Audacity 3.7.4 arrives as a small but consequential update, sharpening everyday workflows and tightening the reliability of this long‑standing open‑source audio editor across Windows, macOS, and Linux.
The headline for this maintenance release is stability. Crashes tied to real‑time effects with delay compensation, edge‑case clip joins that could unexpectedly remove video clips from a timeline, and a shutdown crash on large unsaved projects are all addressed. Just as importantly, Audacity’s user experience gains polish through a new welcome/what’s‑new screen and practical fixes such as accurate waveform rendering on clipped material and an effect preview that works even when a track is muted.
For audio editors juggling deadlines, the difference between a good tool and a dependable one often shows up in the margins—how the app behaves when the session is heavy, when a plug‑in is misbehaving, or when a common action intersects with a corner case. Audacity 3.7.4 is that kind of margin‑tightening release.
This change is deceptively powerful. It keeps the mixing context intact—mute remains mute for playback—while streamlining the micro‑loop of “open effect, tweak, preview, repeat.” It also reduces the temptation to bounce between solo/mute states during sound design, which can cause accidental timeline changes elsewhere.
Practical tip:
For dialog editors and educators, this visual reliability also has a training benefit: the waveform now more consistently matches the sonic reality of clipping, reinforcing gain staging best practices.
3.7.4 continues that trajectory. It does not chase marquee features but removes friction where it accumulates:
But those are forward‑looking wishes. Today’s 3.7.4 release meets users where they work, not where the roadmap dreams.
For editors who depend on Audacity as a daily driver, that’s exactly the right kind of progress.

A steadier editing foundation
Fixing the high‑impact crashes
Two crash scenarios addressed in 3.7.4 are especially notable for producers who lean on Audacity’s real‑time effects stack:- Real‑time effects with delay compensation: Plug‑ins that introduce latency require the host to compensate so tracks remain in sync. Prior to 3.7.4, Audacity could crash when certain plug‑ins activated latency reporting. The fix removes a nagging uncertainty when auditioning or printing chains that include look‑ahead limiters, linear‑phase processors, or AI effects that buffer audio.
- Closing large unsaved projects: Sessions with many clips, tracks, or long recordings stress memory and autosave logic. A crash at shutdown risks data loss and breaks trust. The patch here restores predictable teardown behavior, particularly on systems that run long recordings or batch edits.
The clip‑join edge case
Joining two clips with pitch adjustment and losing video clips in the process was an alarming, if rare, failure mode. Many users import video to extract or realign audio, and the timeline must treat those video objects with extreme care even when the focus is audio editing. By correcting the join logic, 3.7.4 reduces the risk of destructive surprises in mixed media projects.Workflow polish that saves real time
Effect preview that ignores mute (just for the audition)
Auditioning a filter or dynamics processor often happens after the track has been muted for a quick A/B or to focus on another source. Previously, this could lead to confusing silence when opening an effect and tapping Preview—because the track was muted, there was nothing to hear. Audacity 3.7.4 changes that behavior so the preview path works even if the track is muted, without altering the track’s mute state in the session.This change is deceptively powerful. It keeps the mixing context intact—mute remains mute for playback—while streamlining the micro‑loop of “open effect, tweak, preview, repeat.” It also reduces the temptation to bounce between solo/mute states during sound design, which can cause accidental timeline changes elsewhere.
Practical tip:
- Leave the track muted while you audition a filter with Preview.
- When satisfied, Apply the effect; the track stays muted for the broader arrangement.
- Unmute when ready to check the result in context.
Studio Fade Out behaves more predictably with video clips
“Studio Fade Out” is a staple for podcasters and content creators. In 3.7.4, applying it at the end of a video clip no longer creates a new clip boundary. That restoration of expected behavior matters because unplanned clip splits complicate ripple edits, selection ranges, and subsequent fades. The fix keeps fades clean and clip continuity intact in timelines that include video.Waveform rendering on clipped audio
When recording too hot or importing material that’s already distorted, the waveform should tell the truth. Previous versions could render clipped audio in a way that didn’t always match the underlying samples, making it harder to spot the extent of overload. With 3.7.4, flat‑topping and overs are represented more accurately, which helps during triage—deciding whether to salvage with repair tools, clip‑gain adjustments, or re‑recording.For dialog editors and educators, this visual reliability also has a training benefit: the waveform now more consistently matches the sonic reality of clipping, reinforcing gain staging best practices.
