Where Is Martin Hairer’s Compression Software? The Complete 2026 Answer
If you searched where is martin hairer’s compression software, you’re probably stuck between two very different stories that got tangled together on the internet. One story is about a Fields Medal-winning mathematician. The other is about a small Mac audio company. Most articles blur the two together and never actually answer the question. This one does.
Short answer: Martin Hairer’s software is called Amadeus Pro (and its lighter sibling, Amadeus Lite), made under his company HairerSoft, and it’s available directly at hairersoft.com or through the Mac App Store for $59.99. But that’s only half the answer, because “compression” means two completely different things depending on which Martin Hairer topic you actually landed here from. Let’s untangle both.
Why This Question Confuses So Many People
When someone types where is martin hairer’s compression software into Google, they’re usually coming from one of two directions:
- They read about Hairer winning the 2014 Fields Medal for his work on stochastic partial differential equations (SPDEs), saw a news article mention that “compression techniques” and “wavelets” inspired his theory, and assumed there’s a piece of math software tied to that theory.
- They already use, or heard about, Amadeus Pro, his audio editing app, and are looking for the “compressor” tool inside it — the dynamics-processing feature that controls volume levels in a recording.
Almost every article ranking for where is martin hairer’s compression software picks one of these threads and ignores the other, which leaves half of all searchers with no real answer. So here’s both, side by side.
Who Is Martin Hairer, Actually
Martin Hairer is a mathematician and, less commonly known, an independent Mac software developer. He’s a professor who won the Fields Medal in 2014 for developing a theory of “regularity structures” that made sense of previously unsolvable stochastic equations. But outside of academic mathematics, he’s spent decades building and maintaining audio software under the name HairerSoft.
This dual identity is the entire reason people keep asking where is martin hairer’s compression software — because his math achievement and his software product both involve the word “compression,” just in completely unrelated senses. how does version control software like git work?
The Math Side: What “Compression” Meant in His Fields Medal Work
According to Quanta Magazine’s profile of Hairer, his breakthrough idea came to him while walking back to his office at the University of Warwick, when he realized he could tame unruly mathematical distributions using an approach modeled on “wavelets” — brief, heartbeatlike oscillations that encode information in JPEG and MP3 files. He’d previously explored using wavelets for a function inside his own audio software.
The key mathematical property he borrowed: any wavelet can be reconstructed by adding together a finite series of identical wavelets squashed to fractions of its initial width — a half, then a fourth, then an eighth, and so on. That self-similar, fractional-scaling idea — the backbone of wavelet-based data compression — is what he adapted into a tool for solving SPDEs.
So when people ask where is martin hairer’s compression software expecting a math tool, there isn’t one. Wavelet compression here is a concept he borrowed from signal processing, not a program he released. There’s no downloadable “Hairer compression algorithm” for JPEG or MP3 files — he didn’t invent JPEG or MP3 compression, he used the mathematical logic behind it as inspiration for pure math.
One clarification worth noting directly: on the HairerSoft forum, Hairer himself corrected a common misquote from that era, pointing out that JPEG2000 does use wavelets, but MP3 does not, and that the confusion likely came from him mentioning both image and sound compression to a journalist who mixed the two together. That single mixed-up detail is part of why so much confusion still surrounds this topic today.
The Software Side: Amadeus Pro and Where to Actually Find It
Here’s the part most competing articles skip entirely, and it’s the part actual searchers usually want.
What Amadeus Pro Is
Amadeus Pro is a full multi-track audio editor built for macOS. It’s used for recording, editing, cleaning up, and converting audio files. The Apple App Store listing describes it as software for live audio recording, creating iPhone ringtones, digitizing tapes and records, converting between sound formats such as MP3, AAC, AIFF, WAVE, WMA, CAF, FLAC, and Ogg Vorbis, remastering an iTunes library, and recording internet streams. It also supports non-destructive editing and can be extended with Audio Units plugins.

If someone still asks where is martin hairer’s compression software after reading this table, the direct answer doesn’t change: hairersoft.com is the source, and the Mac App Store is the alternate, verified channel.
Amadeus Lite vs. Amadeus Pro
HairerSoft’s own site lays out the lineup plainly: Amadeus Lite is described as an intuitive wave editor supporting formats like AIFF, WAVE, MP3, WMA, AAC, Ogg Vorbis, and Apple Lossless, while Amadeus Pro is the more powerful multitrack editor supporting the same range of formats plus additional professional features.
