Audacity 4.0.0 ships with a complete UI rebuild on Qt, adding a Home screen, configurable Workspaces, non-destructive clip trimming, multi-clip selection, clip grouping, a dedicated splitting tool, and clip envelopes for volume/fade adjustments without altering originals. Existing keyboard shortcuts and Audacity 3 projects are preserved.

Why: If you produce podcasts, demos, or audio content for your startup and have been avoiding Audacity due to its dated interface, version 4 is now worth a fresh look as a free alternative to paid DAWs — the non-destructive trimming and clip envelopes alone close two long-standing workflow gaps.

Audacity 4.0 rebuilds the entire UI on Qt with native high-DPI rendering, replaces the old Select/Envelope/Draw/Multi-tool modes with context-sensitive interactions, and introduces a new clip-editing model where clips can be directly selected, grouped, moved freely between mono/stereo tracks, and overlapped. Sync-Lock has been removed; splitting now uses a dedicated tool (hold S). Workspaces (Modern, Classic, Music) and light/dark/high-contrast themes are new.

Why: If you use Audacity in any pipeline (podcasts, audio datasets for ML, demo recordings), expect to relearn key workflows—tool modes are gone, clip handling is fundamentally different, and some controls have moved. No action needed if you don't use Audacity.
