HighLife VST features some impressive features like a built in WAV editor, auto mapping and some unique effects processing.
Input formats include WAV and MP3 and it can export into various formats including SFZ.
Probably the most impressive feature is the one that lets you load another VST inside of HighLife and sample it! Say you own a copy of Reaktor Synth and you make a really cool patch. You might want to collab with someone that doesn't own Reaktor. HighLife can load Reaktor and load your patch and make a preset out of it. Now your collaborator only needs to download the patch and HighLife and he can use the same patch as you!
