With a plethora of portable music players around and the different type of audio file formats they each play, you're bound to have to convert your tracks every now and then. Switch has the advantage of being free and allowing you to quickly batch convert audio tracks. We were impressed by the number of output formats, more than a dozen, with all the common file types like mp3, wma or aac available. You'll also be able to set the bitrate, once again choosing from more than a dozen options and more importantly with a choice of variable or constant bitrate. Switch also features an error protection feature to enhance your recordings. The toolbox feature is supposed to help you perform any audio task, but all it really does is automatically install extra software from the developer. We suggest using it only if you know precisely what you want to do and are ready to install a new application. Switch also has a feature to add CD album details from the freeDB database. Even though we tried it on a few well known tracks, it didn't really work. Despite these drawbacks, Switch is a speedy audio converter with many features.
