Audacity 4.0 测试版发布：全新 Qt 界面更美观
Audacity 4’s first public beta arrived this month with the biggest design change the iconic open-source audio editor has seen in decades. The audio editor’s interface, built on wxWidgets since the project began, now runs in Qt. However, the audio engine which handles file I/O, project storage and the built-in effects, uses the older codebase, wired up to the new frontend via a module called au3wrap. In a sense, Audacity 4 is a new look atop the same core engine, although the Github changelog choose to frame it as a “ground-up rewrite” in Qt, that appears to be only relate to the UI. Either the, the new look (and its new logo) will go a long way to addressing jibes that the Audacity looks dated.
本月，Audacity 4 的首个公开测试版正式发布，带来了该标志性开源音频编辑器数十年来最大的设计变革。自项目启动以来，该编辑器的界面一直基于 wxWidgets 构建，而现在已迁移至 Qt 框架。不过，负责处理文件 I/O、项目存储和内置效果的音频引擎仍沿用旧代码库，并通过名为 au3wrap 的模块与新的前端进行连接。从某种意义上说，Audacity 4 是在同一核心引擎上换了“新装”。尽管 GitHub 的更新日志将其描述为“基于 Qt 的彻底重写”，但这似乎仅限于用户界面（UI）。无论如何，全新的外观（及其新 Logo）将极大地改善人们对 Audacity 界面陈旧的诟病。
Beyond visual changes, there are plenty of new and improved features to check out. Spectral editing and a more customisable UI A redesigned envelope tool handles gain curves with drag-and-reshape controls; spectral editing lets you select frequency regions in the spectrogram directly to apply effects to a specific band; and a new metadata editor handles track title, artist, etc tags before export. Lead-in recording also makes it debut (previously known as punch and roll). This lets you record over a section of audio without affecting whatever comes after it.
除了视觉上的变化，还有许多新功能和改进值得关注。在频谱编辑和更具自定义性的 UI 方面，重新设计的包络工具通过拖拽调整控制来处理增益曲线；频谱编辑功能允许你在频谱图中直接选择频率区域，从而对特定频段应用效果；此外，新的元数据编辑器可在导出前处理音轨标题、艺术家等标签。“前导录音”（Lead-in recording，即以前的“穿插录音/Punch and Roll”）也首次亮相，它允许你在不影响后续音频的情况下覆盖录制某一段音频。
Working on multiple projects? They can now stay open at once, and you can copy clips between them. Nyquist and VST3 plugins are supported across all platforms, with AudioUnits on macOS and LV2 on Linux. There’s also built-in cloud saving via Audio.com (and it WILL nag you about this unless you disable the welcome dialog), some new layout options (customisable workspaces, coloured clips, etc), plus a new dashboard for managing your projects.
需要同时处理多个项目？现在它们可以同时保持打开状态，并且你可以在不同项目之间复制剪辑。Nyquist 和 VST3 插件在所有平台上均得到支持，macOS 上支持 AudioUnits，Linux 上支持 LV2。此外，它还内置了通过 Audio.com 进行云端保存的功能（除非你禁用欢迎对话框，否则它会不断提醒你），并提供了一些新的布局选项（可自定义工作区、彩色剪辑等），以及一个用于管理项目的新仪表板。
What about Audacity 3.x compatibility? You can open Audacity 3 project files in Audacity 4, with clips, tracks and labels carried across intact. There’s no indication that things work in reverse; given how much has changed, it’s safer to assume Audacity 4 projects won’t open in 3.x. Keep that in mind if you plan to try a 3.x project in 4.0 and make changes that get saved. Do back up your projects before making any changes.
关于 Audacity 3.x 的兼容性如何？你可以在 Audacity 4 中打开 Audacity 3 的项目文件，剪辑、音轨和标签都能完整保留。目前没有迹象表明可以反向兼容；考虑到变化巨大，假设 Audacity 4 的项目无法在 3.x 中打开会更稳妥。如果你打算在 4.0 中尝试 3.x 项目并进行保存修改，请务必记住这一点。在进行任何更改之前，请务必备份你的项目。
A number of Audacity 3.x features are not included in 4.0 (beta 2). Tempo tracks, LADSPA plugins and Vamp analysers are gone. There’s no word (yet) if they’ll be back before the stable release. If you need ’em, stay on the 3.x branch as it’s stable and maintained. On that note, Audacity 3.7.8 was released alongside the 4.0 beta. A maintenance release with fixes for multichannel FLAC file importing, preset loading in the Distortion effect and, on Linux, a wxGTK interface that looks better on HiDPI displays.
Audacity 4.0 (beta 2) 中并未包含 Audacity 3.x 的部分功能。速度轨道（Tempo tracks）、LADSPA 插件和 Vamp 分析器已被移除。目前尚不清楚它们是否会在正式版发布前回归。如果你需要这些功能，请继续使用 3.x 分支，因为它稳定且仍在维护中。顺便一提，Audacity 3.7.8 已随 4.0 测试版一同发布。这是一个维护版本，修复了多声道 FLAC 文件导入、失真效果器中的预设加载问题，并在 Linux 上提供了在 HiDPI 显示器上显示效果更好的 wxGTK 界面。
Can I test Audacity 4.0 beta? You can download Audacity 4.0.0 beta 2 for Windows, macOS and Linux from the Audacity.com/next web page or head to the project GitHub. For the latter, there’s an Intel/AMD 64-bit AppImage to try, but no ARM64 build (yet; there’s one for Windows). As a beta there’s no assurance of stability. I encountered a number of hard crashes just poking around to take a few screenshots, so this build isn’t ready for anything you can’t afford to lose. But the broad strokes are present, and they are looking good – question is, do they sound good to you? Let me know in the comments.
我可以测试 Audacity 4.0 测试版吗？你可以从 Audacity.com/next 网页或项目 GitHub 下载适用于 Windows、macOS 和 Linux 的 Audacity 4.0.0 beta 2。在 GitHub 上，有一个适用于 Intel/AMD 64 位的 AppImage 可供尝试，但目前还没有 ARM64 版本（Windows 版已有）。作为测试版，它无法保证稳定性。我在截屏测试时遇到了多次强制崩溃，因此该版本不适合处理任何你无法承受丢失的数据。但大体框架已经呈现，看起来不错——问题是，它们听起来对你来说好用吗？欢迎在评论区告诉我。
