Peter the musician codes up some audio effects w/ a cool interface to boot!


Audio Experience


How will mobile software expand tonal possibilities for guitarists?

Objective —  Design & code an iOS application to enable greater flexibility for guitarists, encouraging freedom of collaboration.

Design Process

  • Observational Study
  • User Interviews
  • Physical Computing
  • Sound Design
  • Usability Testing
  • Wireframes
  • Information Architecture
  • Task Analysis
  • Visual Identity
  • Interaction Prototyping
  • Interface Design
Old School

Old-School = Bulky + Limited Tonality

Bulky effects pedals limit sonic flexibility for jamming guitarists.


Creative Technology

How do you create digital audio software?

Software Programming  —  Expand coding knowledge & experiment with custom digital effects using freeware IDE Pure Data.



How do you code guitar effects?

Experimentation —  Diving into sound engineering, experiments with audio synthesis & signal editing led to a robust guitar effects software package.


Audio Testing

Can digital out-do analog?

Flexibility —  The expansive possibilities afforded by digital effects enable a greater tonal range compared to analog effects, essentially transforming a guitar into a fully integrated MIDI controller.


By the 6th software iteration, the program could transform a guitar signal into a multitude of instruments, from synths to drums to vocal samples.



What defines minimum viability?

Rapid Testing —  Using a pre-developed GUI shortened development time pre user testing & enabled quicker iteration cycles.



How can the Zephyr experience be tailored to guitarists?

Logo and brand development


Information Architecture



How will an interface represent audio processing?

Visual Design —  Developing a set of icons to represent audio effects allowed Zephyr to communicate using a language already familiar to guitarists.
