This repository is a starter scaffold, not a production DAW. It currently provides:
- a small C library/API;
- a mono graph model with port validation, cycle rejection and topological ordering;
- compiled offline plans with preallocated buffers, sine oscillator, gain, meter and output nodes;
- compiled offline plans with preallocated buffers, sine oscillator, audio source, gain, meter and output nodes;
- C tests for deterministic rendering, routing, validation and lifecycle;
- an optional JACK-compatible mono backend with start/stop, routing and status;
- safe control/audio plan handoff and concurrent replacement tests;
- an optional FLTK shell with engine controls, view switching and backend status;
- a modular graph editor with transactional edits and live plan adoption status;
- versioned project save/load and a timeline for tracks and silent regions;
- versioned project save/load and a timeline for tracks and clips;
- sample-counted transport, selection, move/trim, timeline zoom and scrolling;
- WAV import/graph playback, bounded recording and missing-asset relinking;
- architecture, format, GUI, roadmap, and decision documents.
The JACK backend has passed software-loopback testing; physical-device playback
is unverified. Recording, audio-region playback, MIDI and plugin hosting are not implemented yet.

With JACK development files and an existing JACK-compatible server, run the
isolated software-loopback test with `make test-jack`. It connects only test
isolated software-loopback test with `make test-jack` and the record/reopen/play
acceptance test with `make test-jack-audio`. It connects only test
clients. See [engine documentation](docs/AUDIO_ENGINE.md) for configuration,
routing, ownership and recovery.