AI‑powered effects gain clarity and reach
A dedicated OpenVINO category
Audacity has been expanding its roster of on‑device, AI‑assisted effects powered by Intel’s OpenVINO toolkit. 3.7.4 cleans up the Effects menu by moving those capabilities into a distinct OpenVINO category. The separation is more than cosmetic:- It clarifies which effects rely on AI acceleration versus classic DSP.
- It sets expectations around compute needs and potential latency.
- It helps users quickly home in on noise reduction, source separation, or enhancement tools that benefit from modern CPUs and integrated GPUs.
“Get Effects” integration
The updated “Get Effects” flow now exposes OpenVINO‑based packages, closing the gaps between discovery, installation, and first use. Rather than hunting the web or manual plug‑in folders, users can install curated effects and be confident about compatibility. For classrooms and labs, this lowers the overhead of keeping multiple machines in sync.macOS support for OpenVINO effects
A key expansion in 3.7.4 is the port of OpenVINO effects to macOS, which brings cross‑platform parity to the AI feature set. Performance will vary by hardware and the specifics of each effect, but the headline is portability: the same AI‑assisted workflows available on Windows and Linux are now within reach for macOS users without awkward workarounds. Teams that span operating systems can standardize on a common effects toolkit and share project expectations more easily.Under‑the‑hood accuracy: the Hamming window derivative
Spectral analysis and time‑frequency transforms rely on window functions like Hamming and Hann to reduce edge artifacts. In certain measurement or analysis paths, Audacity computes derivatives of these windows. 3.7.4 corrects possible inaccuracies in the Hamming window derivative, a niche change that nonetheless matters for users who:- Perform precise spectral measurements.
- Rely on derived features in plug‑ins or macros.
- Compare results across versions for research or pedagogy.
Cross‑platform housekeeping
Legacy macOS compilation fixes
Maintainers have resolved compilation issues on older macOS targets. While modern systems are the focus, many institutions and hobbyists keep capable Macs in service long after official support windows. Ensuring Audacity continues to build on these machines preserves access for recordists and editors who value stability over novelty.Universal AppImage for Linux
Linux users again benefit from a universal AppImage that aims to run on a wide range of distributions without deep dependency wrangling. For field recordists, makerspaces, or classrooms where machines may not share the same distro or package manager, a single, portable bundle simplifies deployment and rollback.How it fits into the 3.7 series
Audacity 3.7, introduced in late 2024, laid groundwork for a more responsive, modern editor. That broader release emphasized:- Improved compatibility for Linux systems.
- More legible contrast in the light theme for better accessibility.
- More robust handling of non‑standard characters when saving to cloud storage.
- Faster startup when many audio devices are present.
- More reliable importing of Opus files.
Practical testing scenarios
To get a feel for the changes, a few quick benches illustrate where 3.7.4 pays off.Auditioning filters on a muted dialog track
- Import or record a noisy dialog segment and mute the track.
- Open an EQ or noise reduction effect and press Preview.
- Adjust parameters while remaining in muted state and keep using Preview.
- Apply the effect and unmute to hear it in context.
Confirming the Studio Fade Out behavior with video
- Add a video clip with embedded audio to a project.
- Split near the end and apply Studio Fade Out to the terminal region.
- Observe clip boundaries remain as expected—no new fragment at the tail.
Inspecting clipped waveform accuracy
- Record a short passage with intentionally hot input to induce clipping.
- Toggle between waveform and spectrogram views.
- Compare the flat‑topped region and the measured peak levels against the hardware meter or a known test file.
Performance and latency expectations
While this release does not advertise sweeping engine overhauls, the crash fix around delay compensation removes a hidden performance penalty: the need to avoid certain plug‑ins during live audition for fear of instability. Users can more confidently stack:- Linear‑phase EQ on master bus auditions.
- Look‑ahead limiters for loudness checks.
- AI‑powered denoisers that introduce buffering.
Risks and trade‑offs to consider
No maintenance release is free of risk, particularly when it touches real‑time processing and clip editing logic.- Plug‑in variability: Third‑party VST/LV2/AU effects vary in how they report latency and handle state. While Audacity’s fix addresses a crash condition, some plug‑ins may still behave inconsistently when toggling latency mid‑session. Saving presets and keeping parallel tracks for destructive edits remains prudent.
