'''Audacity'''是一款[[跨平台]]的音频编辑软件，用於錄音和編輯音訊，是[[自由軟體|自由]]、[[開放原始碼]]的軟體，软件总体根據[[GNU通用公共许可证|GPLv3]]授權條款分發<ref name="LICENSE">{{Cite web |title=audacity/LICENSE.txt at master · audacity/audacity |url=https://github.com/audacity/audacity/blob/master/LICENSE.txt |website=GitHub |language=en |last=audacity |access-date=2026-02-23}}</ref>。可在[[macOS]]、[[Microsoft Windows]]、[[Linux]]和其它[[作業系統]]上運作。

== 簡史 ==
Audacity於1999年由Dominic Mazzoni和Roger Dannenberg在卡內基梅隆大學創建，隨後於2000年5月作為自由軟體在SourceForge.net上發布。<ref>{{Citation|title=The Story Behind Audacity|url=https://www.youtube.com/watch?v=RMWNvwLiXIQ|accessdate=2024-05-09|language=zh-Hans-CN|archive-date=2024-05-16|archive-url=https://web.archive.org/web/20240516104102/https://www.youtube.com/watch?v=RMWNvwLiXIQ|dead-url=no}}</ref>

Audacity在2004年7月獲選為[[SourceForge]]當月最佳推薦專案<ref>{{cite web|title=Project of the Month, July 2004|url=https://sourceforge.net/blog/potm-2004-07/|date=2004-06-30|archive-url=https://web.archive.org/web/20190621122839/https://sourceforge.net/blog/potm-2004-07/|archive-date=2019-06-21|accessdate=2019-06-21|publisher=|dead-url=no}}</ref>，2007年7月選多媒體類的SourceForge.net 2007社群选择大奖<ref>{{cite web|title=2007 Community Choice Awards|url=http://sourceforge.net/community/index.php/landing-pages/cca07/|archive-url=https://web.archive.org/web/20080120140929/http://sourceforge.net/community/index.php/landing-pages/cca07/|archive-date=2008-01-20|accessdate=2019-06-21|publisher=|dead-url=no}}</ref>。2008年5月，Audacity被列入《PC World》雜誌美國版讀者和編輯選出的年度最佳產品100強列表。

2021年4月30日，Audacity被[[Muse Group]]收购。<ref>{{Cite web|title=Muse Group formed to support MuseScore, Ultimate Guitar; acquires Audacity|url=https://www.scoringnotes.com/news/muse-group-formed-to-support-musescore-ultimate-guitar-acquires-audacity/|website=Scoring Notes|date=April 30, 2021|language=en-US|last=Rothman|first=Philip|url-status=live|archive-url=https://web.archive.org/web/20210503004437/https://www.scoringnotes.com/news/muse-group-formed-to-support-musescore-ultimate-guitar-acquires-audacity/|archive-date=May 3, 2021|access-date=May 3, 2021}}</ref>

2021年7月，Audacity更新了其隱私政策，其中包含一個條款，允許Muse Group收集「法律遵循、訴訟和相關權威機構所需的數據」。這次更新引發了爭議，有觀點質疑Audacity或已轉變為間諜軟件<ref>{{Cite web|title=Audacity Open Source Audio Editor Has Become Spyware|url=https://www.slashgear.com/787715/audacity-open-source-audio-editor-has-become-spyware/|website=SlashGear|date=2021-07-05|language=en-US|last=Then|first=Ewdison|access-date=2024-05-09}}</ref><ref>{{Cite web|title=Audacity 究竟是不是間諜軟體？Muse 公開澄清隱私權爭議|url=https://digilog.tw/posts/1544|website=DigiLog 聲響實驗室|access-date=2024-05-09}}</ref>。面對此一爭議，Audacity撤銷了其資料共享的決策，並限制了在網絡上用於版本檢查與錯誤報告的資料傳送。<ref>{{Cite web|title=開發者們討論了針對 Audacity 項目提出的「提議」以解決隱私爭議問題|url=https://github.com/audacity/audacity/discussions/889|website=GitHub|language=en|access-date=2024-05-09|archive-date=2021-05-14|archive-url=https://archive.today/20210514192055/https://github.com/audacity/audacity/discussions/889|dead-url=no}}</ref>

== 接受情況 ==
[[CNET]]給Audacity打5/5顆星，並稱其「特性豐富而靈活」。<ref>{{cite web|url=http://download.cnet.com/Audacity/3000-2170_4-10058117.html|title=Audacity|date=2008-11-08|work=[[CNET]]|accessdate=2013-09-01|archive-date=2013-08-17|archive-url=https://web.archive.org/web/20130817220632/http://download.cnet.com/Audacity/3000-2170_4-10058117.html|dead-url=no}}</ref>

