The suite (MP3 Toolkit is a collection of modules) is easy to use--for the most part. There are small oddities, such as not being able to select multiple items with the shift key. Instead you select folders from within the folder. Not unheard of, but against the normal Windows convention. My only major complaint is the lack of batch editing in the tag editor. It can be extremely handy to grab a bunch of files to specify their genre all at once. MP3 Toolkit doesn't allow this.

MP3 Toolkit converted every file I threw at it with one exception--Windows Lossless, a relatively rare bird. It did, however, convert Apple Lossless, Flac, APE, TwinVQ (an even rarer bird), and wave files up to 24-bits/96Hz, as well as all the more common types such as MP3 and WMA. The merger tool worked well, as did the cutting tool, though it wasn't initially obvious that the material between the markers I set was being saved, not cut.

Small oddities aside, MP3 Toolkit works as advertised. It's free, it's effective, what more need I say? Perhaps that if you'd like all your tools under one roof, and are worth a look as well.
