Audiofile engineering

Hire Audiofile.

Apps, audio engines, firmware, integrations, and end-to-end product development, for music and pro audio brands. Since 2004.

The Audiofile app catalog is built on the same engineering practice — a working portfolio of the work commissioned here. See the apps.

The Craft of Software

Native high-performance apps.

Latest Apple technologies, best-of-breed architecture, novel cross-platform approaches. Carefully designed user experiences for professional audio and music applications.

Building advanced software systems for more than two decades.

DSP & Core Technology

The Audiofile Engine.

A realtime audio core for Apple platforms. Bit-perfect playback, low-latency processing, Audio Unit hosting, and mastering-grade DSP.

The soul of every Audiofile app.

Firmware & Integration

The source behind audio hardware.

Bluetooth, MIDI, USB. Bare-metal signal processing. Real-time constraints, robust I/O, custom protocols. Consumer through pro device categories.

Audiofile firmware powers millions of devices used by creative professionals.

Schematics & Layout

Audio hardware design.

Analog audio circuits, mixed-signal architecture, low-noise PCB layout. Schematic through DFM and factory handoff. From bench prototype to manufacturable unit.

Audio hardware designed alongside the software it runs.

Full Product Development

Sketch to App Store. Sketch to ship-ready unit.

End-to-end audio product engineering with one team. Spec, build, deliver, support: software, firmware, hardware, and the seams between them.
