About the Project

The mission, technology, and people behind Aumixys.

Laboratory precision, zero compromises.

At the heart of Aumixys aren't standard browser libraries, but a proprietary DSP engine built with WebAssembly (Wasm) technology. By compiling Faust code directly into binary processor instructions, we offer measurement precision and dynamics previously reserved for desktop DAW applications. This is an engineering tool you can trust before sending your master for distribution.

🌈 Spectral Analysis (CQT)

Instead of classic FFT, we use Constant-Q Transform (CQT). This allows for logarithmic frequency distribution (48 bins per octave), perfectly mapping human hearing perception and enabling precise sub-bass and harmonic analysis.

📏 EBU R128 Standards

Loudness calculations (LUFS) and True Peak detection (oversampling) comply with international broadcasting standards, ensuring full compatibility with Spotify, YouTube, and Apple Music algorithms.

🔒 Security & Performance

All processing happens locally on your device. Your audio files never leave the browser, and the engine utilizes full CPU power through multi-threading and AudioWorklet technology.

⚡ 64-bit DSP Engine

The DSP engine operates with 64-bit floating-point precision, compliant with ITU-R BS.1770-4 standard. This ensures laboratory-grade loudness measurement accuracy (LUFS) with error margins below 0.1 dB, which is crucial for professional mastering.

Behind the Code

Jacek Wiśniewski (SOUNDSAAR)

"I created Aumixys because I needed a precise QC tool for my masters that didn't require installation on every computer I work on. As a mastering engineer and developer, I merged these two worlds to give creators the confidence that their music will sound exactly as planned — on any playback system."

From Amiga Trackers to Precision DSP

Meet the Creator of Aumixys

My audio journey began in 1990 with the Commodore Amiga 500. It was there, creating my first compositions, that I learned that in music, every detail matters and creative approaches to technical limitations are key. Over more than 30 years, I've traveled the path from 8-bit trackers, through the era of early Cubase and WaveLab versions (1996), to modern production under the Anthares and Soundsaar banners.

As a musician, sound engineer, and mastering engineer with extensive experience, I've repeatedly faced the same problem: how to objectively assess mix quality before publication?

Aumixys isn't another corporate product. It's a tool built by a practitioner for practitioners. I've combined my 30 years of studio experience with modern WebAssembly technology and a proprietary DSP engine to give you the precision I've been searching for all these years.

🎵 1990: The Beginning

Commodore Amiga 500, trackers, 4 channels, 8-bit samples. The struggle for every decibel and dynamic range in a world of limited resources.

🎛️ 1996: Professional Era

First versions of Cubase and WaveLab. Transition from trackers to DAW and the beginnings of professional mastering.

🔬 2020+: New DSP Era

Combining 30 years of experience with modern WebAssembly technology and Faust DSP.

"Someone who started on Amigas in 1990 understands the struggle for every decibel, for dynamics, and for sonic purity much better than those raised on the infinite tracks of modern DAWs. This is an incredible story that gives you something you can't buy: historical and technical context."

Advanced DSP Engine & Industry Standards

Aumixys is built on a proprietary DSP engine that combines laboratory precision with modern web technology. Here are the key elements of our technical architecture:

⚙️ WebAssembly (Wasm) Engine

All audio processing happens in the browser through Faust code compilation to native processor instructions. WebAssembly provides near-desktop application performance, enabling real-time analysis without sending data to the server.

🎛️ Faust DSP Framework

We use Faust – a functional programming language for audio signal processing. This allows for creating DSP algorithms with deterministic precision, identical across all hardware platforms.

📊 EBU R128 & ITU-R BS.1770

Full compliance with international loudness standards. LUFS (Loudness Units Full Scale) and True Peak algorithms meet the requirements of streaming platforms: Spotify, Apple Music, YouTube, and Tidal.

🔬 64-bit Calculation Precision

All calculations are performed with 64-bit floating-point precision, eliminating rounding errors and ensuring numerical stability even with extreme dynamic range values.

🎯 AudioWorklet & Multithreading

We use AudioWorklet API to isolate audio processing from the main rendering thread, ensuring interface smoothness even during intensive DSP calculations.

🛡️ Data Security

Zero audio file uploads to the server. All processing happens locally in the browser, with files analyzed in RAM without disk storage.
