Ready for iOS 27, I’ve released the Ferrite 3.3 update. Includes significant speed boosts when exporting CAF or M4A files. Also released? Hokusai 3 and Hokusai for Mac! Huge update/new app! And have I mentioned how much I like Liquid Glass in the 27 OSen?

A USB Audio Device is connected, with 8 channels, each with their own VU meter arranged around the record button, which softly reflects their green bars. They also have dotted lines indicating the recent peak audio level.Below, the Headphone Monitoring menu button, the Input Gain dial, and the Normalise Recording switch.

After more than 6 weeks, Apple have finally(!) fixed the issue preventing me from upload a TestFlight build of Hokusai for Mac. 🎉 Submitted, pending approval. If you haven't jumped on the TestFlight yet, now's a great time to do so!

Today, I want to pull back the curtain on Hokusai 3 — going into TestFlight beta testing soon, I'm looking for plenty of people to kick the tyres. Rewritten from the ground up, with a beautiful, colourful new design and a _whole bunch_ of the most requested features!

About 15 years ago (summer 2011) we released Hokusai Audio Editor. It looked like this — before Retina, when the only screen sizes were “iPhone” or “iPad” and you had to design each in a separate file:

It’s now been 1 month(!) (almost to the minute!) since I filed an Apple Developer Support request for them to make the change necessary to upload macOS builds of the thing I want to announce. Still waiting. I think that, tomorrow, I'll just go ahead (iOS only) & hope they get their act together soon

So here's a fun fact — and by “fun” I mean “weird and annoying”: If you made an iOS app so long ago it was before the Mac App Store existed, then go to add a Mac version now, the App Store throws it back in your face when you try to upload it.

About to upload (beta test) builds of something I've been working on for well over 2 years. Feels strange, like I must've forgotten _something_, but everything seems to check out…

I’m sure I’m just showing my age here, but I still like the magic of adding cloud sync to an app and watching stuff flow seamlessly between devices. Networking was always a big deal to me even back when it was just a serial cable between two machines.

iOS 26 Liquid Glass + SwiftUI thing I recently discovered: If you're using `glassEffect(in:)` with a custom Shape, and you're using "interactive" glass, it'll render the interaction highlight as a capsule, _not_ your custom shape. This will often look bad because of the mismatch, esp. at corners.

Exactly 10 years ago today, Ferrite 1.0 was released to the App Store! It's been a pretty wild decade. Here's to 10 years of Ferrite, and many more to come…

Ferrite 3.2.1 is out today, with support for high-quality recording from AirPods (with H2 chip: AirPods 4, AirPods Pro 2 or 3)! apps.apple.com/app/id101878... Note: this requires iOS 26, and you’ll need to enable the feature in Ferrite, Tools → Settings → Recording. Why? Well, an iOS 26 bug…

And finally, there's one more thing I hope to be able to announce soon:

Some bad news regarding our synthesisers: I think this is the year we'll have to retire these, probably this month. Shame, as I love them, but they've had a good run (the "new" one is over 10 years old!) and predate all sorts of modern development tech like Swift, SwiftUI, and AUv3.

Next, Transcriptionist: • Background transcription — won't be as widely available, as transcription needs GPU & fewer devices support background GPU use • Exploring use of Apple's transcription API. Preliminary tests seem promising — not as accurate as existing large brains, but quick and efficient…

First up, Ferrite: • Continue exports in background, track progress in a Live Activity (note: it'll still be possible for exports to get cancelled if other apps require too many resources) • Lightly updating UI for Liquid Glass. Don't expect complete rethink — that's not something to rush into.

I thought I'd take a moment to provide a sort of mini-roadmap for Wooji Juice's autumn app updates. Note that iOS 26, macOS 26 and iPad OS 26 are all kinda “coming in hot”, so, don't take _any_ of this as promises, it'll depend on the state of the OSen. But these are our plans…

I've been doing a lot of stuff recently with the new iPad OS 26 menu system. Something I think Apple haven't thought through — I haven't seen any guidance from them on it & their apps seem to be ignoring it — is: an iPad app that edits documents, also kinda has 90% of the Files app shoved in to it.

Looking for TestFlight beta testers for Hokusai Audio Editor! My first audio editing app, it came out long before Ferrite (in 2011!) and is still going strong: www.wooji-juice.com/products/hok... — I have Big Plans for its future, and (according to the App Store) it’s used a lot more than Ferrite…

Ran into a weird word-wrap issue in something I’m working on in SwiftUI. Was it a problem with my text rendering? My Markdown parsing? A bug in SwiftUI? Nope! Turns out, I stumbled on a glitch somewhere in Cocoa’s text engine — plain old TextEdit has exactly the same weird behaviour:

A screenshot of macOS TextEdit, with some text typed in to it. First, some commentary reads “Why does the list of file extensions word-wrap weirdly? They have spaces between them — standard ones, not   or anything:”. Then, an example paragraph which reads “Audio can be stored in different formats, each with their own strengths and weaknesses. Hokusai can import audio in many of the common ones so you can use them in your projects: .wav, .mp3, .m4a, .flac, .caf and many more.”. This paragraph is strangely word-wrapped, where the line breaks with plenty of space left. Then, more commentary: “Adding extra spaces, or en- or em-spaces, doesn’t help either. But if you manually insert “zero width space” (Unicode U+200B) between them, it works as expected:”. Finally, a second copy of the example paragraph, this time correctly wrapped.

Apple journalist of almost two decades here: Don't do this. First and most importantly, the setting shown in the post below does NOT disable Apple Intelligence features—it turns off the *report of queries Apple Intelligence is making on your behalf*, provided so you can audit what it's doing. 1/3

Now I can actually post here, I can put up a link to Monday's article about using #SwiftLang async/await with #SwiftUI alerts: www.wooji-juice.com/blog/stupid-...

Transcriptionist 1.7 is now out and trundling through the App Store's various servers. On iOS/iPad OS 18, you'll see a new style of document browser, with a “title banner”. Tip: Settings, User Guide etc are now reached from that banner — if you don't see it, swipe down to show it.

Finally Bluesky was able to verify that we do, in fact, exist, and can now actually post — so we can get this thing started!
