- the presence of a lossy mode(could wavpack be split in two "editions" instead of having its entire features in one codec?)
- lack of native tags(you will agree that its easier to manipulate tags with metaflac in flac files, and it's a bit tricky in wavpack not using an external app)
- hardware support(I've noticed that the hardware support list in the wavpack site hasn't got any addition since a long time ago, could the implementation of wavpack on hardware find some kind of hinderance because of the whole hybrid mode thing, or is it just because hardware dealers don't care, as they don't care with anybody else... what could it be done to wavpack get more attention as flac has got)PS: I like both codecs, but it's just frustrating neither of them going really mainstream in hardware.
Recently I tested PowerAMP on my Sumsung android phone and it plays wavpack lossy -hh mode flawless + gapless. CPU @ %25 vs 18% for mp3. http://powerampapp.com/Also :http://neutronmp.com/
The 1MB limitation is discussed at some length in this thread..Foobar2000 handles APEv2 tags itself (without the WavPack library) and obviously it does not implement the arbitrary 1MB limit that I decided on for the WavPack library (although I guess that there is probably some other, higher, limit). This means that any tags over 1MB will be ignored by the WavPack library and will not show up when using the WavPack command-line tools or any program that uses the WavPack library for reading tags (Winamp comes to mind). Of course, they will continue to work fine in Foobar2000.
