Audacity 是一款跨平台的波形编辑软件，用于处理各类音频、混编，是 Adobe Audition 的最佳替代者，完全免费，但是功能上毫不逊色。最新版本为 1.3.4 beta 测试版，新特性包括：

- A new welcome screen
- Enhanced Windows Shell integration, meaning you should be able to access Audacity from Windows dialogs like "open with."
- New keyboard commands and shortcuts
- The solo track button actually does what you'd expect and mutes all other tracks
- Metadata editor added for OGG, FLAC, and WAV/AIFF exports
