Hi, are there any downloadable applications for iPhone who are sound editing programs? I'm going to use it when I transcribe music, and I want it to work like the program "Transcribe!" to PC, perhaps, or like Cool Edit Pro, Wavelab, Adobe Audition etc. I want to able to scroll in the music and be able to start from the place I've put the marker when I press play. A slow down function would be very nice too of course. Thanks!
