Audacity真的是免费的吗? 为什么?
是的，Audacity 是完全免费的、开源的软件。你可以将之使用于任何合法的目的，包括个人、商业或教育用途，并可以在不同的计算机上随意安装它。您还可以遵照 GNU通用公共许可证 发放、销售它，或者修改供自己使用。
Audacity 的作者们决定在 GPL 下发布的原因有很多。我们有些人是出于慷慨；有些人出于道德上的理由，因为我们觉得所有的软件应该是免费的；另外一些人认为这个世界上自由软件和专有软件都应该有其一席之地。
Audacity 是免费的原因之一，是因为这将是使之更流行和实用。然而，另一个原因则是出于鼓励合作。由于Audacity的免费许可证，几十个来自世界各地的朋友贡献了代码、bug修复、文档和图片。
我们欢迎您进行捐助以支持Audacity的发展。
Audacity包含间谍软件，恶意软件或者广告吗？
不。 如果你是从我们的网站 http://web.audacityteam.org 下载的Audacity，那么一定不包含。请访问 virustotal.com 搜索页这个第三方认证网站查看 Audacity 的验证结果，打开刚才的链接后，输入"audacity" (不包含引号)，然后点击 "Search it!" 即可。访问 siteadvisor.com查看 http://web.audacityteam.org 的检测报告。
从美国下载的 Audacity 是完全免费且开源。它是由几个非盈利志愿者团队开发的，源代码可供任何人学习或使用。
不过，有时候杀毒软件可能会将 Audacity 的windows (.exe)安装程序误报为病毒，这是因为此程序是一个压缩安装程序。有时候当你从临时存储位置执行程序时杀毒软件也会阻止。你可以将安装程序下载到你的桌面然后在那里运行。如果担心此安装程序的安全性，你可以选择下载zip版本的 Audacity，然后检测是否是病毒。请将 Audacity 误报信息反馈给您使用杀毒软件的开发商，好让他们修改他们的病毒识别库。
另，新版本 IE 浏览器中的 SmartScreen 过滤器可能说 Audacity 不是 "commonly downloaded" 并请求确认下载。这个警告很正常，通常是Audacity 发布新版或者你在尝试下载 (如果你刚好是在干这些) 。之所以有此警告，是因为 IE 会检查 Microsoft 的数据库并获取 "IE 用户的常见下载列表"，以此确定哪些软件是受信软件（并检查间谍软件）。要想获取更多帮助，请查看 SmartScreen FAQ。
我可以分发 Audacity 的副本吗?
你可以遵照 GNU 通用公用许可协议发布 Audacity ，按照此许可你可以修改，复制或者重新出售此程序，但是必须使用和原软件相同的许可并公开源代码。我们要求所有经销商都要给予 Audacity 一定谢意，可以是给他们的产品添加一些有价值的东西 (例如，视频教程或者公用许可下发布的声音示例文件)，以此帮助客户更方便地学习使用产品。详见 给经销商的建议。
有人在 eBay 上出售 Audacity ，这合法吗？
销售Audacity是合法的。只要销售者遵循 GNU 通用公共许可证 (GPL)并发布源代码。如果分发者修改了 Audacity，因为商标问题他们的程序名不能再是 Audacity。请查看我们的 许可 页获取详细信息。
有些人使用不同的名字发布未经过修改的 Audacity，或者不发任何关于我们的链接及致谢 - 按照当前的 GPL 协议很难预防此情况发生。如果您购买了一个产品，最后发现它就是 Audacity，这时你觉得很不公平，我们鼓励您 申请退款或者投诉。请查看"我可以分发 Audacity 的副本吗？" 了解我们对于分发商的要求。
如果你担心 Audacity (未经修改或其他)没有附加 GPL 许可却用来销售，或者未提供任何源代码，请私下发邮件告诉我们。
如果你想获取 Audacity CD: 请访问Audacity CD 页面，上面有免费 ISO 下载链接，也有供应商提供的包含 Audacity 以及其他开源软件廉价光盘。
A search result misled me into paying for an Audacity download. What can I do?
If you search for Audacity on the internet, you will often see "sponsored results" that are links to companies selling Audacity (or the right to access it) for money. For example there may be a "free" download but the "small print" will commit you to a paid subscription to buy software or services every month. Or the company may guarantee to supply the "very latest version" when their version is out-of-date, or sometimes the download is really is "free" but carries spyware or viruses.
You should avoid these advertisers and only download Audacity from http://web.audacityteam.org/ .
If the advertisement is provided by Google and does not comply with their terms you can complain about it to Google here. "Audacity" is a registered trademark in the USA and recognised as such by Google, therefore if advertisements on Google.com include "Audacity" in the advertisement or link text you may report this to Google. You can also complain to Google if the advertisement did not "accurately represent the product or service" - please tell Google in what way the advertising was not an accurate representation.
If you paid money by credit card due to a fraudulent advertisement, you may be able to initiate a chargeback with your credit card company. You need to show that the advertising and website you visited was misleading. Generally you should try to sort out a refund with the retailer first, but often they are very hard to contact and there is a time limit of only a few days on requesting a refund.
Audacity isn't displaying in the expected or desired language. Can I change this?
Audacity can display in many non-English languages. The language Audacity uses on first run is determined by the language the operating system uses. Note that on Windows, the Audacity installer only sets the language for the installer to run in, not the language Audacity runs in.
