What it can do

Read from the source rather than kept as a list: commands from the command line's dispatcher, effects from the effect factory, formats from the code that reads or writes them. The line in each box is its count over the same days as the chart above.

The engine, part by part

The C++ source grouped by what it does, largest first, with each part's growth over the same days.

  1. Effects and instruments

    Built-in effects, the drum machine, FX, sampler, SFZ, SoundFont and DecentSampler players, audio clips, the synth with GarageBand's synths re-created on it, and MIDI effects.

    12,105 27%

  2. Files and formats

    Audio files in and out, MIDI, MusicXML, DAWproject, Bitwig and GarageBand projects, Apple Loops and Logic patches, zip, XML and binary plists, all read with bounds checks.

    8,701 19%

  3. Plugin hosting

    Loads CLAP, VST3 and VST2 plugins and Audio Units, scans and caches them, drives them offline and tests them all (compat); installs free ones (kit).

    4,372 10%

  4. Command line and MCP

    The wavelength command: arguments, every subcommand, help, terminal output and the JSON report; the MCP server, the docs built into the binary and self-upgrade.

    3,959 9%

  5. Render and mix

    The job (with stand-in sounds for missing plugins), tempo and meter maps and automation, then the mix graph: tracks, sends, buses, master; staging faders by role and the track cache.

    3,645 8%

  6. Songs

    The song format: the manifest, revisions with undo and a musical diff, comments pinned to revisions, .wavelength packages and upgrades.

    3,395 7%

  7. Presets and states

    Finds presets by name in 20-odd formats and turns them into the state a plugin loads; audition indexes how they sound.

    3,185 7%

  8. Review server

    The local review page's server (wavelength serve): songs, previews and review comments, the Sounds page with plugins' own windows, and the riff library.

    3,062 7%

  9. Measurement

    Loudness (BS.1770), analysis of pitch, brightness and onsets, the harmony check, and the song picture for agents that can see but not hear.

    2,020 4%

  10. Platform

    What differs on macOS, Linux and Windows: folders, processes, libraries.

    987 2%

Each rectangle is a file (its .cpp and .hpp together), sized by its lines of code and shaded by how many commits changed it: the stronger the blue, the more it has been worked on.
