Question

是否有免费的Soundbooth替代方案，可以在Flash音轨中添加提示点？我似乎记得你可以将它们添加到文件本身（我想）。我知道你可以用FLV做到这一点。

在我买SB之前检查..

Answer 1

必须有一些免费的应用程序，但你想要做的事情有点简单。我只是为你准备了一个简单的'app'。我说app，它实际上是一个允许执行以下操作的swf：

加载MP3文件
擦洗它
添加/删除/拖动标记
导出这些标记的FLV提示点

以下是您使用它的方式：

双击舞台加载mp3
点击并拖动进行擦洗 - 黑线将显示为“播放头”
ALT +点击添加标记，然后可以拖动
Shift +单击以删除标记
Shift +双击以获取剪贴板中的提示点。声音将停止播放作为确认。

您可以调整swf的大小以获得更大的擦洗区域。

这是我现在最基本的方法，不是很花哨，不是很干净，但它应该做的工作。此外，您可以根据需要扩展它，调整xml / output / etc.

您需要做的就是抓住FlexibleFactory's audiofx Library，我用来从FileReference加载MP3并编译代码：

    import org.audiofx.mp3.MP3FileReferenceLoader;
    import org.audiofx.mp3.MP3SoundEvent;

    import flash.events.Event;
    import flash.events.MouseEvent;
    import flash.geom.Rectangle;
    import flash.media.Sound;
    import flash.media.SoundChannel;
    import flash.net.FileFilter;
    import flash.net.FileReference;
    import flash.system.System;

你只能将提示点嵌入到flv文件而不是mp3中。

我也注意到闪光灯本身无法正确读取这些点！确保在购买之前测试它

SoundBooth的免费替代品，可将提示点添加到MP3 for Flash中吗？
