Audacity 3.7.5 shipped this week, and for the first time, the popular open-source audio editor runs natively on Windows 11 ARM64 devices. No emulation required. The update closes a long-standing gap for users of Snapdragon-powered laptops like the Surface Pro X, delivering a crucial performance boost and eliminating the overhead that has plagued x86 emulation on Windows on ARM.

This release follows Audacity’s existing native builds for Linux on ARM and Apple Silicon, meaning the cross-platform editor now offers first-class support across all major ARM ecosystems. But the arrival is bittersweet: plugin users are left waiting, as VST and OpenVINO remain incompatible with the ARM64 build, and the development team itself has limited hardware for testing. The news underscores both the accelerating momentum of Windows on ARM and the stubborn friction that still deters pro-level adoption.

What’s Actually New in Audacity 3.7.5

The headline feature is clear: a dedicated installer that targets ARM64 processors inside Windows 11 machines. Previously, users had to rely on Microsoft’s x86 emulation layer, which saps performance, spikes CPU usage, and occasionally introduces instability during real-time audio processing. Native code changes the equation—audacity.exe now speaks directly to the ARM instruction set.

Beyond the architecture leap, the release notes list a handful of critical bug fixes:
- FLAC importer now handles 32-bit PCM audio, resolving import failures with high-resolution files.
- A crash triggered when rendering the spectrum view has been patched.
- The registration window no longer steals focus and vanishes unexpectedly.
- A crash on importing WAV files shorter than 7 milliseconds—an edge case that could break batch processing—is fixed.
- The Macro Wizard, a tool for automating repetitive edits, no longer crashes mid-execution.

These fixes, while small in scope, address real pain points reported by the user base. Together with the ARM64 support, they make 3.7.5 the most stable release yet for Windows on ARM adopters.

The ARM Gap: Why This Matters More Than You Think

ARM architecture excels at energy efficiency. Snapdragon X Elite and X Plus chips, as well as older Microsoft SQ processors, sip power while delivering enough grunt for multitrack editing and effects processing. A native Audacity build means those efficiency gains translate directly into longer battery life, cooler palm rests, and—on fanless designs—silent recording sessions. For podcasters, field recorders, and students editing audio on the go, that’s a tangible upgrade.

Contrast this with emulation. Under x86 emulation, even simple operations like applying a noise gate or rendering a long timeline can peg CPU usage, drain battery, and introduce audible dropouts. The compatibility layer has been a necessary evil, but it has also held back Windows on ARM from being taken seriously for creative work. Audacity’s move chips away at that reputation.

The Limitations That Still Sting

But the launch isn’t all champagne corks. The Audacity team has been transparent about what’s missing, and the list is significant enough to give power users pause.

No VST or OpenVINO Plugins

Audacity’s plugin architecture—spanning VST2, VST3, and the AI-powered OpenVINO effects—does not yet work with the ARM64 build. The code paths haven’t been ported, and the team offered no timeline for when they might be. That means anyone relying on third‑party EQs, compressors, virtual instruments, or noise reduction suites will either need to stick with the x86 version (and its emulation overhead) or wait. The official statement: “Presumably that’s down the road,” but no commitment.

FFmpeg Compatibility Landmines

Audacity leans on FFmpeg for importing and exporting a wide range of formats, from AAC to AC3. The ARM64 build requires the ARM64 variant of FFmpeg. Many users—especially those who installed FFmpeg via Chocolatey or other package managers—likely have the x86 version. The mismatch causes silent failures: files won’t open, exports error out. The fix is manual: download the correct ARM64 FFmpeg binaries and point Audacity to them. It’s a minor hurdle for tech-savvy users but a stumbling block for novices.

Windows 11 Only

If you’re nursing an older Windows 10 ARM device, or clinging to the long-dead Windows RT, you’re out of luck. The build targets Windows 11 on ARM exclusively. This aligns with Microsoft’s own support lifecycle, but it leaves a handful of users on legacy hardware stranded.

Developer Reality Check: Limited Hardware, Open Invitation

Perhaps the most candid note in the release commentary is the developers’ admission that they don’t have much ARM hardware to test on. The team asked early adopters to report bugs and share feedback, framing the release as a community-driven effort rather than a polished final product. This is the open-source ethos in action, but it also means the ARM64 build may ship with quirks that a well-funded commercial team would have ironed out.

The request for feedback is pragmatic. Windows on ARM devices are still a fraction of the total install base, and developer access to representative hardware is spotty. Collaboration between users and contributors has always been Audacity’s engine. Now, it’s also the testing department.

