REAPER converts your computer into the full power of any top-of-the-line recording studio.
Minus, of course, a room full of shockingly expensive converters, microphones, amplifiers, and, well, talent.
If you are a top-of-the-line recording studio interested in REAPER, this part of the discussion has probably insulted your intelligence.
So we`ll just say that unlike some other DAWs, REAPER will support almost any existing audio interface.
