What is Audacity?

Audacity 4.0 ships a full Qt rebuild — a break from 20+ years of wxWidgets.

Audacity 4.0 is out, replacing the entire application framework with Qt. The new version introduces a substantially different clip editing model where clips are selectable, groupable, and movable between mono and stereo tracks, along with a new .aup4 project format, ASIO support on Windows, and a workspace system for UI layout persistence. The 3.7.x series continues in parallel — 3.7.9 backported ASIO and FFmpeg 9 support — indicating a deliberate dual-track approach rather than an abrupt cutover.

What is Proto.io?

Proto.io's public output has dwindled to occasional customer case studies.

The feed is sparse and old: one case study from mid-2025 (Trenaro's AI learning prototype), another from late 2023 (Travelnaut), and the rest is a 2022 cluster of design listicles and prototyping how-tos. There are no product release notes, no feature posts, and no recurring publishing cadence. The pattern reads like a tool in maintenance mode that still picks up occasional notable customers.

Audacity vs Proto.io: editorial side-by-side

Audacity 4.0 ships a full Qt rebuild — a break from 20+ years of wxWidgets.

◆ Current state

Audacity 4.0 is out, replacing the entire application framework with Qt. The new version introduces a substantially different clip editing model where clips are selectable, groupable, and movable between mono and stereo tracks, along with a new .aup4 project format, ASIO support on Windows, and a workspace system for UI layout persistence. The 3.7.x series continues in parallel — 3.7.9 backported ASIO and FFmpeg 9 support — indicating a deliberate dual-track approach rather than an abrupt cutover.

◆ Where it's heading

Audacity is executing an architectural break from its legacy codebase, but scoped carefully: several 3.x features (MIDI tracks, Macro Manager, VAMP/LADSPA hosting, the scripting pipe) are not yet in 4.0, signaling an iterative port strategy. The dual-release model confirms the team won't abandon the 3.x base abruptly. Closing the 4.0 feature gap is the obvious near-term focus.

◆ Prediction

The next several 4.x releases will focus on restoring missing 3.x features — MIDI tracks and the Macro scripting interface are the most-cited gaps. Stability fixes across platforms are also expected given the scale of the framework change.

0.0

Proto.io's public output has dwindled to occasional customer case studies.

◆ Current state

The feed is sparse and old: one case study from mid-2025 (Trenaro's AI learning prototype), another from late 2023 (Travelnaut), and the rest is a 2022 cluster of design listicles and prototyping how-tos. There are no product release notes, no feature posts, and no recurring publishing cadence. The pattern reads like a tool in maintenance mode that still picks up occasional notable customers.

◆ Where it's heading

Without product-change posts in the visible window, the trajectory signal is mostly negative: long gaps between posts, no roadmap commentary, no feature drops. The 2025 Trenaro case shows Proto.io still being chosen for AI-product prototyping, but doesn't indicate the platform itself is evolving in that direction. The most defensible reading is a stable, low-investment tool.

◆ Prediction

Most likely next signal is another sporadic case study rather than a product release. A material shift would be visible as a return to a regular publishing cadence — until then, expect quiet.
