REAPER is a digital audio workstation: a complete multitrack audio and MIDI recording, editing, processing, mixing, and mastering environment.
Using your current computer and no other software, you can import any audio and MIDI, synthesize, sample, compose, arrange, edit, mix, and master songs or any other audio projects.
If you add a hardware audio interface of your choice (AD/DA: analog-to-digital/digital-to-analog) and a microphone, you have a complete recording studio, suitable for recording anything from a soloist to a band to an orchestra (even if the orchestra is just you).
Nondestructive multi-track recording means that you can record and layer take after take, correcting, editing, revisiting, and tweaking to your heart’s content.
There are inexpensive audio interfaces designed just to plug guitars in to, and there are very fancy audio interfaces designed to convert many simultaneous line and microphone inputs.
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, even interfaces manufactured by companies whose software does not allow you to use any other hardware interface.
The evaluation version of REAPER is complete and uncrippled. There are no artificial interruptions or restrictions, and you can save and load projects normally. We believe in giving you a fair chance to make sure that REAPER works correctly with your hardware and suits your workflow.
The REAPER installer simply copies REAPER and its support files to disk. It does not install anything except itself.
If after 30 days you decide that REAPER is not for you, simply delete it.
