Includes\nfunctions to visualize notes on a piano using ASCII plots in\nthe console and to plot waveforms using base graphics. It\nallows simple playback of notes and chords using the 'audio'\npackage.", "License": "GPL (>=3)", "URL": "https://github.com/egenn/music", "Encoding": "UTF-8", "Config/roxygen2/version": "8.0.0", "Repository": "https://egenn.r-universe.dev", "Date/Publication": "2026-05-13 16:46:46 UTC", "RemoteUrl": "https://github.com/egenn/music", "RemoteRef": "HEAD", "RemoteSha": "33ed198d5bc786c9e37e41e112eef8060071fe99", "NeedsCompilation": "no", "Packaged": { "Date": "2026-05-13 17:20:53 UTC", "User": "root" }, "Author": "Efstathios D.
