Audacity 4.0 Beta 4 has been released, skipping Beta 3 entirely and featuring a significant migration from wxWidgets to Qt6, resulting in a major UI overhaul and improved performance. Key updates include the introduction of Windows ASIO support, expanded codec compatibility with FFmpeg 9, and restored features like the Bass and Treble EQ, along with enhanced stability through crash-safe plugin detection. The new version also maintains backward compatibility with Audacity 3 projects and offers cloud saving through Audio.com, ensuring a smoother transition for users. With a focus on modernizing the application while addressing community feedback, the team is aiming for a stable release soon, despite the risks associated with the mid-cycle UI rewrite

Audacity 4.0 Beta 4 Ships With Qt6 UI, Windows ASIO, and Legacy Imports

Audacity 4.0 Beta 4 launched today, skipping Beta 3 entirely after 689 commits reshaped 300 files in a rapid development push. The build cements the migration from wxWidgets to Qt6 by reusing the framework from MuseScore Studio 4, delivering a major UI overhaul, native ARM64 support, and offline build capabilities. New inclusions include Windows ASIO support, FFmpeg 9 for expanded codec compatibility, a restored Bass and Treble EQ, and crash-safe plugin detection that stops broken extensions from taking down the host. Muse Group's overhaul retains backward compatibility with Audacity 3 projects via clip-based workflows and Audio.com cloud saving, though the skip of a beta cycle suggests the team is racing toward a stable release with untested edge cases still pending.
