About — Joel Löf, Audio Software Developer
The short version
Section titled “The short version”Custom audio software — for the web, desktop, and mobile. If your project involves real-time audio, DSP, plugins, or browser-based audio tools, you’re in the right place.
The rare intersection of audio domain expertise and modern software engineering. Most audio developers stay in C++. Most web developers don’t understand audio. This practice bridges both worlds — fewer handoffs, faster iteration, and better results.

Background
Section titled “Background”The path to audio software has been hands-on from the start:
| Period | Role | Key takeaway |
|---|---|---|
| 2010–2011 | Music teacher | How musicians think and what tools they need |
| 2011–2014 | Audio engineering degree (LTU) | Signal processing, acoustics, studio engineering |
| 2014–2019 | Touring playback tech & freelancer | Live audio under pressure — international tours across Europe and America |
| 2016–2017 | Theatre sound (Göta Lejon) | Wireless systems, complex production audio |
| 2019–2021 | Broadcast engineer (Swedish Radio) | Live radio, codec optimisation, SIP-based remote audio |
| 2021–present | Audio software developer (Evolution) | Game audio middleware, real-time DSP, TypeScript/Rust/C++ |
This journey covers audio from every angle — the musician’s perspective, the live engineer’s constraints, the broadcaster’s requirements, and the software developer’s architecture.