[[PC World]]的Preston Gralla稱，「如若你對製作音樂、編輯音樂及混音感興趣，那你會想要Audacity。」<ref>{{cite journal|url=http://www.pcworld.com/article/231663/audacity.html|last=Gralla|first=Preston|title=Audacity|work=[[PC World]]|date=2008-10-22|accessdate=2013-09-01|journal=|archive-date=2013-08-17|archive-url=https://web.archive.org/web/20130817085520/http://www.pcworld.com/article/231663/audacity.html|dead-url=no}}</ref>

[[TechRepublic]]的Jack Wallen強調了它的特性和易用性。<ref>{{cite web|title=Giving Audacity its due: An audio editor with serious functionality|url=http://www.techrepublic.com/blog/linux-and-open-source/giving-audacity-its-due-an-audio-editor-with-serious-functionality/|last=Wallen|first=Jack|work=[[Tech Republic]]|date=2011-07-18|accessdate=2013-09-01|archive-date=2013-12-24|archive-url=https://web.archive.org/web/20131224103337/http://www.techrepublic.com/blog/linux-and-open-source/giving-audacity-its-due-an-audio-editor-with-serious-functionality/|dead-url=no}}</ref>

[[PC Magazine]]的Michael Muchmore給其打3.5/5顆星，並說：「儘管不如Adobe、Sony、M-Audio旗下同類產品那樣靈巧，但Audacity在免費軟體中可說是特性萬分全面的了。」<ref>{{cite journal|title=Audacity 1.2 review|last=Muchmore|first=Michael|url=http://www.pcmag.com/article2/0,2817,2358860,00.asp|date=2010-02-05|accessdate=2013-09-01|journal=|archive-date=2013-08-28|archive-url=https://web.archive.org/web/20130828051044/http://www.pcmag.com/article2/0,2817,2358860,00.asp|dead-url=no}}</ref>

2021年5月，Audacity被Muse Group收購，並且在源始碼中加入基於[[Google分析]]與{{link-en|Yandex.Metrica}}的原始碼以回傳使用者資料，隨後引發大量使用者的負面批評，迫使Audacity縮限回傳資料用於錯誤回報及版本更新提示。<ref>{{Citation|title='A massive middle finger': Open-source audio fans up in arms after Audacity opts to add telemetry capture|url=https://www.theregister.com/2021/05/07/audacity_telemetry/|last=Speed|first=Richard|work=[[The Register]]|date=7 May 2021|access-date=8 May 2021|archive-url=https://archive.today/20210508145615/https://www.theregister.com/2021/05/07/audacity_telemetry/|archive-date=2021-05-08|url-status=live}}</ref><ref>{{Citation|title=Basic telemetry for the Audacity|url=https://github.com/audacity/audacity/pull/835|last=Vedenko|first=Dmitry|work=[[GitHub]]|date=4 May 2021|access-date=8 May 2021|archive-url=https://archive.today/20210507104723/https://github.com/audacity/audacity/pull/835|archive-date=2021-05-07|url-status=live}}</ref><ref>{{cite web|author=Tantacrul|date=13 May 2021|title=Actions we propose to take on PR #835 #889|url=https://github.com/audacity/audacity/discussions/889|url-status=live|archive-url=https://archive.today/20210514192055/https://github.com/audacity/audacity/discussions/889|archive-date=2021-05-14|access-date=14 May 2021|work=[[GitHub]]}}</ref><ref>{{Cite web|last=Speed|first=Richard|title=Audacity's new management hits rewind on telemetry plans following community outrage|url=https://www.theregister.com/2021/05/14/audacity_telemetry/|archive-url=https://web.archive.org/web/20210723180800/https://www.theregister.com/2021/05/14/audacity_telemetry/|archive-date=2021-07-23|access-date=2021-05-17|website=www.theregister.com|language=en}}</ref>Audacity新的隱私政策將在3.0.3版本生效。<ref>{{Cite web|title=Clarification of Privacy Policy · Discussion #1225 · audacity/audacity|url=https://github.com/audacity/audacity/discussions/1225|archive-url=https://web.archive.org/web/20210722125113/https://github.com/audacity/audacity/discussions/1225|archive-date=2021-07-22|access-date=2021-07-07|work=GitHub|language=en}}</ref>

== 局限 ==
