The main reason is that: APE audio file employs a symmetric algorithm, meaning the decoding takes comparable resources to encoding, which makes it unsuitable for all but the fastest portable players (via Rockbox firmware). Another reason is that: it has limited support on software platforms other than Windows; on other platforms only decoding is officially supported by third-party programs. Although the original source code is freely available, the license is not considered to be an open source one. Congratulations. I have been looking a long time for a good and powerful mp3-tagging tool. There are lots of tools out there which have great looking user interfaces and great design, but are ly useless. I have been testing your mp3tag-software since one week. and I really like it! It is a bit more technical than other tools but these technical things offer lots of flexibility! That's exactly the tool I was looking for. I will buy a licence in a few minutes. Just wanted to send you some feedback. BTW: I like the "lifetime licence" idea!
