What We Do

At Colahall, we design and build hardware, software, and firmware that empower creators, developers, and audio professionals to shape sound greater openness and transparency. From the physics of sound to high-level software architecture, we approach audio as both an art and a science.

Embedded Audio Systems

We design and prototype embedded audio hardware and develop software that integrates seamlessly into your products. From microphone arrays to custom driver-level processing, we deliver optimized solutions for real-time performance and integration.

We offer support with:

• Audio hardware prototyping

• Custom drivers and firmware integration

• Embedded Linux (Yocto, Buildroot)

• Embedded platforms: ESP32, Raspberry Pi, Arduino, and more

Real-Time DSP Software

We develop high-performance audio processing software optimized for real-time responsiveness on modern CPUs and microcontrollers.

We specialize in:

• FIR/IIR filters, beamforming, and spectral audio analysis

• Audio plugins (AU, LV2, VST3)

• SIMD acceleration and fixed-point DSP optimization

• Cross-platform DSP frameworks in modern C++

Creative & Strategic Collaboration

Whether you’re a startup prototyping a microphone/speaker array, a game developer in need of spatial audio, or an artist looking to realize a sonic idea, we’re here to help.

• Early-stage R&D and audio prototyping

• System design reviews and tuning

• Audio UX and interface concepts

• Open-source/community consulting
