用过Vista的朋友都知道，Vista的音量控制十分强大，可以单独给每个应用程序设置不同的音量大小。
这个功能十分方便，比如有些朋友喜欢边听歌边上网，可是有些网页是有声音的，如果单独把浏览器静音，就不会受到影响了。
显然，为了这个功能安装去Vista，似乎不太现实，要是机子硬件不够强大就更装不了Vista了。那么能不能在XP下实现这个功能呢？
IndieVolume是一款Windows音频系统的扩展工具，能在XP、2000和2003下实现上述功能。
由于我用Vista，虚拟机装的2003无声卡，所以只能简单介绍一下了。
启动后会自动进入托盘，点开后会出现上面的界面。
所有运行了的程序都会出现在上面，选择你要单独控制的程序在“Handled”上面打勾即可。
还可以设置不同的FX效果，包括很多种预设的效果，在菜单里面可以更改这些效果。
原理应该是插入一个线程到应用程序的进程中进行控制，官方要求必须安装了DirectX 8或DirectX 9才行。
国内网站找到的大多都是v2版本，而目前最新版本是v3了，使用上稍微有点不用，末尾的下载中提供了两个版本。
英文的，本想汉化一下，可是资源有点多，最近快开学有点忙，实在抽不出时间来弄这个，就先欠着吧。
IndieVolume is a supplement to Windows Volume Control that dramatically improves the way Windows applications sound.
IndieVolume is for experienced Windows users dreaming about those handy features Windows Volume Control is lacking for years - per-application volume, per-application balance and mute, support of FX, support of multiple audio devices. IndieVolume has all that functionality. With IndieVolume you get the most out of your audio.
IndieVolume allows every application have separate volume level, independent of other applications volume level. For example, you are listening to the music, and suddenly some application LOUDLY shouts or dings. With IndieVolume you just configure shouting application to sound at different (lower) volume compared with the volume at which player application is playing music.
IndieVolume also supports per-application balance and mute. For example, you have occasionally visited one of that websites, that play horrible sounds in the background. Using IndieVolume you can just mute web browser not to output any sound at all. Or you like to play flash games and would like to control volume level. IndieVolume can do that as well.
IndieVolume is extremely useful for VoIP applications. When application marked as "exclusive" plays a sound, IndieVolume automatically mutes all other applications. For example, you are having business chat in Skype or GoogleTalk, and suddenly some application plays a sound. With IndieVolume, you can mark Skype/GoogleTalk as "exclusive", so none application would sound during your Skype/GoogleTalk calls.
IndieVolume allows per-application selection of playback device. For example, if you have built-in sound card and SoundBlaster as second sound card, or USB/Bluetooth headset, you can configure certain applications play on built-in sound card, and others play on SoundBlaster or USB headset, fully employing your audio hardware.
IndieVolume supports per-application FX audio effects. If you do not have SoundBlaster, you can enrich application sounds by applying fancy FX effects, likewise I3DL2 Reverb, Waves Reverb, Chorus, Compressor, Distortion, Flanger, Gargle, etc. IndieVolume comes preconfigured with over 50 FX presets, similar to SoundBlaster ones -- IndieVolume can be treated as software replacement for SoundBlaster.
Finally, unique functionality of IndieVolume, coupled with great programming and great support we offer, make IndieVolume number 1 Windows enhacement you should have.
压缩包里面的是绿色版，其中v2已经处理过了，可以直接使用。v3的话提供一组有用的信息给大家，要低调哦，不明白的话私下问我就好了。
