Is there a free alternative to Soundbooth for adding cue-points to audio tracks for use in Flash? I seem to remember that you can add them to the file itself (I think). I know you can do this with FLV.
Just checking before I buy SB..
There must be some free app out there, but what you're trying to do is somewhat simple. I just whipped together a simple 'app' for you. I say app, it's actually a swf which allows to do the following:
Here's how you use it:
You can resize the swf for a larger scrub area.
This is the most basic approach I could come with right now, not very fancy, not very clean, but it should do the job. Also, you can extend this as you like, adjust the xml/output/etc.
All you need to do is grab FlexibleFactory's audiofx Library, which I use to load an MP3 from FileReference and compile the code bellow:
package {
import org.audiofx.mp3.MP3FileReferenceLoader;
import org.audiofx.mp3.MP3SoundEvent;
import flash.display.Sprite;
import flash.display.StageAlign;
import flash.display.StageScaleMode;
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;