If you can read the language Audacity is currently running in, it's easy to change to another language. Open the , then choose from the list on the left. Now choose the specific language required from the "Language" box, then click OK. Most of the Audacity interface will change language at once, but a very few interface elements will change next time you restart Audacity.
If Audacity is running in an unfamiliar language, please see this page in the Manual.
Will there be a version of Audacity for iPod, iPad or other smartphones or tablet computers?
Current versions of Audacity work internally with uncompressed audio to permit high quality editing with a wide range of effects. This requires more processing power and disk space than is available on most mobile devices. Also the wxWidgets interface library we use only has limited support for mobile operating systems and small screen resolutions.
Therefore, considerable rewriting of Audacity and its interface will be required before Audacity will work on portable music players like iPod, smartphones like iPhone, tablet computers like iPad or any of the Nexus devices running Android.
However, Audacity in principle does support a tablet PC running Windows XP (including Windows XP Tablet PC Edition), Vista, Windows 7 or Windows 8 (including Microsoft's "Surface with Windows 8 Pro" tablet). Audacity will not run on the Windows RT operating system which ships on devices running ARM architecture (such as Microsoft's Surface with Windows RT tablet).
There are many alternatives available for lightweight recording or editing on mobile platforms:
- Android: TapeMachine Recorder
- iPhone, iPod Touch and iPad:
- Symbian: Mixx Mobile
- Windows Mobile: WavePad for CE (free).
How accessible is Audacity for motion- or visually-impaired users?
Audacity has numerous keyboard shortcuts which can be customised in the Keyboard Preferences. Most of Audacity can be wholly or partially used without a mouse, with excellent keyboard navigation of the selection. A few features currently have no keyboard alternatives, notably clips, Time Tracks and the Tools Toolbar tools except Selection Tool.
Audacity works well with most screen-reader programs on Windows (including Jaws, Window-Eyes and NVDA) and with VoiceOver on Mac. However a few features, notably Label Tracks and Meter Toolbars aren't read. We still have to improve screen-reader support for Linux.
For more information, see Accessibility. There are useful links to free screen readers and support resources for the blind on our Wiki page Audacity for blind users.
What features does Audacity have for speech transcription or speech recognition?
Audacity is not specialised transcription or speech recognition software, but has some useful features for those transcribing speech manually.
- You can use Transcription Toolbar to play audio more slowly (also lowering the pitch).
- You can add labels at the playback position using CTRL + M (or COMMAND + . on Mac) then type into the label. Use to export a tab-delimited plain text file containing the text and audio position of each label.
- Audacity has many other configurable keyboard shortcuts that can be used to control playback and editing. However as yet Audacity has no global shortcuts that work even if you have focus in another program. Some mouse gestures (not yet configurable) can also be used.
Foot pedals: Audacity has no built-in support for foot pedals, but if you can install a suitable driver so that the pedal delivers mouse clicks or key strokes, Audacity can be controlled by those. The pedal manufacturer might be able to assist, or some pedals (for example, Vpedal or X-keys) already come with software to map pedal buttons to specific keystrokes. Alternatively if your pedal is recognised by the computer as a Game Controller or Human Interface Device, you may be able to use third-party software such as AutoHotKey (Windows) to map pedal buttons to keystrokes. USB Overdrive can do the same on Mac for a USB pedal.
Speech recognition: If you are looking for software that can recognise microphone input or speech in an audio file and convert it automatically to a text file, see Wikipedia's list of speech recognition software.
Does Audacity run on 64-bit systems?
There is no 64-bit version of Audacity, but in principle it should run on 64-bit systems, subject to having appropriate drivers for the sound device. Sufficient RAM must be available to run Audacity smoothly and support the greater memory requirements of 64-bit systems compared to 32-bit.
Windows and Linux 64-bit
On 64-bit versions of Windows XP, Windows Vista, Windows 7, Windows 8 and Linux, sound device drivers specific to the 64-bit operating system are essential. If upgrading from a 32-bit to 64-bit operating system, a 64-bit capable computer is required, and the sound device drivers must also be updated to a 64-bit version.
Users upgrading from 32-bit Windows XP to 64-bit Windows Vista or 7 should make especially sure their computer is well above Audacity's minimum system requirements for Windows.
Mac OS X 64-bit
OS X 10.5 and later support both 64-bit and 32-bit processors equally well, with few if any issues with the supplied system drivers.
Does Audacity support low latency ASIO drivers?
Licensing restrictions prevent us including ASIO support in released versions of Audacity, but Audacity can be compiled with ASIO support for private, non-distributable use. See ASIO Audio Interface on the Wiki for details.
How do I find which Audacity version I have, and if this is the latest version?
Click (or on a Mac ) to check the version of Audacity you are running, then visit our Download page to view the latest releases. You can subscribe here to receive an email whenever we release new versions of Audacity.
Why doesn't Audacity ship with an MP3 encoder?
Unfortunately, the algorithm to encode or create MP3 files is patented and Audacity would not be able to include an MP3 exporting algorithm without either charging a fee or potentially violating copyright law in some countries.
As a compromise, Audacity comes with the ability to use other MP3 encoders, which you must download separately. It is up to you to make sure you are in compliance with any licensing restrictions imposed by MP3 encoders.
To install LAME, see "How do I download and install the LAME MP3 encoder?".
How can I help to improve Audacity?
