'''REAPER''' (an [[acronym]] for ''Rapid Environment for Audio Production, Engineering, and Recording'') is a [[digital audio workstation]] and MIDI sequencer application created by [[Cockos]]. The current version is available for [[Microsoft Windows]] ([[Windows XP|XP]] and newer) and [[macOS]] ([[Mac OS X v10.5|10.5]] and newer), as well as for [[Linux]].<ref name="extremraym.com">{{cite web|url=https://www.extremraym.com/en/reaper-5-review/|title=REAPER 5: An Exhaustive Review|date=4 November 2015}}</ref><ref name="phoronix.com">{{cite web|url=https://phoronix.com/scan.php?page=news_item&px=Reaper-DAW-For-Linux|title=Reaper Audio Software Is Coming To Linux |publisher=Phoronix}}</ref> REAPER acts as a host to most industry-standard plug-in formats (such as [[Virtual Studio Technology|VST]] and [[Audio Units|AU]]) and can import all commonly used media formats, including video. REAPER and its included plug-ins are available in 32-bit and 64-bit format.

==Licensing==
REAPER provides a free, fully functional 60-day evaluation period. For further use two licenses are available – a commercial and a discounted one. They are identical in features and differ only in price and target audience, with the discount license being offered for private use, schools and small businesses. Any paid license includes the current version with all of its future updates and a free upgrade to the next major version and all of its subsequent updates, when they are released. Any license is valid for all configurations (x64 and x86) and allows for multiple installations, as long as it is being run on one computer at a time.<ref>{{cite web |title=REAPER {{!}} Purchase |url=https://www.reaper.fm/purchase.php |access-date=6 July 2023}}</ref>

==Customization==
Extensive customization opportunities are provided through the use of ReaScript (edit, run and debug scripts within REAPER) and user-created themes and functionality extensions.

ReaScript can be used to create anything from advanced macros to full-featured REAPER extensions. ReaScripts can be written in EEL2 (JSFX script), [[Lua (programming language)|Lua]] and [[Python (programming language)|Python]].<ref>{{Cite web|url=https://www.reaper.fm/sdk/reascript/reascript.php|title=REAPER {{!}} ReaScript|website=reaper.fm|access-date=2017-01-29}}</ref> SWS / S&M is a popular, open-source extension to REAPER, providing workflow enhancements and advanced tempo/groove manipulation functionality.<ref>{{Cite web|url=https://www.sws-extension.org/|title=SWS / S&M Extension|website=www.sws-extension.org|language=en|access-date=2017-01-29}}</ref>

ReaClassical provides a full open source environment for doing classical music editing, including source-destination editing, multitrack track-group editing and a two-lane crossfade editor.<ref>{{cite web |title=Classical Editing Tools for REAPER |url=https://chmaha.github.io/ReaClassical/ |website=chmaha.github.io |access-date=16 December 2022}}</ref>

REAPER's interface can be customized with user-built themes. Each previous version's default theme is included with REAPER and theming allows for complete overhauls of the [[Graphical user interface|GUI]]. REAPER has been translated into multiple languages and downloadable language packs are available. Users as well as developers can create language packs for REAPER.<ref>{{Cite web|url=https://www.reaper.fm/langpack/|title=REAPER {{!}} Language Packs|website=www.reaper.fm|access-date=2017-01-29}}</ref>

==Included software and plug-ins==
REAPER comes with a variety of commonly used [[Audio signal processing|audio production effects]]. They include tools such as ReaEQ, ReaVerb, ReaGate, ReaDelay, ReaPitch and ReaComp. The included Rea-plug-ins are also available as a separate download for users of [[List of audio editing software|other DAWs]], as the ReaPlugs VST FX Suite.<ref>{{Cite web|url=https://www.reaper.fm/reaplugs/|title=REAPER {{!}} ReaPlugs|website=www.reaper.fm|access-date=2017-01-31}}</ref>

Also included are hundreds of [[JSFX]] plug-ins<ref name=":0">{{Cite web|url=https://www.reaper.fm/about.php|title=REAPER {{!}} About|website=www.reaper.fm|access-date=2017-07-24}}</ref> ranging from standard effects to specific applications for MIDI and audio. JSFX scripts are text files, which when loaded into REAPER (exactly like a VST or other plug-in) become full-featured plug-ins ranging from simple audio effects (e.g delay, distortion, compression) to instruments (synths, samplers) and other special purpose tools (drum triggering, surround panning). All JSFX plug-ins are editable in any text editor and thus are fully user customizable.<ref>{{Cite web|url=https://www.reaper.fm/sdk/js/js.php|title=REAPER {{!}} JSFX Programming|website=reaper.fm|access-date=2017-07-24}}</ref>

REAPER includes no [[Third-party software component|third-party software]], but is fully compatible with all versions of the [[Virtual Studio Technology|VST standard]] (currently VST2 and VST3). It can also run [[Audio Units|AU]] plug-ins (on macOS), [[CLever Audio Plug-in|CLAP]] plug-ins, [[DirectX plugin|DX]] plug-ins (on Windows) and [[LV2]] plug-ins,<ref>{{cite web|title=REAPER {{!}} About|url=https://www.reaper.fm/about.php#technical|website=www.reaper.fm|access-date=2022-11-29}}</ref> and thus works with the vast majority of both free and commercial plug-ins available. REAPER x64 can also run 32-bit plug-ins alongside 64-bit processes.<ref name=":0" /> As of version 5.97, REAPER supports [[Audio Random Access|ARA 2]] plugins.<ref>{{Cite web|url=https://rekkerd.org/streamlined-workflow-melodyne-and-reaper-now-communicate-via-ara-2/|title=Streamlined workflow: Melodyne and Reaper now communicate via ARA 2|date=2019-02-22|website=Rekkerd|language=en-US|access-date=2019-02-22}}</ref>

==Video editing==
While not a dedicated video editor, REAPER can be used to cut and trim video files and to edit or replace the audio within. Common video effects such as fades, wipes and cross-fades are available. REAPER aligns video files in a project, as it would an audio track, and the video part of a file can be viewed in separate video window while working on the project.<ref>{{Cite news|url=https://www.extremraym.com/en/reaper-5-review/#Video_Editing|title=REAPER 5: An Exhaustive Review|date=2015-11-04|newspaper=ExtremRaym|access-date=2017-02-06|language=en-US}}</ref>
