The major features of this software are the Windows Media Player control API, which allows you to control the players, format them and search for folders and streams, the Windows Movie Control API, which controls most of Winamp's features and allows you to control your digital audio and video files using Windows Movie maker, the Winamp plug-in API, which allows you to use external hardware devices to play your files, control your digital audio and video effects, create sub-files and transfer them to a hard drive, and the Winamp XML transport API, which allows you to transfer Winamp samples and other Winamp information to other applications. As far as sub-pictures and the like are concerned, you can easily insert them into your Windows movie without having to modify or lose your original file. In fact, the Winamp plug-in will even save your original file so that you do not have to worry about that. This Winamp XP has advanced features like the advanced graphics and image editing facilities, the Vorbix compression technology, the HD output support, the Windows masking technology, the chroma keying, and also the video recording and editing features. It also provides the Microsoft Groove Music plug-in, which allows you to play back your music files in digital audio format (alsa, vorq, wma, etc.) on your Winamp machine.
The Winamp plug-in version 1.5.3 provides great improvements over its previous versions. With this Winamp plug-in version 1.5.3, you are able to control your audio visual effects with a lot more precision and ease than ever before. You can now make use of your favorite digital audio workstation, your favorite Winamp machine, and even go hands-free with your computer as you mix and view your audio tracks with this Winamp plug-in. The best part here is that the audio conversion quality has been significantly enhanced with the use of the latest encoding technologies such as x compressors, lossless compression algorithms, and new buffer systems such as those used in net stereo. This means that Winamp output will be higher quality and the music will sound better.
