在javaFx中，对于类似卡拉OK的应用程序，我应该如何使用音频突出显示文本
我正在构建一个JavaFx应用程序，其中我有一个文本文件和一个音频mp3文件，可以读取它。当我使用对象播放音频并显示文本文件中的文本时。有没有办法在播放每个单词时突出显示它们？我知道字幕是如何编码的，并保存在一个单独的文件中，但在这里它必须为每个单词做。i、 e.文本文件中的每个单词都应该有元数据，即它应该保持高亮显示的时间与mp3文件开头的偏移量 另一种方法是使用公式计算文本和音频文件的长度，并找到每个世界应保持高亮显示的大致时间，但此cam使高亮显示不同步在javaFx中，对于类似卡拉OK的应用程序，我应该如何使用音频突出显示文本,java,audio,sync,javafx,javafx-2,Java,Audio,Sync,Javafx,Javafx 2,我正在构建一个JavaFx应用程序，其中我有一个文本文件和一个音频mp3文件，可以读取它。当我使用对象播放音频并显示文本文件中的文本时。有没有办法在播放每个单词时突出显示它们？我知道字幕是如何编码的，并保存在一个单独的文件中，但在这里它必须为每个单词做。i、 e.文本文件中的每个单词都应该有元数据，即它应该保持高亮显示的时间与mp3文件开头的偏移量 另一种方法是使用公式计算文本和音频文件的长度，并找到每个世界应保持高亮显示的大致时间，但此cam使高亮显示不同步 是否有任何标准方式或标准元数据格式
是否有任何标准方式或标准元数据格式可以对信息进行编码，在旁白音频播放时，一个单词应该突出显示多长时间 我对此使用了直接逻辑。这些东西不可能是自动的，但需要无休止的努力，所以首先你需要让用户设置时间。显示.txt文件，并在后台播放歌曲。借助于此，用户高亮显示单词，现在您可以借助System.Current time（以毫秒为单位）获得计时，并将计时存储在数组或列表中。完成后，现在你开始唱卡拉OK。根据计时，突出显示文字。按ESC键，文字将突出显示。根据需要更改.txt文件。 请忽略我糟糕的编码风格：p 下面是Swing中的一个演示：

我认为这与JavaFX无关。我在其他应用程序中看到的一种方法是，当一个单词开始时，首先点击空格。然后您可以存储此信息。@user510083是的，这是关于Tecnique的一般问题。我希望javaFx中有更简单的方法/api。你能解释一下你认为我应该存储哪些信息吗？每个单词开头的时间戳？要么如此，要么只是一个ms列表+一个单独的单词列表，两者都应该有相同的元素编号；。通过这种方式，单词列表可以是一个文本文件，看起来像来自网络的歌词。。文本文件中的一行是在卡拉OK模式下显示的一行。你还在工作吗？请回答，我也在做同样的事情，几乎完成了@乔伊·罗汉嘿，谢谢你的评论！我在我的V1版本中确定了这一点，但如果我能在v2中做到这一点就太好了。你能分享一下你是如何做到这一点的吗？我不认为这与JavaFX有关。我在其他应用程序中看到的一种方法是，当一个单词开始时，首先点击空格。然后您可以存储此信息。@user510083是的，这是关于Tecnique的一般问题。我希望javaFx中有更简单的方法/api。你能解释一下你认为我应该存储哪些信息吗？每个单词开头的时间戳？要么如此，要么只是一个ms列表+一个单独的单词列表，两者都应该有相同的元素编号；。通过这种方式，单词列表可以是一个文本文件，看起来像来自网络的歌词。。文本文件中的一行是在卡拉OK模式下显示的一行。你还在工作吗？请回答，我也在做同样的事情，几乎完成了@乔伊·罗汉嘿，谢谢你的评论！我在我的V1版本中确定了这一点，但如果我能在v2中做到这一点就太好了。你能分享一下你是如何做到这一点的吗？
