REAPER can run on nearly any modern computer, is easy to install and fast to get running. Use whatever audio device you have available, from cheap onboard audio all the way up to professional audio interfaces.

Record audio and MIDI, trivially edit and overdub.

Use pitch shifting, pitch correction, and time stretching for maximum creative potential.

Easily reorder or duplicate regions of projects, allows easy restructuring of songs.

Convenient: record in the basement studio, edit on your laptop later, quickly render mixes to share with other musicians.

Tons of included FX, supports widely available free and commercial VST, AU, and DirectX plug-ins.

Perfectly at home in a studio, REAPER will use as much hardware as you can throw at it. With no practical limits on hardware I/O, MIDI devices, control surfaces, track counts, or plug-in delay compensation, REAPER is a modern and technologically advanced platform for recording and mixing.

Although REAPER is digital and modern, it supports classic analog features such as varispeed playback and recording, enabling legendary production techniques that are often forgotten.

Fantastic editing tools including tab to transient, takes and comps, time stretching/pitch shifting, pitch envelopes.

REAPER is an open platform that can freely use almost any VST, AU, or DirectX plug-in, or integrate as a ReWire master or slave, with another DAW.

A wonderful environment for broadcast editing, REAPER supports many features broadcast users have come to expect.

Ripple editing (sometimes known as "shuffle mode") allows you to edit content and have later content automatically adjusted.

Use the playrate control to play your project at different rates, great for skimming through speech or other contents at higher speed.

Edit on the fly while recording: record audio in one project tab, and (while recording) import/edit that same recording audio in a second project tab.

Plug-in effects can be applied to individual sections of timeline audio.

When finished with editing, REAPER can bounce/render projects as fast as possible (usually faster than realtime).

REAPER's recording capabilities are second to none, and it is routinely used for location recording by world class radio networks.

Record any number and any combination of inputs (mono, stereo, multichannel, or MIDI) with no practical limit on recording length.

Add tracks or change recording inputs, all on the fly even while recording.

For redundancy or performance, REAPER supports recording to multiple disks simultaneously.

Support for writing compressed files on the fly, large files, or gaplessly switching to new files at configurable intervals, for very long recording sessions.
