GoKawiilAudacity 4.0 launches with Qt rewrite but drops several Audacity 3 features
Audacity 4.0 has shipped with a rebuilt Qt-based interface, a new clip-editing model, customizable workspaces, native high-DPI rendering, and a new AUP4 project format. Official Windows builds also gain ASIO playback and recording support alongside broader changes to how the app handles recording, playback, plugins, and projects.
GoKawiil's interpretation of the reporting above, not reported fact.
The rewrite modernizes an aging codebase but strips out tools like Time Tracks, MIDI tracks, the Mixer, Macro Manager, scripting pipe, VAMP/LADSPA plugin support, and play-at-speed that longtime users rely on. That gap could push some users to stick with Audacity 3 until developers restore parity, a reminder that ground-up rewrites of popular open source tools often trade short-term functionality for long-term architecture gains.
- Audacity 4.0 introduces a rebuilt Qt interface, new clip editing, and a new AUP4 project format.
- Windows users gain official ASIO playback and recording support.
- Several Audacity 3 features, including MIDI tracks and macros, are missing for now but planned for future updates.
