music-practice-bungee-source

This repository is a project-controlled source-availability / durability mirror for third-party software used by Music Practice, a guitar practice app. It is not the Music Practice application source repository — the application source remains separate and proprietary, and is not published here or anywhere else.

What this is

An exact, self-contained snapshot of Bungee Basic v2.4.24 (upstream commit 746833f68a574d997ec50443e7cfd2d37b026302), the MPL-2.0-licensed audio time-stretch/pitch-shift engine that Music Practice compiles, unmodified, into a WebAssembly module. Original upstream project: https://github.com/bungee-audio-stretch/bungee (© Parabola Research Limited).

The snapshot includes the exact pinned contents of Bungee's declared submodules at this commit — Eigen, pffft, and cxxopts — materialized as ordinary directories instead of git submodule references, so the archive is self-contained and does not depend on any third-party git hosting to be usable. See SOURCE-PROVENANCE.md for exact commit pins, upstream URLs, and acquisition details.

Licensing

This mirror does not relicense any upstream software. Every included component remains under whatever licence its own upstream repository states, exactly as reproduced in its original licence files under source/ (Bungee and Eigen: MPL-2.0; pffft: the FFTPACK licence, in pffft.h; cxxopts: MIT). Nothing here is a claim of ownership over, or affiliation with or endorsement by, Parabola Research, the Eigen project, the pffft project, or the cxxopts project.

Why this exists

Bungee Basic's MPL-2.0 licence requires that recipients of the compiled binary be able to obtain the corresponding Source Code Form. Working links to the pinned upstream commits satisfy that today, but upstream repositories can move or disappear. This repository exists to give the project durable, independently-controlled access to the exact source used, for reproducibility and long-term source availability — it is a conservative durability measure, not a claim that MPL-2.0 itself mandates self-hosting.
