Hello everyone,
Together with my colleague Olmo, I've been working on something different:
Fourier, a spectral audio editor for Apple Silicon Macs. We're now looking for people who'd be interested in trying it out and giving us their honest feedback.
There were a few reasons this project mattered to me. There are plenty of openly available, state-of-the-art audio models and algorithms out there, yet a lot of companies charge a hefty price for solutions that can, in many cases, be reproduced in a Colab notebook or with a handful of Python scripts.
So the idea was simple: bring those models together inside a complete, feature-rich audio editor that anyone can actually use, while taking full advantage of the compute power of the new Apple Silicon chips (M1 through M5). Because the whole editor is GPU-accelerated, the experience stays fast and fluid, unlike a lot of other software that unfortunately still relies on interfaces and frameworks (often QT) designed many years ago.
For now, Fourier runs only on macOS 14–15 and on Apple Silicon, but down the road we may look into a way to bring it to Windows too.
The editor is essentially complete. Some highlights:
- 45+ modules covering a wide range of audio correction and restoration tasks.
- A text mode that transcribes speech in virtually any language, lets you edit the transcript as easily as a Word document, and then regenerates the audio in the same voice seamlessly.
- A pitch-correction system whose quality has little to envy from far more expensive software.
- A modular architecture we plan to keep expanding with new features and modules over time.
Honestly, I think it's one of the best audio editors on the market right now, though, being a brand-new product with a feature list that already rivals tools that have been around for years, there may still be a few small things to polish here and there. As it stands, it's an extremely fast, feature-packed editor that puts advanced generative and restoration tools, the kind usually reserved for developers or locked behind subscriptions, directly in your hands. And crucially, all processing happens locally, entirely on your machine.
We're looking for people who'd like to try Fourier (in exchange for a complete copy of the software) and share feedback, or even suggestions, so we can keep improving it and deliver a better and better piece of software.
Fourier will go on sale very soon (somewhere between $100 and $150), with regular updates planned. So if anyone would like a copy in exchange for a bit of feedback, I'd love to hear from you.
Requirements
- Apple Silicon Mac (M1–M5)
- macOS Sonoma (14) or later, up to Tahoe
- At least 16 GB of RAM (more RAM makes running some of the heavier models easier)
---
- Platform: Native macOS app, built exclusively for Apple Silicon (M1–M5). Not a cross-platform wrapper — written in Swift with a modern SwiftUI/AppKit interface.
- Processing: 100% on-device. Nothing is uploaded to the cloud; all analysis, restoration, and AI generation run locally, GPU/Neural-Engine accelerated via Metal and Core ML.
- Editing core: Full waveform + spectrogram editing, spectral repair (heal / attenuate / boost), and time-frequency selection tools.
- Restoration suite: De-hum, de-click, de-clip, de-ess, de-reverb, broadband denoise, and more.
- AI suite (all local): Speech transcription (any language), voice re-generation from edited text, note/pitch detection and correction, source separation, and generative audio.
- Mastering & stereo: Reference match, stereo width control, mono↔stereo, and related tools.
- Architecture: Modular — new modules and features are added on a rolling basis.
- System requirements: Apple Silicon Mac, macOS 14+ (Sonoma → Tahoe), 16 GB RAM minimum.
