Lineage

This editor descends from prior open-source work in three stages:

WaveEdit

© 2017 Andrew Belt, developed for Synthesis Technology · GPL-3.0

The original C++ / OpenGL wavetable editor, and the source of the DSP engine used here.
OsirisEdit

© 2021 Modbap Modular · portions © 2017 Andrew Belt · GPL-3.0

The C++ desktop editor, a modified version of WaveEdit adapted to the Modbap Osiris hardware spec: Osiris terminology, the Convert / WavPak SD-card workflow, and clipboard additions.
OsirisEdit Web this app

© 2026 Modbap Modular · portions © 2017 Andrew Belt · GPL-3.0

The browser edition. The user interface was rebuilt on HTML, Canvas and Web Audio; the DSP core was ported from the C++ rather than rewritten, and is verified against it.

This is a modified version

OsirisEdit Web is a MODIFIED version of WaveEdit. It is not the original program. Modbap Modular is responsible for these modifications, and for any problems they introduce. Do not report issues with this edition to the upstream authors.

Neither Andrew Belt nor Synthesis Technology endorses, sponsors, or supports this edition. Their names appear here only to give the credit the license requires.

This repository is not a Git fork of WaveEdit: it shares no build system, no language, and no commit history with it. That is a fact about repository mechanics, not about copyright. Because the DSP was ported from the upstream C++ rather than independently reimplemented, this program is a derivative work of WaveEdit and carries the same license. The file-by-file statement of changes is in NOTICE.md.

Your rights

Under the GNU GPL v3 you may:

Run this program for any purpose, commercial or otherwise, with no fee and no permission needed.
Study how it works and change it. The complete source is published, and the pages you are running are the source.
Redistribute copies, modified or not.

The one condition is reciprocity: anything you distribute that is built on this program must itself be released under the GPL v3, with source, and must keep these copyright notices and state what you changed. See the full license text for the exact terms.

Source code

The complete corresponding source for this program is at github.com/modbap/OsirisEditWeb. Upstream source is at github.com/AndrewBelt/WaveEdit and github.com/modbap/OsirisEdit.

Third-party components

This edition bundles no third-party code. The upstream native dependencies were all replaced during the port: pffft by an in-tree real FFT that reproduces its ordered packing, Dear ImGui and SDL2 by browser APIs, libsamplerate and libsndfile by in-tree resampling and WAV code, and ZIP writing by an in-tree CRC-32 + STORE writer. jsdom is a test-only dependency and is never served to the browser.

The typefaces Barlow Condensed, Montserrat and Inter are loaded at runtime from the Google Fonts CDN. No font files are hosted or redistributed here.
