转换为 Windows mpeg4 后如何访问 Samsung Voice Recorder m4a 书签？

Question

我用 Samsung Voice Recorder 录制了几个文件，并为每个文件插入了几个书签。在我的 phone 上，它们是 m4a 文件。当复制到我的电脑上时，它们显示为 mpeg4 文件。

我需要将这些添加到 Powerpoint（每张幻灯片一个文件），并使用书签来触发动画（最好使用 vba），但是书签没有显示。

任何人都可以帮助或指出正确的方向吗？提前致谢。

这是其中一个文件的 link。此文件有 6 个书签，时间如下：00:00、00:03、00:04、00:05、00:12、00:24。 https://1drv.ms/u/s!AkCe6_YwGEfWgupe2wsCcerSf4nFUw

我已经添加了最终代码。音频文件遵循针对特定客户有细微变化的脚本，因此剪辑都非常接近相同。我将音频文件添加到每张幻灯片，然后从原始音频复制书签并将它们应用到新文件。谢谢！！

您可以使用 VBA 为视频或音频添加书签。

例如，假设您选择了音频或视频：

With ActiveWindow.Selection.ShapeRange(1)
   With .MediaFormat.MediaBookmarks
      ' Add a bookmark at the 5 second mark
      .Add 5000, "My bookmark name"
   End With ' MediaBookmarks
End With  ' Selected Shape
