Chordmap for Mac 1.0.1

Download Chordmap-for-Mac-1.0.1.dmg (macOS 14 or later, Apple Silicon)

Open the DMG, drag the app to Applications, open it. The first time, macOS says the app is from an unidentified developer: right-click the app, choose Open, then Open again. That is once.

Built and tested on macOS 27. Chordmap for Mac 1.0.1 is built with the macOS 27 SDK and tested on macOS 27: the self-test, the command line against this Mac's own audio devices, and the windows in light and dark.

What changed. On macOS 26 and later the app now draws in the current macOS look, and the sidebar's "Nothing yet" line wraps instead of being cut off. The engine is the same chordmap crate as in 1.0.0, so every chart comes out exactly as it did.

What it asks for. Unchanged: System Audio Recording, once, to hear what the Mac plays; the Microphone, once, only if you pick an input device. Nothing is recorded with either, and nothing leaves the Mac except the optional daily check of this page for a new version.

chordmap 1.0.0

Use it now: https://keithadler.github.io/chordmap/ (nothing to install; or add it to your home screen or dock as an app)

Drop any song you own and get:

• Chart: tempo with tap and half or double, key with its runner-up, chords on every beat (major, minor, sevenths), bars grouped into verse, chorus or hook, 4/4 or 3/4, tuning corrected.
• Capo: the fret that turns the most chords into open shapes, with fingering diagrams for guitar or ukulele.
• Stems: instrumental or vocals in seconds by centre cancel, or vocals, drums, bass and other separated by the MIT KUIELab MDX-Net models running on your own device in the browser, with a stem mixer.
• Play along: loop any section, 50 to 100 percent speed at the same pitch, shift the key six semitones either way, chart again from the stems.
• Keep it: edit chords and section names, recent charts kept in the browser, share a chart by link, export text, ChordPro or MIDI, print.
• See it: waveform map by section, now-playing footer, Stage, Flow and Aurora visualizers, full screen.
• Modes: band, hip hop, dance.

Free, MIT, no account, no analytics. The audio never leaves the device; the only download is the AI model, on request.

Also in this release: the chordmap Rust crate (no I/O, no unsafe), the chordmap CLI (chordmap analyze song.mp3), and the WebAssembly package.

Limits are listed honestly in the README and docs/limitations.md.

Chordmap for Mac 1.0.0

Download Chordmap-for-Mac-1.0.0.dmg (macOS 14 or later, Apple Silicon)

Open the DMG, drag the app to Applications, open it. The first time, macOS says the app is from an unidentified developer: right-click the app, choose Open, then Open again. That is once.

What it does. Play a song in any app on the Mac and see the chords as they go by: the key with its runner-up, the tempo and meter, the bars grouped by section, and where the capo goes so the open shapes play it. Stop, and the whole listen is charted and kept with chordmap's chord sheet to copy. A guitar into an interface works too. It hears; it never records; it does not know the song's name. The engine is the chordmap crate from this repository, linked in as a static library.

What it asks for. System Audio Recording, once, which is how macOS describes hearing what the Mac plays (macOS 14.2 or later); the Microphone, once, only if you pick an input device. Nothing is recorded with either, and nothing leaves the Mac except the optional daily check of this page for a new version.

Honest limits. A clear mix charts well, a wall of distortion less well, and sparse harmony is flagged rather than invented. Major and minor chords and sevenths. Four seconds is the least it will chart; the live view lags by about two seconds. Apple Silicon only in this build; the Intel build follows.
