Dubnote is an audio note-taking iOS app for musicians, which makes capturing, remembering and using ideas a lot easier. We developed a custom algorithm to separate different parts of an audio recording, and display them as tagged and transcribed clips, revealing at a glance their contents. Designed with a conversational structure, it lets users record directly in notebooks, annotate their clips, and highlight or hide parts of their recordings. I worked on iterative versions of this design, extensively prototyping various interaction concepts, and collaborated with Resonant Design on UI styling.
