更新日志

3.6.0

Major changes

Master effects
Audacity now features master effects. Master effects are effects which apply to the entire project at once. More information can be found at Using master effects & realtime effects.

New compressor and limiter
A new compressor and limiter has been added, replacing the previous versions. A gain reduction history has been added to these effects when they're used as a realtime effect.
Factory Presets suitable for a wide range of use cases for these effects have been provided by Vladislav Isaev and Marek Iwaszkiewicz, available via the Presets & Settings button.

New themes
Audacity now features new and improved dark and light themes. You can switch between themes via Preferences -> Interface. The theme previously used still is around as the Classic theme, and themes even older than that can be optionally installed as custom themes from here.
Updated instructions on creating custom themes can be found here.

Increased performance
Audacity is now quite a bit snappier than before, especially when working on larger projects and on larger screens.
