Absolutely essential for moving sounds around in iOS from app to app. Ive tried Audiocopy, and it was buggy, a lot of crashing. This works perfectly, especially in conjunction with Dropbox. It is very easy to record from apps directly into AudioShare, build a loop library in Dropbox, and import into Loopy, Auria, iMPC, your DAW etc. Making a drum loop in Gadget? Run a drum hit through a delay or reverb app in Audiobus, record into AudioShare, trim, and import back into Bilbao as a sample. Very quick, functional and reliable app to work with. Only problem is sometimes selecting trim points in loops, but you can use the nudge button to get it right. Somebody else reviewed this app by saying you dont even know how much you need it until you start using it, and I couldnt agree more, it is in every aspect of my workflow now, and I wasnt even sure what I would use it for when I bought it.
