Speed up development
Developing great audio DSP algorithms is notoriously hard. It requires not only extensive mathematical and coding skills, but also deep knowledge in a wide range of fields such as signal processing, electronics, and psychoacoustics, as well as familiarity with domain-specific issues and techniques.
Putting everything together often takes much more effort than expected. Those algorithms then also need to be optimized, tested, debugged, and potentially adapted to specific target platforms, which further inflates allocated time and costs.
We've been doing all this for years and, despite our excellent track record in taking the pain away from our customers, we've grown tired of those hardships too. That's why we chose to develop and offer you an ever-expanding catalog of reusable and adaptable algorithms to speed up the most time-consuming parts of audio programming and save you and us time and money.
As far as the effectiveness of this approach goes, the numbers speak for themselves:
less DSP code
in all projects so far

Indeed, our algorithms are designed so that programming audio engines mostly reduces to defining modules, interconnections, and parameter mappings, leading to a workflow that conceptually resembles visual programming languages and modular synthesizers.
Furthremore, they are designed to maximize
- ease of use: their APIs are simple, minimal, and boringly consistent, so that there is very little to learn and developers can get productive in no time;
- ease of integation: they stick religiously to non-opinionated design principles and are provided as simple header files, thus allowing for high interoperability and never getting in your way; and
- code correctness: they fully implement contract programming, allowing to catch bugs much earlier and thus reducing total development time even further.
Use everywhere
Unlike many libraries and frameworks that are based on the latest shiny tools or rely on platform-specific features, we chose to rather have our algorithms
- stick to time-proven, ubiquitous, least common denominator technology (plain C99 with no external dependencies, not even the C standard library); and
- packaged in the most neutral and easy-to-integrate way possible (single independent headers only defining static variables and functions).
This means that they are completely platform-agnostic and run unmodified on all today's platforms, ranging from cheap MCUs to web pages, including mobile and desktop.
We regularly test them on:
Daisy Seed
(STM32, ARM Cortex M7)
Android and iOS
Windows, macOS, and Linux
(x64 and Apple Silicon)
Chrome, Edge, Firefox, and Safari
(WebAssembly via Clang, w/o Emscripten)
Optional C++ wrappers are however also provided for your convenience.
Use anytime
Relying on small technology suppliers and signing deals with them, no matter how good they and their products/services are, is complicated and risky. We get that. That's why we propose a liberal licensing model that makes it really easy and convenient to conduct business with us.
Our proprietary license, which is applicable to all our algorithms, has the following main characteristics.
- It is unlimited: you are allowed to use our algorithms ad libitum in your products, with no limits on their number and type, number of developers involved, time, or territory.
- You are allowed to make and own your changes and also keep them for youself.
- It spares you from vendor lock-in to the greatest possible extent we can support: you are normally allowed to have third parties work with/on our code, as long as we keep track of them and — to put it informally — they have not caused us trouble in the past. Should our company run out of business, you can keep using and working with our code, so that our technology can safely outlast us.
- Multiple confindentiality options are available: we can settle for keeping our contractual relationship fully confidential, or make it public after your product is released, or also make it public past a certain time, as long as conditions are the same for both parties.
- Payments are one-off and upfront and there are no hidden or recurrent costs of any kind. Unlimited bug fixing is also included. Other forms of support are not, though, but we'll try to be as nice as possible.
For the most basic algorithms we also offer the option to use the GPLv3, so that free software/open source projects can use them without even having to ask.
So, to sum up:
Open source license
- Free as in speech and beer
- Any number of developers
- No time limits
- No lock-in
- Only applicable to some algorithms
- Only for GPLv3-compatible projects
- No confidentiality
- You must share your changes
Proprietary license
- One-off payment, no hidden costs
- Any number of developers
- No time limits
- No lock-in
- Applicable to all algorithms
- Any product, any number of products
- Multiple confidentiality options
- You can keep your changes
Documentation
All our algorithms come with full technical documentation describing their purpose and usage, as well as essential technical background information, including common API usage rules.
Support
Our primary mission is assisting customers in creating and improving their own products.
We would be more than happy to help you, whether it is about a simple doubt clarification all the way up to designing and implementing new custom audio engines from scratch.
Collections and bundles
Brickworks is our basic audio DSP toolkit that supplies you with the fundamental building blocks for creating and enhancing audio engines on any platform.
It consists of over 50 algorithms and is licensed as a whole, either under the GPLv3, free of charge, for free software/open source projects or under our liberal proprietary license, for just 3,000 € one-off.
It is fit for creating convincing equalizers, filters, compressors, guitar/bass multi-effect processors, subtractive synthesizers, and more.
Don't you believe it? Here are two examples created using only Brickworks algorithms and a cheap electric guitar.

Brickworks Pro takes you to the next level.
This is an ever-expanding collection of state-of-the-art-or-beyond algorithms with advanced features for the most demanding applications. They can get you significant audio quality improvements even if you only strategically use them in critical parts of your audio engines, thus helping you position your products in the high-end of the market.
Given their high value, these algorithms are normally priced and licensed individually under our liberal proprietary license.
