Credits and Third-Party Notices

draw.audio is built on top of several open-source works. The application itself is proprietary, but the components listed below retain their original licenses, reproduced here as required.

Feather Icons

Several inline SVG glyphs throughout the interface are derived from Feather Icons, with the stroke width adjusted from the upstream default.

mitt

A small functional event-emitter library used as draw.audio's runtime event bus.

midi-file

A MIDI file parser/serializer used to power MIDI import and export.

web-vitals

A small library from the Google Chrome team used to record runtime performance metrics.

WaveEdit Factory Wavetables

The wavetables available to the synth's wavetable oscillator are adapted from the WaveEdit Online factory bank that ships with the open-source WaveEdit editor by Andrew Belt. Each single-cycle frame was converted offline into harmonic partials for playback.
