Interactive Space Radio Explorer

Expanding Sonic Universe is a tool for exploring radio-wave-emitting objects in space.

Using a mobile device and headphones, the work allows visitors to listen to ten active galaxies in deep space at their real-time positions in the sky. The objects can be discovered by pointing the device around you and following their sounds. The sonification of these quasars and blazars is based on decades of research data from Aalto University’s Metsähovi Radio Observatory (MRO), documenting variations in the brightness of these distant objects.

I led the development of the application, including its functionality and visual layout. It’s easy to assume that AI produces the best and most practical code, but that’s not the default case. The application required several rounds of testing to accommodate a wide range of modern mobile devices. For example, the initial methods proposed by the coding tool for handling device orientation proved insufficient.

Echotect — Turn your hood into a delay

I created the open source application Echotect, which allows you to turn your hood into a delay. It can also be used as an acoustic lab on some level. Add reflection points, structures, and use included global building data for automatic echo field mapping.

https://janne-s.github.io/Echotect/

The project can be exported as impulse response files to the reverb you use and the like; as stems of the echo field, and as the entire wet track. A Max4Live device is included, where you can import the echo field manifest in JSON format. You can also import the same JSON into your own applications.

It is possible to import an image into Echotect: a set design image, maybe a historical map or just a cool image that you want to match echo points to. There’s a scale tool to calibrate the image to real world measurements.

The Max4Live device is by default four-channel to implement surround sound if necessary, but go wild with it.

I personally like listening to sound from somewhere further away and finding interesting perspectives for music mixing and the like. The app basically allows IR file creation from any location, which I’d imagine could have uses in movie sound design.

The app is not designed to be a hard core acoustic simulator, but it goes a long way there. Reflections have reflections and they are affected by real world occlusions and other freely adjustable parameters. Deeper echo fields are best created in the render mode.

GeoBuzz — A Spatial Music and Sound Composition Tool

The listener is the playhead

GeoBuzz is an open‑source web tool for creating spatial, walkable music — musical pieces and audio experiences that are shaped by geography and movement rather than by traditional timelines. Instead of arranging notes on a grid, you place sounds, synthesizers, sequencers, and modulation elements directly on a map. As a listener walks through that map, the sounds change based on position, direction, and speed.

At its core, GeoBuzz consists of two parts: the Editor, where you design your soundscape, and a lightweight runtime engine that plays back the composition in a web environment or in an application. You can define control zones, movement paths, automation curves and distance‑based sequencers — all tied to physical space — and export your work as a standalone package for further development.

Spatial music like this builds on ideas from electroacoustic and location‑based sound practice, where the position and movement of sound sources in physical or virtual space become part of the composition itself. This is related to the broader concept of spatial music, where sound localization and placement are intentional compositional tools.

Using GeoBuzz doesn’t require specialized hardware. It runs in modern browsers and takes advantage of geolocation and orientation features when available. The focus is on experimentation: you can test ideas in the editor, simulate movement, and iterate without complex setup.

The tool is developed with open technologies like Tone.js for audio and Leaflet for map handling. Community contributions, examples, and documentation help other creators understand how the system works and how to integrate it into their own projects.

GeoBuzz is not just software — it’s also an invitation to think about music and sound in relation to place and movement. Compositions made with it can be experienced by walking through space or by interacting with the exported audio application in a way that ties listening to environment and motion.

See it in action: github.com/janne-s/GeoBuzz

The project supports a developing field of composers, developers, and sound artists working with spatial form as a shared medium. Your support sustains development and contributes to the continued emergence of spatial music as a distinct creative genre. Buy me a coffee?

Sound Index: Organize Ableton and Logic Pro Samples

If you’ve been producing for a while, your sample library is probably a mess. Projects scatter the same sounds across folders, and it’s hard to remember which kicks, snares, or loops you’ve actually used and which ones are just wasting disk space.

Sound Index solves that problem. It’s a lightweight macOS tool that scans your Ableton Live set files (.als), Logic Pro (.logic, .logicx) project bundles, and builds a searchable database of every sample reference. Each audio file in Finder gets a comment showing how many projects it appears in and which ones. The original samples aren’t modified – just annotated with metadata you can use.

The result is a practical way to:

  • Audit your sample usage
    Instantly see which sounds are indispensable and which are never touched.

  • Clean your library
    Identify duplicates and unused files without breaking projects.

  • Search efficiently
    Run queries on a real database instead of digging through folders by hand.

Sound Index is a transparent solution built around open formats (Finder comments + SQLite) so you’re not locked in. If you’re tired of losing track of where your sounds live or which projects depend on them, this is a simple but powerful fix.
