REAPER is a digital audio workstation. It is 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. It is suitable for recording anything from a soloist to a band to an orchestra.

REAPER converts your computer into the full power of any top-of-the-line recording studio. It will almost any existing audio interface. Even interfaces manufactured by companies whose software does not allow you to use any other hardware interface.

REAPER doesn’t have track types, busses, tools, or offline processing. If you want to create a drum bus, simply add a track above the drum tracks and press the folder button. The drums will automatically send to the folder. Once you get the drum levels and FX tweaked right where you want them, you can record the folder’s output to non-destructively freeze the drums and move on.
