REAPER is a powerful but sensible Windows application designed for the recording, arrangement, editing, mixing and rendering of audio. REAPER provides a flexible but easy to use interface that is equally suited to amateurs and professionals alike.

Some key benefits of REAPER are:
  • Extremely small footprint (full featured, with an installer that is approximately 1MB)
  • Easy to start using: simply drag and drop one of many kinds of files in to edit existing material, or insert a track and arm it for recording. No complex project or definitions to set up.
  • Fast and powerful editing facilities: split, resize, fade/crossfade, pitch shift, timestretch, copy/paste and loop media items with ease. Ripple editing is available, too.
  • Unrivaled routing capabilities: send tracks to any number of other tracks or hardware outputs, with lots of options (pre-fx, post-fx, independent faders, mono or stereo). Not interested in advanced routing? You don't have to use it (and it certainly won't get in the way.)
  • Powerful recording options (supports pre-fx, post-fx recording, can record mixed output of multiple tracks, etc), supports switching record inputs/modes on the fly, input monitoring options (including tape-style auto input monitoring mode), supports auto-punch-in/punch-out, and more. If you want. Otherwise, it just behaves as you would expect.
  • Support for MIDI files, recording MIDI, and VSTi/DXi softsynths. MIDI can be integrated and mixed with audio.
  • User arrangeable user interface with color themes: make REAPER look how you want it to look, and arrange (or hide) elements of the user interface to suit your needs.
  • Support for consolidating track edits and rendering track stems, to enable easy export for other applications.
  • Includes many Jesusonic effects, and supports many plug-ins (including VST and DX plug-ins) with full plug-in delay compensation.

REAPER versions 0.4-0.99 are freeware, but starting with version 1.0 the license will change to very reasonably priced (with amateur and professional rates/support) uncrippled nag-free shareware, supporting unexpiring full functionality in unregistered form.