- Amadeus Lite — single-track editing, simpler interface, lower cost, good for basic cleanup and format conversion
- Amadeus Pro — multi-track recording and editing, Audio Units plugin hosting, batch processing, spectral analysis tools
The Actual “Compressor” Tool Inside the Software
This is the second meaning of “compression” tangled into this keyword, and it’s a real, practical feature — not a math concept.
Amadeus Pro supports Audio Units (AU) plugins, including Apple’s built-in AUDynamicsProcessor, which functions as a compressor/limiter for controlling volume dynamics in a recording. This is the tool audio editors use to even out loud and quiet sections, not anything related to file-size compression or Hairer’s academic work.
A long-running thread on the HairerSoft forum makes clear this has confused users for years. One user asked directly whether Amadeus Pro even includes a compressor, noting after downloading the English version, there didn’t appear to be a compressor bundled with Amadeus Pro, and asking whether one existed under a different name. Another thread shows a user struggling with Apple’s version of this tool, describing how they wanted no gate, no lower threshold, a compression ratio of 3:1, and a peak limiter at -6db, but found Apple’s AUDynamicsProcessor interface — an X-Y graph rather than simple sliders — confusing to work with. The practical fix, given in that same thread, is to switch to the generic Audio Unit interface in Preferences to get numeric sliders back instead of the graph view.
How to Find the Compressor in Amadeus Pro
- Open your track in Amadeus Pro
- Go to the Audio Units/effects menu and select Apple’s AUDynamicsProcessor
- If the graph-style interface is confusing, go to Preferences → Advanced and enable the generic user interface for Audio Units
- Adjust threshold, ratio, and gain using the now-visible sliders instead of the X-Y graph
- Preview in real time before applying
HairerSoft: The Company Behind the Software
HairerSoft isn’t a large studio — it’s essentially a small, long-running independent operation, with Martin Hairer himself frequently responding directly to users on the support forum, moderating threads, and signing off replies as “Martin — HairerSoft.” That’s part of why searchers asking where is martin hairer’s compression software sometimes land on informal forum threads instead of a polished company page: support is handled personally, not through a large customer service team.
Reputation and Longevity
Reviewers who’ve used the software for years describe it favorably. A KVR Audio review calls it solid, stable, flexible, and sold at an insanely cheap price for what it can do, while another user on the same platform describes Amadeus Pro as “the Swiss army knife of sound editing,” useful for broadcasting, podcasting, beat splicing, sample management, and track cleaning.
An older but useful review from TidBITS put it this way: Amadeus is a sound file editor that’s been in continuous use for over six years, remaining firmly and indispensably central to the reviewer’s sound-processing work — a rare case of long-term software loyalty in a category where programs usually get abandoned.

Why This Matters Beyond Just “Downloading Something”
Anyone still wondering where is martin hairer’s compression software after digging through scattered forum posts and old tech blogs has run into the same wall: nobody drew a clean line between the math story and the software story. The math side is fascinating on its own — a working mathematician noticing that the same fractional, self-similar structure behind JPEG and MP3 compression could tame equations that otherwise read as “infinity equals infinity.” The software side is much more ordinary and much more useful day-to-day: a genuinely well-built, affordably priced Mac audio editor that’s been actively maintained for two decades, with a dynamics compressor tool that works exactly like any other DAW’s compressor once you know where to look.
Both are legitimately “Martin Hairer’s compression” — just not the same thing, and not something either one has to compete with the other to explain.
Frequently Asked Questions
Is Martin Hairer’s compression software the same as JPEG compression?
No. JPEG and MP3 use wavelet-based compression that inspired his math theory, but Hairer didn’t create or sell any file-compression software — his own software (Amadeus Pro) is an audio editor, not a compression tool for files.
Where can I actually download Amadeus Pro?
Directly from hairersoft.com or through the Mac App Store, both listing it at $59.99.
Does Amadeus Pro have a compressor built in?
It hosts Apple’s AUDynamicsProcessor Audio Unit for dynamics compression rather than including a separate proprietary compressor by default.
Is HairerSoft still active in 2026?
Yes — the HairerSoft website and Amadeus Pro’s App Store listing both show current copyright and update activity through 2026.
Is Amadeus Pro only for Mac?
Yes, it requires macOS 10.13 or later and has no native Windows version, though some third-party download aggregators list it under Windows sections inaccurately.
What’s the difference between Amadeus Lite and Amadeus Pro?
Amadeus Lite is a simpler, single-track wave editor, while Amadeus Pro adds multi-track recording, plugin hosting, and more advanced editing tools.
Why does Apple’s compressor interface look different from other software?
Apple’s AUDynamicsProcessor uses an X-Y graph interface by default instead of numeric sliders, which can be switched to a generic slider-based view in Amadeus Pro’s Advanced preferences.
