问题描述

我正在尝试读取像这样的mp3文件中嵌入的bpm:

i am trying to read bpm embedded in mp3 file like this one :

我尝试使用

Windows.Storage.FileProperties.MusicProperties

，但仅包含标题，歌手等. 它无法读取我之前显示的bpm.

but it only contains title, singer, etc. it can't read the bpm i showed before.

我正在调查 https://taglib.github.io/他们似乎也没有这种功能. 有什么解决方法吗?

im looking into https://taglib.github.io/ they seems not having such function too. is there any workaround to this?

推荐答案

将音乐文件加载到StorageFile后，您需要在代码中进行类似的调用，如下所示:

When you've loaded your music file into a StorageFile, you'll want to place a similar call in your code like this:

var fileProps = await file.Properties.RetrievePropertiesAsync(null);

这将为您提供所有显示为Dictionary<string, object>的系统属性的列表.

This will get you a list of all the system properties exposed as a Dictionary<string, object>.

然后您可以按以下方式获取BPM值:

You can then get the BPM value as follows:

if (fileProps.ContainsKey("System.Music.BeatsPerMinute"))
{
    var bpmObj = fileProps["System.Music.BeatsPerMinute"];
    if (bpmObj != null)
    {
        var bpm = bpmObj.ToString();
    }
}

您可以在此处找到可用文件属性的完整列表:
