This is REAPER.
REAPER is a complete digital audio production application for computers, offering a full multitrack audio and MIDI recording, editing, processing, mixing and mastering toolset.
REAPER supports a vast range of hardware, digital formats and plugins, and can be comprehensively extended, scripted and modified.
Do Anything

REAPER's full, flexible feature set and renowned stability have found a home wherever digital audio is used: commercial and home studios, broadcast, location recording, education, science and research, sound design, game development, and more.

From mission-critical professional environments to students' laptops, there is a single version of REAPER, fully featured with no artificial limitations. You can evaluate REAPER in full for 60 days. A REAPER license is affordably priced and DRM-free.

Constant Evolution

A new REAPER 6 license includes unlimited free updates through REAPER version 7.99. Frequency varies, but updates are typically released every few weeks.

These updates include bug fixes, feature improvements, and significant new features, all of which are free. Updates only take a minute or so. All preferences and configurations are preserved, and forward and backward compatibility are maintained.
