3.5.022 Apr 2024 14:23 major feature: Major changes Cloud project saving We've introduced a new cloud-saving feature that allows you to save your Audacity projects to This allows you to work from any device, share collaborate with others and restore previous versions if something went wrong. Automatic tempo detection Audacity can now automatically detect the tempo of imported loops, and adjust them to be in tempo. Tempo detection is done via both audio analysis and metadata checking. If you want to prepare your loop for automatic tempo detection without relying on audio analysis, both acidizer tempo tags or simply writing "123 bpm" anywhere into the filename work. Automatic tempo detection can be turned off via Preferences - Import/Export. Pitch shifting You now can non-destructively change the pitch of a clip by holding Alt and pressing the Up and Down arrow keys. Alternatively, you can click on the overflow menu (...) and select "Pitch and speed...". When changing the pitch this way, an arrow in the UI indicates how much you've shifted it. Other changes Additions Added an option to skip plugin scanning to Preferences - Effects. Added an overflow menu, as well as speed and pitch indicators to clips. Added subtitle formats for labels. Export to WebVTT and SubRip and import of SubRip files is now supported. (Thanks, Pokechu22 and Larry Bordowitz!) Changes Reworked the plugin manager. Improved accessibility. (Thanks, David Bailes!)
