REAPER (Rapid Environment for Audio Production, Engineering and Recording) is a powerful but sensible Mac app that lets you record, edit, render and arrange multi-track waveform audio.

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 professionals and amateurs alike.

Here are some key features of "REAPER":

Easy to use:
· Equally usable by hobby users and professionals alike. 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 settings or definitions are required.

Extremely small footprint:
· REAPER is full featured, but its installer is barely over 1 megabyte. It starts and closes
· fast, and is easily installed on new systems or on portable drives.

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.

Wide open compatibility:
· Sane, human readable, human editable project file format. Support for reading and writing many common file formats. Support for consolidating track edits and rendering track stems, to enable easy export for other applications. EDL import/export for Samplitude and Vegas.

MIDI support:
· Support for MIDI files, recording MIDI, and VSTi/DXi softsynths. MIDI can be integrated and mixed with audio.

Customizeable user interface:
· 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.

Bundled Effects and 3rd party plug-in Support:
· Includes built in effects including a compressor, gate, FFT EQ, and some basic synthesizers, and includes many Jesusonic effects, and supports many plug-ins (including VST and DX plug-ins) with full plug-in delay compensation.

Requirements:

· Minimum system: 500mhz processor, 128MB RAM, 10MB free disk space, 800x600 in 256 colors or higher
· Recommended system: Multiple processors, 1GB RAM, >1GB free disk space, 1280x1024 in 16.7M colors

Limitations:

· 30 days trial period.
