Maru Sampler
FreeOne sampler, a collection of instruments. Explore sampled pianos, harps, drum kits, and percussion, then make them your own.
Plugins and audio tools
Explore what we’re building at Maru, from effects that shape your sound to visual tools that help you understand it. They give us a practical setting for developing sound, controls, and the software behind them.
Sparklizer
$39 preorderA stereo delay with reverb, saturation, and compression, developed with Jazz Calls Home from her vocal effects chain.
See your sound in motion. Inspect its spectrum, waveform, and stereo field with a transparent audio monitoring tool.
Six effects. Your order. Build a stereo chain with filters, dynamics, drive, delay, modulation, and reverb.
A rhythmic effect that lowers the sound around the kick and clap, then brings it back with the beat.
Guitarabin
$49 preorderA guitar effects chain combining compression, boost, tremolo, spring reverb, and tape delay.
Build a room around your recording. Place the sound and microphones, change its surfaces, and hear the reflections take shape.

We created our audio engine from scratch. It's fast, powerful and cross-platform.
Research through building
We’re hands-on builders exploring how academic research, emerging technology, and creative practice can work together.
Our focus is connecting these pieces into an ecosystem of musical tools. Four directions guide the work, from understanding what exists to building and testing it with others.
Map the ecosystem
We map the tools, research, and workflows of audio development to identify gaps and connections. Plugin benchmarking helps us compare approaches and understand how systems behave.
Enable other builders
We develop the Engine, SDKs, and workflows for audio builders, alongside music analysis tools for researchers exploring new ways to represent and understand music.
Build instruments and effects
We build instruments, plugins, and effects that musicians can use, with practical examples that show how research and technology work together in real musical settings.
Turn partnerships into projects
We work with artists, researchers, and audio companies on instruments, integrations, and research tools that answer real needs. These partnerships connect the lab’s work to the people who will use it.
Made with artists
We help artists express their creativity through new instruments, effects, and musical tools. As audio development becomes more accessible, we work with them to turn their sounds, ideas, and ways of making music into tools others can play.
Artist collaboration
From vocal chain to Sparklizer
An enveloping vocal effect, rebuilt session after session. We worked with Jazz Calls Home to turn her own effects chain into one expressive plugin, bringing the sound of her sessions into other musicians’ hands.
Have a musical process you’d like to explore with us?
It might be an effects chain, a playing technique, or a collection of sounds. Tell us how you work and what you would like to make.
Maru Engine
Audio toolkit for the intelligence era
We built Maru Engine to connect the pieces of audio development and make multi-platform module authoring faster and more robust. The goal is simple: tools that sound great, look good, and work across browsers, DAWs, and hardware.
TypeScript SDKs, reusable audio components, a modern UI kit, and working examples bring sound, graphics, and deployment into one workflow.
Audio SDK and AI building blocks
Compose instruments, effects, and MIDI tools from reusable DSP components. Connect models and services through shared APIs.
A modern UI kit
Build expressive interfaces with ready-made controls, meters, visualizers, and layouts. Develop the interaction alongside the sound.
Connected runtimes
Bring sound, controls, and presets from the same project into browsers, native plugins, and hardware.
Working examples and release tools
Start from playable instruments and effects, inspect how they work, and use shared tools to compile, test, and package your own.
What you can build with
- Composable instruments, effects, and MIDI tools.
- Modern interfaces and audio controls.
- AI models connected to musical tools.
- Workflows for developers and coding agents.
- Working examples with inspectable source.
- Build, test, and package your audio tools.
Developing tools others can build on
We’re interested in working with developers, researchers, and audio teams on shared tools and open-source projects. Some work is still being prepared for public release; access and licensing are described for each project.
Discuss a technical collaborationMaru Studio
Build with agents
Create instruments, sampler banks, and effects with a coding agent. Connect modules and play the result in your browser. No development setup or coding required.
Describe the sound and controls you want. The agent builds with Engine components, and you play, listen, and refine.
Describe your idea
Tell the agent what you want to make: an instrument, a sampler bank, an effects chain, or a new way to connect modules. Start from an example or explore something of your own.
See and hear it in the browser
Play your creation in the browser as it takes shape. Try the controls, listen to the result, and ask the agent to refine the sound and interface.
Export, use, and share
Bring your tool into your music-making setup, share it with others, or prepare a release to sell. Our team helps you prepare and test plugin downloads.
Studio is in early preview. We’re looking for experienced and aspiring plugin developers to try it, explore what they can make, and help shape the workflow. Get in touch.