The Long Road to ARM Parity on Windows

When Apple switched to its own ARM-based silicon in 2020, most major creative apps—Logic Pro, Ableton Live, Adobe Audition—shipped native versions within months. Microsoft’s ARM push, in contrast, has been a slow burn. The first Windows RT tablet appeared in 2012, followed by Windows 10 on ARM in 2017, and yet native software remains a trickle. Audacity joining the party is noteworthy precisely because the party has been so sparsely attended.

Microsoft has made strides. Windows 11’s x86-64 emulation is markedly better than its predecessor, and the new Prism emulator in 24H2 boosts compatibility further. But emulation still incurs a penalty, and for latency-sensitive audio work, that penalty is unacceptable. Native apps are the only way to unlock the full potential of the hardware, and each new title—especially a free, open-source one—validates the platform for a broader audience.

How Audacity Stacks Up Against the Competition

On x86 Windows, Audacity isn’t alone. Reaper, Cakewalk, and even Adobe Audition offer robust audio editing. But on ARM? The landscape is barren. Most commercial DAWs either lack ARM builds or run only under emulation. Audacity’s native release gives it an uncontested niche: a free, capable audio editor that runs smoothly on every Surface Pro X, Lenovo ThinkPad X13s, and Samsung Galaxy Book 2 Edge sold in the last three years.

That first-mover advantage could cement Audacity’s place in a growing market. As Qualcomm’s Snapdragon X series pushes into mainstream laptops, and as more enterprise fleet customers adopt ARM for battery life, the demand for native creative tools will rise. Audacity is now positioned to capture those users, many of whom may have previously dismissed Windows on ARM as a toy for Office and Edge.

A Brief History of Audacity’s Controversy

No coverage of Audacity is complete without acknowledging its turbulent recent history. In 2021, the project’s new owners (Muse Group) proposed telemetry features that many users saw as spyware. The backlash spawned multiple forks: Tenacity, Audacium, and others promised a return to the pure, privacy-respecting roots. The fork movement made headlines, and many predicted Audacity’s decline.

Four years on, the dust has settled. Most forks have gone dormant. Tenacity still exists, but its release cadence is glacial. Audacity, meanwhile, has maintained regular updates, added features like non-destructive editing and cloud saving, and now leads the ARM migration. The telemetry that ignited the firestorm is opt-in, not mandatory. In practice, the community’s fears didn’t materialize, and Audacity remains the de facto open-source audio editor—warts and all.

Practical Steps for Windows on ARM Users

If you’re ready to take Audacity 3.7.5 for a spin on your ARM PC, here’s a quick checklist:
- Confirm you’re on Windows 11 22H2 or later (Settings > System > About).
- Download the official ARM64 installer from audacityteam.org—not the generic Windows version.
- Install FFmpeg for ARM64 separately. Avoid package managers unless they explicitly offer the ARM variant. The Audacity manual has a guide.
- Skip VST plugins for now; use Audacity’s built‑in effects, which have been expanding steadily.
- Enable the “Check for updates” option to catch future releases that may add plugin support.
- If you encounter crashes or oddities, report them on the Audacity forum or GitHub. The developers are actively seeking this feedback.

Looking Forward: What’s Next for Audacity on ARM?

The roadmap remains unofficial, but the direction is clear. The team has hinted that plugin support is a priority, and they’ve already tackled the heavy lifting of the ARM64 port itself. Subsequent releases will likely fill the FFmpeg compatibility gap with better auto-detection or bundled binaries. VST support may take longer, as it involves bridging two plugin architectures (x86 and ARM) or waiting for plugin vendors to compile their own ARM64 builds—a chicken-and-egg problem.

The wider Windows on ARM ecosystem will also evolve. Microsoft’s Project Volterra, now the Windows Dev Kit 2023, is an ARM desktop box meant to seed developer adoption. As more developers get their hands on capable ARM hardware and toolchains improve, the native app library will expand. Audacity’s move might be early, but it’s far from premature.

Conclusion

Audacity 3.7.5 is a milestone, not a finish line. For the first time, Windows 11 ARM users can edit, record, and process audio without the emulation tax. The performance and efficiency gains are real, and they’ll be felt immediately by anyone who’s wrestled with a sluggish timeline on a Snapdragon laptop. But the missing plugins, the FFmpeg setup hassle, and the limited developer testing mean this release is a foundation, not a full-featured replacement for traditional x86 workflows.

Still, the optics matter. A high-profile open-source project throwing its weight behind Windows on ARM signals to other developers that the platform is viable. It’s a calculated bet that the audience for ARM-native creative tools will grow—and that Audacity will be ready when they arrive. For now, it’s a welcome addition, even if it’s not yet the complete package.
