Audacity 4 is missing lots of Audacity 3 features – I added them
Audacity 4 is a ground-up rebuild, and rebuilds leave things behind. Here is the full accounting of what Audacity 3 could do that Audacity 4 cannot, checked against the source of both.

Moin. I worked on Audacity 4, which just released. If you’re coming from Audacity 3, you’ll see that it looks a lot better now, and has some really handy new UX which you can learn more about in the release video. However, you’ll also soon see that it is a bit… unfinished. Several effects and other functions are missing, including some vital ones like exporting stems and Mix & Render. Why the decision was made to release like this I do not know as I left the team in late 2025, but if I had to guess (and this is really just a guess) it’s probably just time pressure from the corporate overlords who probably demanded this release – no matter what’s in it! – to be out by a certain date. So this version, even though it says 4.0 is perhaps more akin to a Beta 5, with the actual complete 4.0 bearing the name 4.1.
Anyway: In the lead-up to the release I played around with LLMs a bunch and made some creator tools, and eventually asked myself the question: But can I make a web version of it? And I could. Behold: Soundscaper, a web-based audio editor that incorporates practically all features of Audacity 4. And while I was at it, I also added a bunch of Audacity 3 features to it. So feast your eyes upon the following table, with the many features that you can use in Soundscaper.
You’re not even locked into using only Soundscaper, Soundscaper can import and export AUP4 files, so you can switch between the two. This comes especially handy on mobile because – yes, Soundscaper, as a web app, runs anywhere a browser does. So while you can’t use Audacity 4 on your phone, you can start recording and editing in Soundscaper, and then export the AUP4 to continue editing on your desktop later. Or just open it back up in Soundscaper again!
Soundscaper is free and open source, and completely private – despite being a web app, there’s no account and all files stay on your device.
Audacity 3 vs Audacity 4 vs Soundscaper
(note: This very much is a “negative” list which only lists out the stuff that’s missing in Audacity 4. It’s not to be taken to mean that Audacity is only missing features, because it does have a lot still)

My focus hasn’t just been copying Audacity 4. I also have added tons of new features, such as:
- Video tracks
- Track routing (including send/group buses)
- Project bin
- Automation
- Surround support
- Expanded format support
and much, much more, which you can read more about in the Soundscaper docs. I even started working on an entire video editor, which I call Framescaper (though that one I haven’t paid nearly as much attention to. Yet.)
I hope you enjoy Audacity 4 and Soundscaper!
