

系统“侦听”功能设置(非常重要)

  • 右键任务栏右下角喇叭图标 → 选择“声音设置”
  • 点击右侧“更多声音设置” → 切换到“录制”标签页
  • 找到要录音的设备(例如:“麦克风”、“CABLE Output” 等),右键 → 选择“属性”
  • 切换到“侦听”标签页 → 勾选“侦听此设备”
  • 播放设备选择你常用的扬声器或耳机(建议不要选虚拟声卡)
  • 点击“应用” → “确定”
  • [Python]  纯文本查看  复制代码?

    最后
    这个工具比较小众,但希望它能帮到你。如果你也有自己的“小需求”,不妨动手试试。哪怕不全懂,有 AI 帮助,一切都变得简单了起来。

    本工具纯属个人学习作品,尚未支持多线程录音、静音检测等高级功能,请酌情使用。如遇问题,欢迎理性反馈或共同改进。
