Reaper 4.7

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. REAPER works with almost any hardware and can be used in combination with a vast universe of other software and plug-ins. Take advantage of REAPER's full functionality using only your current computer and a microphone, or use REAPER to drive an entire professional recording studio.

REAPER features:

• Record audio and MIDI from multiple inputs simultaneously
• Layer recorded tracks and takes over previous recordings
• Edit recordings in almost any imaginable way
• Hundreds of audio and MIDI processing effects included, or choose from thousands of third-party effects
• All editing and effects are completely non-destructive

• MMCSS option for improved Windows 7/8 audio device performance