- Project portability: The reorganization of OpenVINO effects and macOS availability improves parity, but project portability assumes the same effects and versions are installed. Teams should standardize effect lists and verify availability on all machines.
- Education and lab environments: The “Get Effects” integration simplifies distribution, but administrators may want to freeze versions for a semester to avoid mid‑course changes in behavior.
- Mixed media timelines: Edits involving video are inherently more complex. Though 3.7.4 patches specific failure modes, large projects with intricate splits and effects should be saved incrementally. The combination of Undo history and versioned saves remains a best practice.
Upgrade guidance for different users
Podcasters and voice editors
3.7.4 is an easy recommendation. The effect preview improvement speeds EQ and dynamics dialing, while clipped waveform accuracy helps triage guest recordings. The OpenVINO category and integrated discovery streamline setup if AI noise reduction or enhancement is part of the workflow. Upgrade between episodes, and keep the prior version’s installer around for safety.Musicians and home studios
If real‑time FX chains are central to arrangement or pre‑mix checks, the delay compensation crash fix is valuable. However, verify your favorite plug‑ins behave as expected in a scratch project before moving live sessions. Re‑scan plug‑ins after installing to ensure the new categorization doesn’t upset custom menus or macros.Educators and labs
The new welcome/what’s‑new screen can help orient students after imaging machines or installing updates. The universal AppImage is helpful for mixed Linux labs. Consider locking a lab image once validated; the 3.7.4 improvements aren’t likely to affect curriculum, but consistency has classroom value.Field recordists and journalists
Clipped waveform accuracy and stability on close turn‑arounds make 3.7.4 a pragmatic choice. If working on older macOS laptops, the compilation fixes and AI effect parity may extend the useful life of aging hardware for basic cleanup tasks.The welcome/what’s‑new screen as quiet UX glue
Many free tools rely on community documentation and forum posts to bridge the gap between versions. Audacity’s new welcome/what’s‑new screen is a gentle nudge that reduces friction after updates. It can:- Surface new behaviors (like the effect preview change) at the moment they matter.
- Point to optional components, such as AI‑powered effect packs.
- Serve as a checkpoint for first‑run audio settings, sample rate defaults, and input/output device choices.
Where AI fits without overshadowing DSP
The maturing of OpenVINO‑based effects inside Audacity speaks to a healthy balance. Classic DSP remains the backbone—fades, EQ, filters, and precise edits—while AI tools offer targeted boosts for denoising, enhancement, or separation. By demarcating the AI category and improving access through “Get Effects,” Audacity makes the choice explicit:- Use traditional, deterministic tools when precision and reproducibility are essential.
- Reach for AI effects when the problem calls for pattern‑based inference and some variability is acceptable.
Looking back to measure progress
A year ago, the 3.7 line’s promise was about smoother launches, better file import behavior, and a friendlier interface. In the months since, subsequent point releases have done the quiet work that professionals value: hardening real‑time processing, correcting measurement math, and removing thorny bugs in niche but consequential corners like video‑aware edits.3.7.4 continues that trajectory. It does not chase marquee features but removes friction where it accumulates:
- Closing a large, unsaved project is less nerve‑wracking.
- Auditioning effects no longer breaks flow if a track happens to be muted.
- Clipped material looks like clipped material, aligning eyes and ears.
- AI effects sit where they belong and are available to more users.
Sensible defaults and the path ahead
Audacity’s endurance comes from pairing sensible defaults with extensibility. The 3.7.4 release reinforces those defaults:- Accurate visuals by default, even in error states like clipping.
- Predictable edits by default, even at the ends of clips or in mixed media timelines.
- Safe sessions by default, with fewer crash traps during common operations.
- Discoverable effects by default, with a taxonomy that mirrors how people think about tools.
But those are forward‑looking wishes. Today’s 3.7.4 release meets users where they work, not where the roadmap dreams.
Bottom line
Audacity 3.7.4 is a measured, high‑value update that tightens reliability and reduces small pains across the editing day. It clears crashers tied to latency‑aware effects and complex clip operations, restores trust in waveform displays for clipped audio, and brings clarity to AI‑powered tools through better categorization and cross‑platform reach. The new welcome screen, AppImage convenience, and macOS build fixes round out a release that focuses on fundamentals over spectacle.For editors who depend on Audacity as a daily driver, that’s exactly the right kind of progress.
